Shower Solutions recommend that any repair work to walls should be completed by a professional. However if you are up for the challenge then read below, we have explained briefly what needs to be done.
Make sure you allow a least six months for the walls to dry completely out before attempting to repair the damaged walls.
Scrape off all the damaged surfaces on the walls, like peeling paint, dry bubbled areas and any deteriorated plaster straight after we leave. This will help your walls dry faster. If you just leave the walls to dry on there own it will take longer to dry as any paint on the wall will retain moisture.
When it comes time to repair the walls allow a few days to complete the process because applying a coating of any product over a slightly wet surface will cause further damage.
Sand back the problem areas, then fill with new plaster. Once the new plaster is dry sand back that as well so you are left with a nice straight wall again.
Apply a wall primer to the damaged areas letting it dry completely. Repeat the coating to ensure the surface is primed.
Once all the above steps are completed you are then safe to re paint your walls again.
