Primer Sand


Priming of most surfaces (new wallboard/drywall or old painted walls) is crucial to properly applying American Clay plasters. Primer Sand is meant to be mixed with an approved paint primer and then rolled onto your wall. This creates tooth that aids American Clay plasters in properly adhering to the surface. The mixture of Primer Sand (a unique blend of light weight sand aggregates) and an isolating paint primer will produce a textured sand primer which will prepare your wall for plaster application.
Primer Sand can be used with both conventional and zero- or low-VOC primers. Below is a list of approved brands of primers:
