Also known as liquid screed, this type does exactly as it says on the tin – it’s simply poured or pumped onto the floor and spreads out across the entire surface to achieve a level finish.
It’s quick and easy to use, and can help reduce the risk of unwelcome voids forming in the finished floor.
Most liquid products are made with calcium sulphate (as well as sand, water and various chemicals). The mixture is very quick to lay so it’s especially suited to large areas, but it will take a little longer to cure than dry screed.
You’ll also need to incorporate a vapour barrier directly below liquid products to ensure the floor insulation is protected from potential damage and that a “tank” if formed in order to prevent the material from escaping.
