Product Information
Ronseal One Coat Damp Seal can be applied straight onto damp. It'll seal it, permanently cover any damp stains and stop it damaging your paint. There’s no need for paint brushes so the clean-up is easy.
Make sure the room is nice and temperate, above 10°c. Open doors and windows for added ventilation and put down a dust sheet to protect the areas you don’t want to get paint on. It’s also important to remember that you should address the core problem of the damp before covering it up. If you just choose to paint over it, you won’t solve the problem and the damp will keep coming back. Before you start, prepare your walls for sealing. If damp has caused paint to flake and peel, sand it away so you have a smooth surface. If you notice any mould, use a mould killer to get rid of it. Shake the can until you hear it rattle and then keep going for an added minute. Hold it upright around 20-30cm away for the wall or ceiling and spray from side to side for an even finish. Wait 10 minutes for the first coat to dry. Apply a second coat and then a third, leaving 10 minutes between both. Once you have applied three coats, wait 24 hours for the seal to completely dry before you start decorating.
As this damp seal and not intended to be a top coat, it should be painted or wallpapered over. To clean the nozzle, just turn the can upside and spray for a few seconds. Then wipe the nozzle with a damp cloth.
- Dry in 10 minutes and ready to paint over in 4 hours
- Permanently blocks damp
- Protects paintwork
- No need for preparation
- Can be applied directly to damp surfaces
