HQC Anti-Mould Additive 100ml Concentrate – Add Long-Lasting Mould Resistance to Paint, Wallpaper Paste & Grout – Prevents Black Mould for Up to 5 Years Without Affecting Paint Finish

Easy to add to paint, doesn’t effect the paint at all, only done a week ago but so far so good there are 5 people showering every day in this house and my kids like to spend a very long time in the shower so the mould arrives quickly but nothing at all in 7 days.

Easy to use & mix. Good value as 1 does 5L of paint & doesn't effect the quality of paint finish or coverage.

We had a massive amount of white paint for ceilings etc in our new house. We decided to do our whole bathroom in the basic white till we renovate and as such used that non-specific paint but added some of this to it. Very easy to use for sure, just get your numbers right for the fill effectiveness. We didn’t notice it made the paint have any smell, didn’t affect coverage, didn’t impact quality of the paint, didn’t affect the thickness of the pant in any way. We’ve now lived here over a year and we’ve had no problems at all. We don’t have an extractor fan (2 large windows) so the room does get very steamy at times (especially in the winter) and in the week leading up to painting it we had already noticed mould on the ceiling. Once cleaned then painted over it’s gone and never came back again. So I definitely recommend and for the price it’s great value.

Ok but came back

Good product

Definitely recommend. Definitely works keeping that horrible black mould away. Follow the instructions and clean up the wall first. I've not seen black mould in my flat and I live in Cornwall by the sea so it's damp or winter not seen black mould since I've been using it. Just well mix in to quality paint

Easy to use. Good value.

Added to paint, few months have gone by, no mould. Guess it's working 💪
