In the wood finishing area , we have the ability to use wood varnish that is from natural elements , as the pure double boiled( that we boil ourselves ) linseed oil and chemical based varnish .

No matter what type you choose , the wood varnish is a super efficient and a super basic wood finishing ingredient and can be used to any woodworking plan and type of wood you have .

What is exactly , the wood varnish ?

The wood varnish is a natural – chemical or a mixture of these liquid , transparent or not ( we have widenly colored varnishes ) , durable but also flexible layer and protecting film that consist of : several types of oils , several types of resins , acrylics , epoxy and water or chemicals , as solvents .

The below is a color varnish job to a quitar .

What does Varnish do ?

The varnish does several jobs to a wood piece , such as the protection from external factors , the final strong but flexible finishing , the scratch prevention , the total sealing of wood(polyurethanes) , undercoat jobs if you use an impregnated varnish and primer jobs , are some of the varnish’s jobs to wood .

The wood varnish gives durability and strength to a wooden surface , but with flexibility and not stiffness . ath the same time , especially the non crust film , varnishes .

Does varnish make wood , Look better ?

Yes , one of the varnish “missions” , is to upgrade the external looks to a wood piece , in amazing heights , of beautiness , no matter what kind of varnish , you choose .

Do you Stir varnish , Before using ?

Yes , you try to give your varnish a uniform mass , before you apply it to your wood , in order to apply it easier and in the same dosages to the surface .

Is varnish good , for Plywood ?

Yes , you can use any type of varnish you like to a plywood piece and for sure it’ll upgrade its external looks very high .

Many times the resins a varnish has , are bonding very nice and strong with the plywood’s resins , the manufaturers use to make them .

Remember the plywood is many veneer( from several wood types ) glued and pressured together with several resins – glues .

What is the most Common , wood varnish ?

The most common varnishes are the oil based ones , before the modern times evolution and of course one of the best natural varnish , is the boiled linseed oil .

The one you boil yourself , not the boiled one you fing in the stores and has solvents inside .

See the my favorite linseed oil products to get from the stores in HERE .

Is it oK , Not to varnish wood ?

Yes , if you like you cannot varnish your wood and you can choose another type of wood finishing .

See some of the best totally natural wood finishing combinations , in HERE .

Does varnish Waterproof wood ?

Yes , it can make the wood waterproof in a high level and if you choose a polyurethane varnish with much polyurethane perventage inside , you can seal totally the wooden surface .

Remember the polyurethane is basically a plastic and from a plastic film , nothing can penetrate . Of course this plastic types of finishes aren’t perfect and they have their disadvantages .

The natural oils and their mixtures can waterproof also the wood , but not totally .

Why does varnish , turn wood White when Wet ?

This will happen to your wood from the high moisture that is inside the wood and mixed with the oil based varnishes mostly .

How long does varnish need to dry , before Rain on wood ?

This depends from the type of wood you have , the type of varnish and the place you’re acting woodworking .

The oil varnishes , need many days especially when there’re totally natural . The chemical based varnishes , may need from a couple of hours(12) , to a couple of days for fully drying .

You may find a polyurethane varnish , that can be ready in 8 – 12 hours .

What happens , if it rains on Fresh varnish ?

No mater what type of varnish you have , if it’s not totally dried , the water molecules will penetrate the wood’s mass , creating problems from discoloring – dissolving , to the total finishing destruction .

Does varnish , Stop wood from Rotting ?

When a varnish molecule( any type ) “catches” its place inside the wood’s mass , no other molecule can come closer . There is no room !!!

So in this way , the varnishes are preventing the rot and in many cases( polyurethane ) , in a very high level .

Does varnish , stop wood Splitting ?

Yes , certainly they do make wood more strong , because they penetrate inside and when they dry , they solidize the wood’s mass , generally .

You can make varnish combinations and maximize this feature , very easy .

See some of the best natural & chemical finishing combinations , in HERE .

Does varnish , Stops Mold ?

Yes they stop mold , because the varnishes in general they create a protecting strong , but flexible film in a wooden surface or in its inside mass( impegnated ones ) and this film is a stop barrier to mold and not only .

Of course they don’t cure mold or other wood illnesses . If you have serious mold and other wood illnesses , you need wood medicines and then varnishes and all the others .

What varnish is Best for wood ?

The best wood varnish is the exact one , which will accomplish perfectly the exact “mission” and final result you want from it and for the longest time period .

If you don’t want a crust film making varnish , you won’t get a lacquer one or a crust polyurethane one or a synthetic shellac , et.c . You’ll get one which allows wood to “breathe” .

If you want a crust film making varnish , you won’t get a linseed oil or a decking oil varnish , but you’ll focus in the polyurethane area ones , or a shellac one , or a lacquer , et.c .

The wood job you have , will “deside” what type of varnish is the best for the job .

Is varnish , Better than stain ?

There are different materials , even if stain penetrates inside the wood mass , as the varnishes do . The varnish is focused on protecting the wood in many different ways , while the stain is focused to change its color .

The stain gets inside , while most of the varnishes are creating an outside protecting film . The varnishes protects more than a stain for sure and in most cased , way more a stain .

See in HERE some of the most classical stains to coloring your wood .

Is it Better to Oil or Varnish wood ?

The varnish may contain oil or several types of oils . Generally the varnishes are better protectors than a single – alone oil , especially for the outdoor – sea tough conditions .

Should i Oil wood , Before varnishing ?

It’s not necessary to use an oil as an undercoat before your varnishing , but you can do it if you want a specific result , or to solidize the inner fibers to the maximum, before you apply your varnish film .

You may want to hydrate more your inside wood maybe , or to fill some minor cracks it may have , or whatever else for the external looks of it .

I suggest you to try to combine the undercoat oil you’ll use , with the upper varnish you’ll use after the drying , because you’ll have better bonding .

Is wood Oil , the Same as varnish ?

No , it’s not even if many varnishes are made only from oils or they have oils as their ingredients .

The varnishes are made from several oils , resin , polyurethane , acrulic , epoxy and water or solvents , while the oil is made only from oil .

The only oil varnish which comes from only one oil , is the boiled linseed oil you boil yourself and polymerize the oil , making it a varnish .

Is Linseed oil a varnish ?

No , in its pure natural form it’s not it’s just an amazing oil , but if you boil yourself the linseed oil , the heat polymerize big the linseed acids , tranforming it into a first class natural varnish .

Why linseed oil , is Used in varnishing ?

The linseed oil is an amazing oil and it’s a first class element to use for varnish mixture , because of its unique features and beautiness it provides to any type of wood .

The linseed oil while it’s drying , it make the wood’s mass more solid but not stiff , giving to the fibers amazing features .

Except all its benefits , there is no other oil that can reach the beautiness and shades to wood , the linseed oil gives .

If you want the complete post for the linseed oil , go HERE .

Is varnish , better than Paint ?

There are different materials for the wood finishing and the paint is more strong than a varnish for the outdoor conditions , except only from the most durable polyurethane varnish ones .

The paint can last more than a varnish outdoors and has a better UV protection , but most of the times you need to use an undercoat before you paint your wood .

A nice primer goes usually with a good paint .

Does varnish , Ruin Paint ?

No it doesn’t , on the contrary , it generally protects the wood surface and provides durability , strength , flexibility and a very nice looks to any type of wood , to any type of paint , when you use it as a top coat .

If you can have your paint and varnish , having the same or close chemical formula , even better , concerning the bonding between the varnish and the paint .

What is Better , varnish or Polyurethane ?

The polyurethane is literally liquid plastic and of course , nothing can win plastic , concerning the strength and the power of the film , it provides to a wood piece .

The polyurethane , makes a strong barrier – film to wood and it it doesn’t let anything to pass this film , but of course this has disadvantages .

The varnish is less powerful concerning the protecting film , but it’s more flexible and adapt to the wood’s moves .

A crust polyurethane film( if you have this one ) is a top sealer to a wooden surface , but this crust isn’t “immortal” to time . Sooner or later , it’ll brake letting moisture penetrates the wood and after a long time it’ll leave the wood unprotected generally .

This applies for all the crust types of wood finishing elements .

If you check your house’s floor or something that has a crust film on it , you’ll see black lines between the connections of the wood parts .

This is the moisture , that has “seen” these crust weak spots and went inside the wood .

So every element has it’s pros and its cons .

What is better , Laquer or varnish ?

Generally the laquer dries faster than a varnish , but it’s a thinner wood finishing . The protecting film of the laquer is stronger than most of the varnishes , except the very strong polyurethane ones .

The varnish is more flexible than a laquer finish , but the laquer gives more uniform and glossy results . The musical instrument creators , appreciate this feature of laquer .

Can you paint , Over varnish ?

Yes surely you can , even if the varnish is used as a final coat most of the times but try to have the same chemical formula for these two materials . You’ll have nice compability and better bonding , thing that will provide a very nice final results .

If you use an oil paint , use and oil based varnish , or a water based for both , et.c .

Can you Paint wood , Then varnish ?

Yes , surely you can and this is the most classical way to use and combine paint and varnish , because the varnish comes as a final coat , sealing your previous steps .

What happens if you varnish , Over varnish ?

This is a very nice solution and combination for any type of wood , especially if you use a natural oil varnish as a precoat and then maybe a very strong polyurethane , to seal all this very strong .

You can use two oil based varnishes if you like , or two water based varnishes . Try to use the same chemical formula varnishes , for better bonding of these elements .

Surely , your final result will be , a very strong result and if you sand a little between the coating layers , even better .

Can you varnish , Over Old varnish ?

Yes , you can do it , but you’ll have surely uniformity and appearence themes , even if you sand the surface and you’ll use the same formula varnishes .

The old varnish has “matured” over time taking a unique color and shade , thing that it’s not possible the fresh varnish to get close to .

The correct way is to remove totally the old varnish and then use your new one and do the process you want with your undercoats and final finishing .

How many coats of varnish , should you put on wood ?

This depends from the type of wood you have and how it absorbs the varnish , the type of varnish you’ll use , the level of protection you want to provide and of course the final appearence result , you want .

Usually a couple of coats ( 2 – 3 ) are enough to make a nice final result .

You should always have in mind that the varnishes in general are thick finishings and you should be aware of the dimensions of the place you’ll put your wood project .

If you have very strict area ( as a kitchen cabinets ) , you should count this thickness to your design measures .

What are the Pros and Cons of the varnish ?

All varnishes ( natural or chemical ) give unique beautiness to a wooden surface . The natural ones give also great flexibility to wood , along with the strength they provide .

The varnishes are also not expensive materials for finishing .

They need and require the safety measures ( face mask – gloves , et.c ) and there aren’t very resistant to abrasion and the scratches , especially the non polyurethane ones .

The chemical varnishes aren’t eco friendly and they harm the health , if you don’t take your safety measures .

How many Years , does varnish last ?

This depends for the type of your wood , the type of the varnish( crust or not ) , the generic weather conditions and the treatment you’ll give to your varnish and of course the how many recoats , you’ll make and maintain your wood plan .

Under “normal” cirmumstances a good varnish can last more than 8 to 10 years and in some cases , way more .

If you recoat , you can have effective protecting results up to 15 – 20 years .

Does varnish , makes wood last Forever ?

No it cannot make wood last for ever and nothing on this Earth can last forever , but you can make wood last for many decades , using a very good varnish , oil or chemical one .

Maybe from this fact , i have this love for linseed oil , but i remember that he lightly sand the windows and he applied a couple of layers of linseed oil and that’s it . Nothing else !!!!!

This depends from the final result and texture you want your wood to have , after your varnish treatment and if your surface has big cracks , damages and discontinuities , you need to fix with a good sanding .

It’s not necessary if you don’t want to .

Do you need to Sand , Between every coat of varnish ?

Yes , if you like to smoothen the surface and keep it smooth , while you apply varnish and you want good uniformity , while the drying process .

The constantly varnish “building” need attention , concerning the general uniformity of the finishing .

Should you Lightly sand , between coats of varnish ?

This will help for sure the next varnish coating layers , the easiness of your next applying and of course the general smoothness of your wooden surface .

Of course a smooth surface , needs less varnish and the coverage is better .

What Sandaper , to use Between varnish coats ?

You need a light sand paper to use for your sanding between the coats of varnish . You don’t shape wood between coating , you adjust – slightly correct the surface .

Check in HERE , some of he most basic sandpapers and abrasives .

Is it Better to varnish with a Roller or a Brush ?

The roller gives a more uniform result to a smooth wooden surface than the brush and the applying is more easy , especially to bigger surfaces .

In a not smooth surface , the roller isn’t so good and it cannot cover the whole surface at once , without extra comeback coverage . The brush in here is better .

You should use a natural hair brush for oil based varnishes and a synthetic brush for water based and acrylic based varnishes .

What is the Best way to Apply varnish ?

The best way is to have a very nice smooth surface , without discontinuities and use a nice brush in order to make the varnish penetrate more inside the wood’s fibers , using along the grain moves or circular ones .

Here are the best brush suggestions to get from the markets .

Can i use Cloth , to apply varnish ?

Yes , you can use a cloth to apply varnish but it’s not recommend it , because you need the penetrating moves of a nice brush , to push the varnish inside the wood’s mass and make a total coverage , even in the smallest gaps .

Can you Apply varnish , with a Sponge ?

Yes , you can apply using a sponge , which is better than a cloth , but it cannot reach the ability of a nice hair brush , to penetrate to the smallest spots of wood .

How do you Apply varnish , Without a Brush ?

How do you Apply varnish , without brush Marks ?

You need to have the appropriate brush for the type of varnish you use and the area you’re about to varnish , concerning the brush’s width and of course the wooden surface should be the smoothest , possible .

The varnish applying with a brush is tougher than a roller . You should apply varnish along with the grain and have the ability to “read” the surface’s “thirst” , in order to grab only the appropriate varnish amount , neither more or less .

This ability is super useful . You grab with your brush only the correct varnish amount to cover the spot and have smoothness , the same time .

After the first coats , the applying will be easier and the “danger” to leave brush marks , smaller .

How do you Apply varnish Successfully ?

1) You should prepare your wooden surface perfectly and make it clear from previous coats and the smoothest( if you want smoothness ) , you can .

2) You should have the appropriate brush ( size , material ) , or roller ,or whatever you want to apply your varnish , for the type of varnish you’ll use .

I suggest you a nice brush or a roller .

3) Try to have correct environment circumstances . Low air , low dust , zero sun , not extreme temperatures .

4) Put your woodworking project – surface , in a place totally stable and comfortable for your moves .

5) Have your varnish , well mixed , before you grab your varnish with your brush – roller .

6) Grab with your brush – roller only the appropriate amount of material , to cover the spot you want .

7) Apply varnish , along with the grain .

8) Use the “built” method to cover the area to the level you want . Make light and many layers of varnish coats , than use less layers and big amount of material .

9) If you want smoothness , you should sand before the varnishing and between the coats . Use medium and light sandpapers .

10) Let it dry , normally and naturally , before you use your surface .

How do you get a Smooth finish , After varnish ?

After the varnish applying , smoothness gives the correct and light sanding with a good quality sandpaper( very light coarse ) , or a steel wool if you want minor details fixing .

You may use even the well known Scotch Brite sponges and if you want you can make a final coating and seal more your varnish , making it extremely smooth , also .

The laquers and the shellac , are providing extra smooth and uniform results . The expensive pianos , musical instruments , et.c , use these two .

Is One layer of varnish , Enough ?

No , usually you need more layers of varnish to fully cover and seal a wooden surface , but if your surface is super smooth , the wood’s density is big( low soak ) and your varnish is a thick one , you may do your job ,with one layer .

Rare , but it can be done .
