I just finished applying Redgard on two walls I need to clean up the roller and the brush ...how do I do that ? Acetone based solution ? Any other dissolvent?

    what are the cleanup instructions on the product container?

    Please don't feel like questions are unwelcome. I think the people nudging you toward "read the instructions" are more concerned with your legal obligation to follow the instructions. on products like these, it's legally mandatory to follow the instructions. (which requires you read them obviously). Nov 21, 2021 at 19:05
  • not a problem ...I did read that but somehow I missed that line. Discovered that by accident :-) (trial and error)

From the technical data sheet:

Cleaning of equipment

Clean tools and hands with water before the material dries. Clean all spray equipment immediately after use.

Which to me means: If you don't do it right away, the work involved to clean it is probably more than the rollers and brush are worth. But I could be wrong.


Turns out that immersing the brush and the roller in water solves the problem, it will disolve if it still soft/wet
