I would like to “compare and contrast” some different tapes for use on the rough surface of exterior grade plywood – for air sealing purposes.
The tapes under my consideration at the moment are:
1. Grace Vycor Plus
2. Berry Plastics Barricade OptiFlash 732-20
3. Mastic tape
4. Siga Rissan
All four tapes claim “agressive” adhesion.
Adhesion is one thing, conforming to the slightly irregular surface of plywood is another.
I only have direct experience using mastic tape but I can imagine that any of the first three will probably adhere and conform well.
The “Rissan” is a mystery.
A Siga brochure indicates that it bonds to “wood”.
It also says that some difficult substrates require priming with “Dockskin”.
I wonder if plywood is a difficult substrate?
Anybody ever tried Siga Rissan on plywood?
