Oil and oil polished should not be built up on the surface of the wood because the cure too soft. Therefore, they can’t safeguard by forming a thick film, as further finishes do among the wood and the surrounding environment. Any shield oil and oil finishes present has to be also in the wood or very thin on the surface of the wood. In fact, it is a little of each, and both are necessary to complete maximum defense.
Oil and oil finishes don’t provide much shield against water vapor exchange. But what little protection they give comes from the polish that penetrates the wood. A barrier forms just below the surface, which slows the switch of water vapor and thus reduce swelling and shrinking. The varnish that remains on the surface of the wood offer limited defense opposed to stains, water damage (smudges), and abrasion.
Straight oil soaks into the wood much more deeply than oil blends because straight oil takes much longer to cure. But oil blends usually form a better surface barrier because of the added oil. Neither polish provides reasonably much defense opposed to abrasion or water damage, because they are so soft and thin. It is therefore important that you care for the integrity of the surface film by recoating it anytime it becomes scratched, worn, or dull.
To complete the best shield your garden furniture with an oil blend, you have to create continuous film, one with no voids. The best way to do this is to apply the first couple of coats pretty wet and let the saturate in for at least five minutes before wiping them off. The heavy, wet cat will allow the varnish time to penetrate and form an internal barrier against water steam exchange. It will also stop up the larger pores so a unremitting film can form over them.
