3M SD650 Flat Roofing System Videos

3M SD650 Over Asphalt

This shows how we apply the two coats of SD650 over an old asphalt roof, after it has been cleaned.

3M SD650 Around Details

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.

Preparation Before 3M SD650

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.

3M SD650 Test

We test the 3M SD650 roofing materials underwater. Because the material is moisture-cured, laying it underwater is possible, as this demonstration proves.
