3M SD650 Test.
The 3M™ Scotchkote™ Urethane Roof Coating SD 650is one of the best liquid flat roofing systems on the market. In this video I show you just how strong the membrane is.
This shows how we apply the two coats of SD650 over an old asphalt roof, after it has been cleaned.
Liquid roofing systems are very good for dressing around details and hard to get to items, such as pipes and skylights. We can also encapsulate walls and flashings.
Because of the cost of stripping an old roof, overlaying with the 3M SD650 system becomes a very attractive alternative. I show what kind of preparation is needed, and the first coat being applied.
I test the 3M SD650 roofing materials underwater. Because the material is moisture-cured, laying it underwater is possible, as this demonstration proves.
