Elastomeric coatings are very effective in resolving roof leakages
and can be used to restore virtually all types of rooftops. It has elastic
properties, and can stretch in the summertime heat and then return to their
original shape without damage. Elastomeric coatings usually contain polymeric constituents,
such as acrylic, and a white pigment, such as titanium dioxide, to make them dense
and reflective. An elastomeric roof coating is applied thicker than paint.
Types of Elastomeric Roof Coatings
1) Acrylic Elastomeric Coatings
This is most commonly used roof coating. Acrylic elastomeric
roof coatings may be used on sloped roof surfaces. The combination of durability,
easy clean up and environmental friendliness makes this coating the no.1 choice.
2) Butyl Elastomeric Coatings
This roof coating is for flat roofs such as asphalt built up
(BUR), modified bitumen (APP and SBS) and single ply roofing such as PVC and
TPO. It has water resistance and is ideal for applications requiring a vapour
barrier.
3) Polyurethane Elastomeric Coatings
These coatings are usually recommended for rubber roofs. It
may also be used on modified bitumen and single ply roofing such as PVC and
TPO.
4) Silicone Elastomeric Coatings
This coating is recommended for polyurethane foam because of
its exceptional weathering characteristics. Commonly used over newly installed
sprayed polyurethane foam and can also be used to recoat an existing silicone
coated roof.
