Product Information

Make sure the substrate is load-bearing and that any laitance is removed mechanically (common on new concrete floors/screeds). You can then apply the first coat with a roller. Once touch dry, the second coat should be applied at right angles to the first. How to apply Liquid DPM to walls

Yes, you can screed over Liquid DPM but we recommend the second coat is touch dry before applying a screed. If more than 72 hours have passed since the second coat was applied we suggest a third coat is applied as a primer for the screed. Can you tile on a Liquid DPM? We recommend two coats are applied for all purposes. All subsequent coats should be applied at right angles to the previous coat. Before applying a second coat, allow the first coat to become touch dry. This is typically within one hour. The second coat should be applied within 24 hours of applying the first coat. Once the second coat is dry, you can render over it. Whilst you can tile directly onto a Liquid DPM, it may be wise to consider installing an decoupling membrane over the top. We suggest you speak directly with your tiler for more information. Can you paint over Liquid DPM? DPM: 100-250 g/m 25 to 50 square meters per 5 litre depending on surface per coat, with total rate at least 400 g/m 2 to 3 coats.

Yes, Liquid DPMs can be painted over with standard water-based emulsions. We do not recommend they are overcoated with Epoxies. If this is a requirement then we suggest you use an Epoxy DPM first. Can you plaster over Liquid DPM?

Make sure that all surfaces are clean, free of debris and any previous coatings. All existing defects should be repaired. A primer is not required but you can dampen the surface first to help adhesion. How to apply Liquid DPM to concrete floors
