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 Our Liquid DPM can be used on walls under a render to create a flexible waterproof layer. It is not suitable for applying to plaster. Once cured, the membrane provides protection against penetrating damp, allowing you to decorate with confidence. Applying a Liquid DPM Absorbent and non-absorbent sub-floors, consolidating weak cement screed and isolation of old adhesive residues. PermaSEAL Liquid DPM protects floors and walls from moisture in just two coats. All you need to do is brush or roller it straight from the tub on to a sound, clean masonry surface to create a flexible damp proof and vapour proof layer. Our Liquid DPM paint that can be applied above and below screeds to provide an elastic damp proof membrane for floors. When applied on top of screed, it needs to have a further coating to protect it from damage such as laminate, tiles, vinyl, wood and carpets. PermaSEAL Liquid DPM can also be applied to concrete floors below screeds. Liquid DPM for Walls

Once injected to the mortar course,the sikamur injecto cream 100 will diffuse within the damp wall to form a water repellent barrier ie a damp-proof course,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. Isolator for adhesive residues: 1 coat, 100-200 g/m 25 to 50 square meters per 5 litre depending on surface. 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? 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?

In warm conditions the Liquid DPM can be touch dry and recoatable in just one hour. In colder damper conditions this can be longer. Can you screed over Liquid DPM? Where under floor heating is incorporated into the sub floor the heating must be turned off for at least 48 hours before, and until after, tiling.

Does not require a special, expensive pump only a strong sealant gun such as our HD Pro Sealant Gun

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 Wherever possible, very damp walls should receive an external treatment such as waterproof render/masonry paint etc. If this is not possible, the following procedure may benefit - although it must be emphasised that only adequate external treatment will cure the most severe conditions.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? 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. Compatible with all SikaBond® wood floor adhesives. Especially suited to refurbishment projects where old adhesive residues are present.

We recommend two coats are applied for all purposes. All subsequent coats should be applied at right angles to the previous coat.

Uses of Liquid DPM

If a condition of rising damp exists, the best form of treatment is the insertion of a damp proof course. Where dampness is due to penetration of the wall, proceed as follows:
