Roof coatings have an elastic property that allows for expansion without damage. The thickness varies from product to product, but, in general, run up from a paint type thickness up to 40 dry mills. A roof coating is a protective membrane and the top layer of a roof, and it offers protection from climatic conditions and impact. elastomeric roof coatings are premium coatings with extra protective properties promoting long life and high performance.
Properties
Elastomeric roof coatings are engineered with titanium dioxide pigments, resins, polymers, and fillers to create high-performance protective membranes. They provide for dirt resistance preventing dust and dirt build up. When dry, it forms a permeable membrane preventing the infiltration of liquids, but allowing the venting and evaporating of liquid. These coatings have no seams, and they are not mechanically attached to the roof in any way, and this type of roof coating fully adheres.
Temperature Control
Usually white, the elastomeric coating provides temperature control through its reflective properties and reduces up to 85% of heat from sunlight. The additional benefit of the heat reduction is that the building is cooler which helps keep cooling expenses down. The ultra violet protective properties reduce deterioration of the membrane. This ensures longer life not only for the membrane but also for the roof.
Elasticity and Durability
Elastomeric coatings expand and contract with roof dynamics caused by weather or settling. They adjust well to severe climactic conditions and bear up well under load and load changes. This type of coating also holds up to roof traffic and clutter from antennas and other equipment. Due to the polymer?s resistance to radiation effects, the coating ensures the integrity of the substrate. It not only prevents damage, but it also keeps the roof looking new longer.
These roof coatings are easy to apply and require no mixing. The application is easy as painting. Coating techniques include brushing, spraying, rollers and application by squeegees. They clean up with water, and no special chemicals are needed. They are non-toxic, and elastomeric roof coatings are non-volatile. The cost of this type of roof coating is attractive because of its long life, and its low maintenance requirements. The durability, tough weathering and energy saving properties of these elastomeric coatings make for an economical roof covering.
