Blackfriar Interior Seal Damp is a clear coating which prevents damp patches from spoiling interior decoration. Formulated for use on surfaces such as plaster, brickwork, cement and mortar. Penetrates and seals surfaces against damp.
Preparation
Ensure surface to be coated is clean, dry, sound and free from wax, grease or any other contamination. Mould growth should be treated with Blackfriar Anti-Mould Solution and allowed to dry.
Application
Stir thoroughly prior to use with a broad stirrer. The product may be applied by brush, roller or spray. Apply at least two coats, lightly rubbing down between coats to prepare the surface for subsequent redecoration. Be sure to apply the product 300mm beyond all sides of the dampness.
Thinning
Not recommended.
Limitations
Do not use under cold (less than 5°C) conditions. This product will not cure the source of penetrating damp - the cause of persistent damp should be cured before applying Interior Seal Damp. Not for use over wallpaper. Will not cure efflorescence. Do not apply to wet surfaces. Application onto damp surfaces will prevent full penetration into the surface and prolong the drying time of the product.
Drying Time
Touch dry in 2 - 4 hours. Recoat after 16 hours and within 3 days. Drying times are based on an ambient temperature of 20°C and 50% relative humidity. Lower temperatures or higher humidity will prolong the drying and overcoating times.
Clean Up
Remove as much product as possible from application equipment before washing with white spirit. Do not empty into drains or water courses. Some local authorities have special facilities for the disposal of waste coatings.
Storage
Store in a dry, safe place. Do not store in environments where extreme temperatures may occur. Keep within 5 30°C. Do not store in direct sunlight.
Features
Protect interiors from damp
Use on plaster, brick & cement

Water is penetrating my brick wall from the outside to the inside. I am unable to apply any form of brick sealing the outside. Will Interior Sealant stop water seeping through the brickwork?
Answer:
For exposed interior brickwork or blockwork you can apply Zinsser Watertite but this must be applied to bare substrates only. If the issue is not resolved on the outside of the brickwork though, no coating will last on the inside.

Question:
Will your paint prevent black marks appearing Problem down to condensation
Answer:
Blackfriar Interior Seal Damp would not prevent mould. The best product would be Zinsser Perma-White Interior to resist mould however excessive condensation will form on the surface and can leave slight marks, (clear marks not black). Another good option would be Zinsser AllCoat Exterior (Water Based) Satin or Matt - these are less likely to leave any marks. Treat the mould first then apply 2 coats of one of the above products, surfaces must be completely dry before applying any paint coating.

Question:
Hi, Can this be used as a top layer on an already painted wall?
Answer:
Blackfriar Interior Seal Damp should be applied to bare plaster. If applied to a painted wall which is damp the paint may blister up behind the Seal Damp. It will be best to sand off the paint in the damp areas before applying the Seal Damp.

Question:
Can this be used on an interior bathroom with real bricks & stone.the bricks are fine but the stone is flaking away Badly . will this product prevent that.
Answer:
Blackfriar Interior Seal Damp will darken the colour of the stone, if this is OK then brush the stone well to remove as much dust as possible, thin the first coat of the Blackfriar Interior Seal Damp with white spirit to act as a sealer coat, followed by 2 further coats.
If a clear non-darkening product would be preferred then the Blackfriar Quick Drying Varnish would probably be OK depending just how friable the stone surface is, brush off the loose material as above. Thin the first coat of the varnish with water then 2 full coats.

Question: Can the black friars paint be used on already damp walls that have penetrated ordinary emulsion on new plaster.
Answer:
Blackfriar do say to apply the Interior Seal Damp to bare plaster however you can lightly sand the paint finish with the damp marks showing then apply the sealer. 2 coats can be applied then overcoated with your emulsion paint.
This product will only hold back minor damp problems, if there is a constant damp issue this should be resolved.
