1 gallon of AQUAMIX SEALER on Sale
RenoDepot has AQUAMIX SEALER has it on sale for $109.20, with $10 coupon is be $99 for 1 gallon of sealer. I have a whole new build home to seal, 3 x washrooms, foyer, laundry room, and foyer. Don't think I'll need a whole gallon, but does this stuff expire? If I only use 1 litre for what I need to I just seal the cap and it be good in 3 years time for reuse? Or is there some special way of storing it?
