## Overview

The ALCM Low VOC Asphalt Primer is a high-performance, eco-friendly primer designed for weathered roofing surfaces. With a maximum VOC of 350 g/l and 63% solids by weight, it ensures strong adhesion and weatherproofing while complying with stringent environmental standards. Ideal for metal and concrete roofs, it covers 100 square feet per gallon and offers a durable, matte black finish that prepares surfaces for premium asphalt coatings.

## Description

The ALCM Asphalt Primer is a premium blend of asphalts and solvents formulated to penetrate and restore lost oils of old, dry roofing felts. This low VOC primer provides a sound base for the application of asphalt coatings, adhesives, emulsions, and cements. The recommended application rate for this primer is 8 to 16 mils of wet film thickness. ALCM manufactures this Asphalt Primer for use on weathered metal and previously uncoated concrete roofs.

Review: Easy to apply. Chat GPT approved - Arrived on due date. Very competitively priced. Easy to apply. Too early to tell about the quality and lifetime. I have never used an asphalt primer before but AI recommends it. Checked the specs with Chat GPT for guidance.
Review: It works, but slow cure time. - This primer worked for the GAF rolled roofing I installed. Their premium rolled roofing. This however is the slow drying primer. So instead of just an hour cure time it has a 24 hour cure time. Luckily it worked out for me. Good weather and this being the final step to finish the day really helped. And since this is almost impossible to find anywhere, I didn't have much choice.

### ⭐⭐⭐⭐⭐ Very easy to apply. Works just fine on raw plywood.
*by R***T on September 5, 2024*

The instructions say not for use on wood, but I don't see why they would say that. It worked perfectly for me on my raw plywood. Application using a paint roller was fast and easy. I then laid my roofing material on, starting with the lowest row and then proceeding up the roof with each row overlapping 4".
