Complete Waterproofing Solution

Rubber Coat

Rubber Coat® is a modified elastomeric asphalt emulsion specifically formulated for application by brush, squeegee or roller. Rubber Coat® is a cold applied, single component product that yields a membrane with excellent strength, elasticity and adhesion. Rubber Coat® is an environmentally friendly waterproofing product that can be applied indoors and outdoors with conventional protective equipment.*

Rubber Coat® is a water-based, environmentally safe alternative to conventional hot-applied, solvent based and sheet membrane waterproofing systems. Since Rubber Coat® cures by evaporation, a minimum application temperature of min. 40oF (4.5oC) is required. Apply in thin coats. The product cures within 24-48 hours at 70oF (21oC) and 50% relative humidity, at a thickness of 40 mils (1mm).

For best results, surfaces must be dry and free of dirt, debris, oil or grease. Application is not recommended if rain is imminent, or in high humidity environments.

Rubber Coat® is applied between 20-30 ft2/gal (0.3-0.7 m2/litre) to produce a 40-60 mil (1-3 mm) protective membrane. Rubber Coat® dries to the touch within minutes at 70oF (21oC). Curing time will vary depending on temperature and relative humidity.


*Rubber Coat® is mildly alkaline. When applying this product observe appropriate safety precautions, wear gloves, eye protection and other suitable protective equipment. For further information please consult the product MSDS.

Rubber Coat® should not be applied when the ambient temperature is below 40oF (4.5oC). The uncured membrane may be damaged if frozen. Some surface base coats, such as coal tar are unsuitable for use with Rubber Coat®.


For industrial use only. Keep out of reach of children. Avoid storage below 40oF (4.5oC). Please consult the MSDS before using Rubber Coat®.
