Q. My walls are bubbling, what is the cause of this and how to fix it?
Limewash and Prep Coat are not a cause for bubbling. The cause of bubbling is usually due to the underlying wall and wall preparation:
- Plaster or plaster patches that have not had enough time to dry and cure.
- Repair materials containing solvents and VOC's
- A solvent-based primer that has reacted with the underlying wall
How to fix and repair Bubbled (internal) Limewash Paint Surfaces:
1 Sand back any affected areas
2 if possible allow time for more off-gassing
3 then start the process of painting again, with the correct water-based primer/sealer, then
4 apply 1 coat Bauwerk Prep Coat and
5 apply 2 coats of limewash paint.
