Another serious product – helper for the pre- finishing treatment of a woodworking project is the wood sealer and its importance is undeniable for all kinds of projects , for all kinds of wood .
The wood sealer is a serious helper for the general condition of the wood and it isn’t “another filler the markets have” .
I know that the big number of the wood treatment products , may be confused and many may think that all are the same , but this isn’t the case .
I say this to all of this series of articles , concerning the pre-finishing and finishing products for woodworking .
“Every product the manufacturers create are mainly focused to do only one job 100% good and the best they can . If parallel they can accomplish something extra , it’s ok .”
But their main job is one and their chemical formula is targeted to do this main job , the best it possible can do .
The wood sealer is firstly a top product to seal wood and then maybe something else extra .
A great wood sealer is the wax , even if it’s not as the sealers you find in the stores . Nothing gets inside the wood’s mass if you wax it as a last finishing layer .
See in HERE , my top product sealer suggestions to get from the markets .
What does a sealer do to wood ?
The primary job of a sealer , is to seal the wood and don’t let anything to pass from one side of it , to the other side , preventing in this way the wear , the water – moisture which wants to penetrate wood , the discoloring the high UV’s and whatever else wants to go inside the wood’s mass .
The wood sealer has a chemical formula focused to seal wood and don’t let anything penetrate inside , as a well armored door does to a safe deposit .

The sealant is to fill bigger holes and discontinuities to wood and it’s like the wood putty , while the sealer goes deep inside the wood , make it impenetrable to any factor which wants to enter its mass .
Does Varnish , seal wood ?
There are different products , with different chemical formulas , as the wood sealer , seals wood in every place and every condition as a pre – finishing treatment , while the varnish is last finishing layer of a wooden project , mostly for indoors circumstances .

Does wood sealer make wood Waterproof ?
Yes , in a very high level , but not totally waterproof and not for ever . To make the wood totally waterproof and for ever is a very difficult “puzzle” – situation and maybe it’s not possible with 100% efficiency .

This depends from the type of sealer you use , the type of wood you have , the general weather conditions , the last finishing product you’ll use and the generic treatment you’ll give to your wooden surface .

When you want for any reason to seal a wooden piece – project , from any external unwanted situation , you may use a sealer and i suggest you when you do that , try to have the wood pores as open as you can , let ir dry , then sand a little and proceed to your last top coating .
The aggresive sanding makes the pores wide open and after the sealer’s dryuing you may use a light sandpaper to smoothen the whole thing and make it uniform .
