Application Equipment & Coverage:


Liquid Rubber Multi-Purpose Primer is applied using a single component system using either by brush, roller or spray application. This primer will require one to two coats depending on the absorbent nature of the substrate, with the goal of minimizing vapor drive and maximizing adhesion of the waterproof membrane.


The recommended coating thickness of the Multi-Purpose Primer is between 4-5 mils DFT (.01 mm) (200-250 ft2/gal). For best results, the Multi-Purpose Primer should be applied to a dry surface that is free of dirt, debris, oil and grease. Application immediately before the onset of rain is not recommended. Apply a minimum final thickness of 1 gallon per 175 - 200 sq ft (18.58 sq/m).
