Acrylic Roof Coatings

Acrylic Roof Coatings are environmentally friendly roofing products designed to permanently repair persistent roof problems such as roof leaks.

Acrylic Roof Coatings have little odor and can be applied without disrupting the occupants in the building. This makes acrylic coatings ideal for buildings that function as schools, residences, food preparation areas, hospitals and offices.

Lexis Acrylic Elastomeric Roof Coatings

Lexis Coatings offers various types of acrylic roof coatings for almost any roof type:

1. EnergyGuard® Acrylic Elastomeric Coating
2. EnergyGuard® Acrylic Clear Coat
3. SeamStitch® Acrylic Elastomeric Caulk
4. PrimeLock® Acrylic Primer
5. PrimeLock® Bonding Primer

Roof Coating Application & Specifications

Application of water-based acrylic coatings do not require extraordinary personal protective equipment. The equipment usually required is no more than a pressure washer, paddle mixer and airless sprayer. This makes it easy for roofing contractors to enter into the coatings application market.

Facilities with in-house maintenance personnel can also install roof coatings themselves provided they take necessary safety precautions and follow the application specifications.

1. Built Up Roof Repair
2. Concrete Roof Repair
3. Metal Roof Repair
4. Modified Bitumen Roof Coating
5. Polyurethane Foam Roof Coating
6. Single Ply Roof Coating

Acrylic Roof Coatings are Energy Efficient

Energy-efficient roof systems are in demand. Rising energy costs and the effects of urban heat islands have made white, reflective roof systems the product of choice for most roof maintenance applications. Using energy-efficient roofing materials results in cooler roof surfaces and less energy spent for air conditioning.

White, water based acrylic roof coatings provide the highest reflectivity and the best longevity at the most economical price.

Because of media attention about ENERGY STAR ratings and reflectivity, roof coatings frequently are specified as finish coats for built-up and modified bitumen roof systems and maintenance coatings for existing roof systems, including built-up, modified bitumen, metal roofing, spray polyurethane foam, concrete and single ply.

What are Acrylic Coatings?

Acrylic coatings are liquid coating systems based on acrylic resins. Generally, a latex-based coating system that cures by air drying. Acrylic coatings are formulated with pigments, acrylic polymers and water. Pigments, such as titanium dioxide, produce the white color, which provides the desired ENERGY STAR-compliant reflectivity.

Various Options for Acrylic Roof Coatings

• Acrylic Coating over Smooth Built Up Roofing
  • An asphalt emulsion must be applied to stabilize the surface. Asphalt emulsions add additional surface waterproofing capabilities.
• Acrylic Coating over Granulated Modified Bitumen
  • A bonding primer can minimize blisters and pinholes in the topcoat.
• Acrylic Coating over Metal Roofing
  • Galvanized metal is an excellent substrate for acrylic coatings. Solvent based alkyd coatings can adversely react with zinc and lead to flaking of the alkyd paint from the roof. Do not use acrylic coatings over a Kynar® coated sheet. Rust primers are available that seal rusted metal surfaces to ensure moisture and oxygen cannot penetrate and cause the metal to continue to rust.
