Kst Coating KS0063300-20 Elastomeric Roof Coating 4.75 Gal

Product Description

The KST COATING KS0063300-20 is a white elastomeric roof coating formulated with a durable acrylic elastomeric resin designed to protect low-slope and flat roofing systems from moisture infiltration and weather-related wear. This 4.75-gallon pail covers residential and light commercial applications where a flexible, long-lasting barrier is needed. The coating forms a rubber-like membrane that expands and contracts with the roof deck through thermal cycling, maintaining adhesion and sealing integrity across a wide service temperature range of -10 to 160 degrees F. Licensed roofing contractors and general contractors install this product during re-coat and restoration projects.

This coating is suited for residential rooftops, mobile home roofs, and light commercial low-slope roof surfaces where reflectivity and waterproofing are primary concerns. The white finish reflects solar energy, contributing to reported energy savings of up to 35 percent compared to uncoated dark roof surfaces. It is applied over existing roofing substrates in need of sealing or restoration, helping extend service life without full replacement. The formulation is mildew and algae resistant, making it appropriate for humid or coastal climates where biological growth is a recurring maintenance issue.

Key Features

Compatibility

Designed as an elastomeric roof coating for residential and light commercial low-slope roofing applications requiring a flexible, waterproofing membrane layer.

Installation Notes

Application is typically performed by licensed roofing contractors or qualified general contractors. The roof surface must be clean, dry, and free of loose debris, oils, and standing water before application. Apply at recommended spread rates using a brush, roller, or airless sprayer rated for latex coatings. Do not apply if rain is forecast within 24 hours or if surface or ambient temperatures fall below manufacturer guidelines.
