Rated 5 out of 5 by from Excellent Product " Surprisingly easy to apply. I used a roller and obtained a good solid smooth coat. I was very impressed with the final result. Good and solid in a few hours and proved to be an excellent base for emulsion. The only warning on this is that the stated coverage is somewhat optimistic. I used 2.5 litres to cover a 5m wall. That's about 5m² per litre, not the stated 7m². Certainly did the trick though and was well worth the expense. No sign of any marking to date ( now four years later ). This is an excellent, easy to use product. "

Rated 5 out of 5 by from Was'nt at all sure but...... So far so good for rectifying damp/mould in cupboards and wall,all due I believe through lack of ventilation by tenants never opening a window. Although this paint is pricey its better to pay more for something that works instead of something which is cheap and doesn't last . Its not the easiest paint to apply,but a decent brush is needed.

Rated 1 out of 5 by from Damp patch all sorted Damp patch appeared on wallpaper due to external leak. Needed to redecorate in a hurry but couldn't get a builder to sort the leak in time, so bought a tin of Thompson's One Coat Damp Paint. next day – patch sealed nicely and able to redecorate straight away. Brilliant product!

Rated 5 out of 5 by from Brilliant with a roller Thompson's advised not using a roller with their One Coat Damp Seal as it was difficult to clean afterwards,though,I didn't mind throwing the roller sleeve in the bin if it cut down on painting time. I can report that this Damp Seal worked well using a roller,completely covering a magnolia colour with just one coat.(It may take 2 coats if covering a darker shade). My advice is to buy a roller which comes with spare sleeves and it will save a good deal of time. The One Coat Damp Seal?, Brilliant !!!

Answer: 
Thank you for your enquiry.
This product will not address your issue of mould, Thompson's One Coat Damp Seal is designed to cover residual stains caused by mould/damp issues that have been addressed and resolved.

Thanks for your question. If the source of the damp has been eradicated and it is now just the stains coming through then Damp Seal will stop these spoiling any subsequent decoration. If the source of damp is still present Damp Seal won't solve the problem.

Can the damp seal be painted as the first coat on new dry plaster or does a mist coat of emulsion need to be applied before the damp seal?

Answer: 
Thanks for your question. This product is a damp stain blocker so it shouldn't be required on new plaster and therefore I would advise against it use on this occasion.

Answer: 
Thanks for your question, yes that is fine but the One Coat Damp Seal is a base coat so you will need to emulsion over afterwards, allow 4 hours before applying the emulsion.

Answer: 
Thanks for your question. The One Coat Damp Seal will not prevent penetrating damp, it is used once a damp problem has been eradicated to prevent damp stains from spoiling subsequent decoration. Thompson's Water Seal could be used on the outside of the wall to achieve this provided the outer face of the wall is not painted.
