## Description

Liquid Rubber Multi-Purpose Primer is a high-performance engineered bonding aid formulated to improve the adhesion of Liquid Rubber membranes to a variety of substrates. Our Multi-Purpose Primer is a single component composition suitable for easy and safe application to numerous surfaces including concrete, wood and high-density polyethylene by means of brush, rollers or spray equipment. Our Mulit-Purpose Primer reduces peeling, flaking and vapor drive from substrates. Application: Liquid Rubber Multi-Purpose Primer may be applied as a single component system using either manual or spray application methods. Manual application can be carried out using a conventional brush or roller equipment or alternatively, the product may be sprayed using a delivery system and nozzle appropriate for the viscosity of the material. Apply 1-2 coats depending on surface. The recommended coating thickness is between 4-5 mils DFT (.01 mm). For best results, the Multi-Purpose Primer should be applied to a dry surface that is free of dirt, debris, oil, silicone, laitance and efflorescence. Do not apply if rain is forecast within 24-hours. Drying Time Curing time will vary depending on the temperature and relative humidity. Typically, Multi Purpose Primer will be dry to the touch and ready for top coating within 1-hours to 2-hours at 20°C (68°F).

• Improves adhesion and prevents blistering on surfaces
• Fast-drying formula ideal for wood, concrete, and HDPE
• Water-based, non-toxic, and low VOC for safe use
