Have a deck that is made (thank goodness) from pressure treated wood. Deck is about 20 years old.
Will be wanting to apply some product like Thompsons Water Seal to it.
a. Is Thompson's the brand to use, or are there "better" products available ?
b. How is this stuff applied ? Just swabbed on with a big, cheap, paintbrush, or... ?
How about spraying it on ? If so, would you still need to smooth the liquid with a brush ?
c. The underside of the Deck is high enough to walk under.
Should I also apply this stuff to the underside ? Brush or spray ?
d. How does one get the sides of the planks, seeing that there is about an 1/8 inch gap, only ?
Important to do the sides too ?
e. Does pressure treasted wood absorb any of this product, or is it pretty much of a surface treatment ?
Just out of curiosity, how about regular wood: surface only ?
