5 years ago we applied weatherall 2 coats of stain and 1 coat of gloss. It is peeling we plan to corn cob blast or glass blast which do you prefer. We live in western Nebraska, lots of wind. We erected a new garage and tried permachink ultra 2 sequoia brown stain with 1 advance gloss top coat. wanted to do this to compare products. 8 months later already peeling. What do we do before we tackle our house which is 4800 sq ft. Do we have to wash it after we blast it, or stain it after blsting it?
Did you sand the garage before you stained it? The mill glaze must be removed on new construction before applying any stain, else it will peel.
As long as you blow and brush all of the corn of before staining you should not have to wash it before staining (Perma Chink disagrees) IF you apply a borate to dampen the wood before staining.
