Del-Val 101 Single-Prime


Del-Val 101 Single-Prime Etching Primer is a solvent-based primer designed to maximize adhesion to surfaces that can be difficult to adhere to, such as TPO, PVC, Hypalon, Metal and a variety of other substrates. It is a fast-drying primer that provides strong adhesion on weathered and un-weathered surfaces. Del-Val 101 is intended for use over a cleaned roof surface; contaminants such as dirt and debris prevent proper adhesion.


Del-Val 101 Single-Prime Etching Primer lays an excellent foundation surface for coating a roof with our Del-Val 320 Silicone Roof Coating for example.


All surfaces must be clean and dry and free of any oil, grease, dirt and all other foreign matter.


Apply Del-Val 101 until roof appears to be a consistent charcoal color. Apply primer with small airless sprayer or a medium nap roller. Over-application or use of multiple coats can reduce adhesion performance. Del-Val 101 should be top coated within 7 days.


Apply at a rate of 330 square feet per gallon (0.33 gallons per square). Additional material may be required for porous substrates. Must stir before using.
