  • Our Stain Block Damp Seal is tough on damp. It'll permanently seal and remove damp stains and is over paintable in just 4 hours.

    • Suitable for use on: All interior walls & ceilings

  • Preparation: It's important to make sure the cause of damp has been sorted before painting, otherwise it'll just come back. Open doors & windows to make sure the room is well ventilated. Remove any wallpaper and get rid of flaking paint with a damp cloth. Fill any cracks or holes, if needed. You can apply this onto damp surfaces, just make sure they're not dripping wet.

    Application: Give the tin a really good stir. Apply with a brush or roller, whichever you prefer. Apply the paint over the affected area, plus about 30cm around it. Wait 4 hours before applying a second coat.

    Clean up: Clean all your equipment with white spirit.

returned- for now
Style: Updated Formula
I was using the lotion version of this for about a year, then went to the balm for more hydration. However, it seems to be breaking me out. I think because it's spring, im not needing as much occlusion as i did during winter. I'm gonna go back to the lotion formula, then pick this up again next winter. It is a little hard to spread, but I spray the avene mineral water on, let it dry slightly, and press the balm into my skin when its still wet. That helps thin the balm just enough to rub in. Otherwise, it can actually feel kind of rough!

Impressive
Style: Updated Formula
Nice thick cream! I even saw results (skin improvement) within days. I like this way better than their Cicalfate+, as it’s easier to rub in, less greasy, and doesn’t have the water vs cream separation issue. I’m not a huge fan of the pump top for this one, but at least it’s a tube instead of a solid canister (where you can’t see how much is left or get to the last bit).

Not Hydrating Enough
Style: Updated Formula
Non greasy but is not moisturizing enough for my dry eczema prone skin.
