Paint removal speedheater paint remover. First posting

The Rotex or RAS 115 does a pretty good job removing latex if you use the lowest grits of Saphir sandpaper.  I've seen huge improvements with the RAS when using Saphir 24 grit and a sander setting around 3.  Overall, latex is a pain and sometimes a hand held scraper is the ticket (don't overlook a good scraper) as the latex will often just sit on the surface and can be peeled away with some ease.  After restoring the  40 or so sashes that I have, I'm convinced that latex, especially thick layers of latex, is one of the main reasons for wood rot.  Latex seems to give no penetration, sitting on the wood, and water ,if it can work its way through cracks in in the paint, just stays behind the paint film with bare contact to the wood --- all types of fungi and mold love it in there and begin the rot.

Moreover:    Latex with latex primer seems to cause greater problems than latex with oil based primer.

Very true!

Good to hear you agree Mike --- I'm thinking Latex paints have been a big help to the epoxy repair suppliers.
