I was planning on using Mesmers to seal both the ends and tops of my IPE deck boards. Just heard from someone who has done alot of installations and says I should only seal the cut ends and the sealing the tops is a bad idea because the seal won't absorb and you''ll get weird staining patters that will require sanding the whole deck down. I heard of this from others as well. anyone have experience with this.
Cut ends of ipe MUST be sealed with anchorseal. Otherwise they'll end up checking at the ends (cracking) due to moisture loss. Anchorseal is available from most deck suppliers. Stain/sealer is not an appropriate product for end grain sealing.'
I've had great luck with Penofin on ipe. Works great. Fact is you can seal the ends and not do anything to the rest of the boards and they'll last decades. They'll just weather down to a silver-gray color.
