Sika SikaBond Rapid DPM (Damp Proof Membrane) Liquid, 5 Litre

Product Information

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. applied using a simple application gun this sealant gun is used to inject the cream barrier into a series of holes drilled into a mortar course. Compatible with all SikaBond® wood floor adhesives. Especially suited to refurbishment projects where old adhesive residues are present. 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.

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?

Ready to Use and Easy to Apply

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: Surface conditioner/ primer: 1 coat, 100-200 g/m 25 to 50 square meters per 5 litre depending on surface. 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

Sika SikaBond Rapid DPM (Damp Proof Membrane) Liquid is a rapid drying, single part moisture curing polyurethane. SikaBond Rapid DPM is used for the priming and sealing of absorbent and non absorbent subfloors, the consolidating of weak cement screed and isolation of old adhesive residues. SikaBond Rapid DPM can be used as a Damp Proof membrane on subfloors not under hydrostatic pressure, and can be used over underfloor heating. SikaBond Rapid DPM is compatible with all SikaBond Wood Floor Adhesives and is especially suited to be used for refurbishment projects where old adhesive residue is present. Does not require a special, expensive pump only a strong sealant gun such as our HD Pro Sealant Gun Isolator for adhesive residues: 1 coat, 100-200 g/m 25 to 50 square meters per 5 litre depending on surface.

HOW ARE MY ITEMS DELIVERED?

Absorbent and non-absorbent sub-floors, consolidating weak cement screed and isolation of old adhesive residues. 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? 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 When applying PermaSEAL Liquid DPM to walls, we recommend a sandwich system method. This is where you chip off the existing render and then apply the Liquid DPM before applying new render or plaster.

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 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. 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 wallsDPM: 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. Low hazard, water-based product non-caustic, non-flammable and not injected under pressure with very low wastage

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