I just recently had an ipe deck installed. The contractor doing it did not use end grain sealer. Now I'm worried. Question is, is it too late to apply it? He has to come back to finish some other stuff. Should I have him apply anchorseal now? We could get to most ends by removing a couple of the outside boards that line it. It's been about a month or so since most of the wood was cut. I live in NE and it is getting colder and drier quickly here. Some boards have some checking already but most do not yet. A couple of the 4x4 posts have very bad face checking already. Is it a bad idea to seal the ends now after the wood has dried out quite a bit already?
