NS97 Exterior Primer, 1 Gallon

NS97 exterior primer preps exterior substrates so waterproofing and crack-isolation membranes bond where they'll see weather. Roll or brush it on before you apply membrane, and it seals the surface and gives the coating a solid grip.

This one-gallon jug handles the priming step on exterior decks, balconies, and walls headed for a membrane system. Prime first so the membrane bonds instead of blistering or peeling once it's exposed to sun and moisture.

A membrane is only as good as its bond to the substrate, and that bond starts with primer. Pros never skip it. Tile Outlets stocks NS97 exterior primer to start your exterior waterproofing on the right footing.
