The pure acrylic coating was included as a reference, as well as the oil-based penetrating finish Organiclear.
The performance of the penetrating finish Organiclear remained rather steady during the cycling.
After the wood dries, restain or apply a clear penetrating finish. Clear finishes show more of the wood's original color but must be reapplied every year.
"For the table, a penetrating finish like Watco is great.
The oil-based semitransparent stain (FPL-046) was not evaluated for finish cracking because it is a penetrating finish with no film buildup and therefore not susceptible to cracking.
The service life of this type of penetrating finish is determined by its erosion rate.
If you aren't, you won't need to raise grain unless the piece has a penetrating finish and will be placed in a moist environment.
Clear penetrating finishes lasted only 1 to 2 years, and semitransparent finishes performed well only on saw-textured lumber.
For the vertical exposure (siding application), all six methods (five finishes and the control) were used; for the horizontal exposure (decking application), only the penetrating finishes were used (finishes 2; 3, and 4, plus the control).
For wood finished with clear penetrating finishes, dimensional changes caused by wetting-drying cycles may lead to raised grain, checking, and cracking of the wood.
For penetrating finishes, this degradation is not serious because the wood can be refinished without extensive surface preparation; film-forming finishes often require extensive surface preparation, even to the extent of complete removal of the old finish, prior to refinishing.
Clear penetrating finishes allow the grain and color to shine through, but offer less protection against ultraviolet light, water and other elements; the wood is more likely to fade.
