Coated Roofs
Problem
Common Problems:
Roofs with existing roof coatings can have the following problem:
Adhesion Loss: Improper installation or the presence of ponding water can cause the coating to lode adhesion.
Chalking/Cracking: Break down of the roof coating from wind, rain and UV exposure.
Biological Growth: Organic coatings can support the growth of fungus.
Why SRM over a Coated Roof?
SRM will restore and extend the life of your roof.
SRM is inorganic, and does not promote the growth of fungus.
SRM will perform and stay adhered in the presence of ponding water.
SRM protects the substrate from the UV attack and weathering.
SRM is a liquid applied directly to the roof system, covering every crack, gap and patch with a silicone product designed specifically for that part of the roof.
SRM provides a monolithic roof membrane − no seams.
SRM in white will provide a highly reflective, cool membrane.
WDG Products needed:
- 701 Sealant or 601 Butter Grade to seal the cracks
- WDG Polyester Fabric (if needed)
- KGF 1000 to seal around drains or scuppers
- HSS 535 Flashing Grade on walls, skylights, parapets, ect.
- HSS 535 Coating on the roof
Always perform an adhesion test prior to application of WDG SRM. 211 Primer may be required.
