WHAT IS THE PURPOSE OF A LIQUID/FLUID APPLIED ROOFING PRIMER?

A liquid/fluid applied roofing primer is used after the roof is properly cleared of any other debris and prepped for the work to begin. Once this is completed, the project must be evaluated to see what kind of primer must be used depending on the substrate that the work is being done to. Sika’s wide selection of liquid/fluid applied roofing primers are ideal for any project, browse our products below to see which best suits your next job!
