Drybase Liquid-Applied DPM is a paintable damp-proof membrane that can be used in many situations including, but not limited to:
Drybase Liquid-Applied DPM is a ready-to-use product and does not require any extra components or ingredients to be mixed in. Just apply to any appropriate well-cleaned and laitance-free surface using a paint brush or roller.
Once applied, a coat of Drybase Liquid-Applied DPM will typically be touch-dry within one hour. This means that multiple coats can be applied in a single day to reach the specified loading of material. Depending on circumstances, two coats applied at right angles to each other is all that is required.
Drybase Liquid-Applied DPM is available in either black or white to suit your requirements. If ordered in black colour, it is dark blue when first applied but turns black when dry so you can see where it is ready for another coat or has become touch-dry.
As it dries, Drybase Liquid Applied DPM is tacky to the touch. If a screed is going to be applied or tiles laid then a final coat can be applied as a primer.

0 ReviewsEasy to work with and to apply. Time will tell as regards performance, but have every confidence it will provide an effective damp proofing barrier.
Very happy with my purchase - thank you.
Exactly as described, easy to apply, roller washed in water after, very happy
Excellent product, easily applied as per instructions with expected results
Went on easily and has worked effectively. Very pleased with my purchase.
Great for walls beneath external plank, we even used it on fences
Very good, so far, drys very quick, and little or no smells, I am still new to this product. Clive
Covers well. Needs two coats, other similar products need three. Brush clean in water, other similar products need white spirit. Shorter recoat time when compared to other similar products. Sadly does not smell very nice and a lot more expensive than similar products.
Used for garage wall base to floor base. Spreads nicely, used two coats as advised. Cannot judge effectiveness until winter weather arrives. Fingers crossed for any damp to be blocked. Could give information on storage life and how to clean brushes etc after. Found out later.
Hi Mark,
Thanks for your question. Around 2-3 as a general purpose DPM, depending on the substrate. If you require a Vapour Barrier, it will be more. Keep in mind that Drybase Liquid-Applied DPM does not provide a trafficable surface.
Please get in touch at 01403 210204 or email us at info@safeguardeurope.com. Our technical team will be able to advise you further about this specific project.
Bonjour, puis je utiliser ce produit pour mettre sur le carrelage de ma douche ? c'est juste sur une paroi. merci
Bonjour Cyril,
Merci pour votre question.
Nous ne recommandons pas la membrane d'étanchéité liquide Drybase pour cet usage.
Can Drybase Liquid DPM be used as a Radon gas barrier?
Drybase Liquid DPM can be applied to a substrate to provide Radon protection in accordance with BRE211 which states:
In areas with an increased radon potential, sufficient protection will be provided by a well-installed damp-proof membrane (DPM) modified and extended to form a radon barrier across the footprint of the building. This gas-tight barrier is known as basic radon protection.
Drybase Liquid DPM has been tested by Saarland University and was found to be Radon tight at 2 mm thickness.
To apply Drybase Liquid DPM for Radon protection, apply a minimum of 2 3 coats, allowing the previous coat to dry for an hour or so before applying the next coat. To achieve a 2 mm thickness the coverage of Drybase may be less than the stated 4.5 m² per 5 litres.
How do I apply a screed onto Drybase Liquid DPM?
The second coat of Drybase Liquid-Applied DPM can be used as a primer for cementitious levelling screed as long as it is applied while the second coat of Drybase Liquid-Applied DPM is still tacky.
Alternatively, create a mechanical key on the Drybase Liquid-Applied DPM layer by sprinkling fine washed sharp sand or kiln dried graded quartz sand while it is still tacky.
If both the first and second coats of Drybase Liquid-Applied DPM have already cured, a further coat can be applied to act as a primer for levelling materials such as cementitious levelling screeds. Any subsequent layers should be applied while the Drybase Liquid DPM is still tacky.
Can I lay tiling onto Drybase Liquid DPM?
Yes, however you will need to use be a polymer-modified tile adhesive.
Please ask the tile adhesive manufacturer for the thickness required and to ensure compatibility between the tile adhesive and Drybase Liquid-Applied DPM.
What thickness should a cementitious levelling screed be laid onto Drybase Liquid DPM?
Cementitious levelling screed should be laid at a thickness of between 50 and 70 mm or greater. Always take into account BS8204, the manufacturers guidelines and the required load bearing capacity.
If more than occasional foot traffic or commercial use is expected, we recommend that the cementitious levelling screed is laid as a thicker layer.
The surface of the cementitious levelling screed should be finished according to the type of wearing surface or flooring that is to be laid.
If the use of a thin sheet or tiled floor is required, then the use of a self levelling smoothing compound over the cementitious levelling screed should be specified.
Why can't I paint my garage / house wall with Drybase Liquid DPM?
Drybase Liquid DPM is not UV-resistant and will lose adhesion and disintegrate within approximately 12 months if applied externally due to UV light. It cannot be applied to vertical surfaces.
Why can't I paint an interior wall with Drybase Liquid DPM?
Drybase Liquid-Applied DPM does not have a strong bond to the substrate and will therefore not strongly adhere to vertical surfaces. It may also slump if applied to vertical surfaces, making it difficult to add any water based finishes like plaster or paint on to.

Hi, my garage floor is 16ft x 10ft how many 5ltr tins would I need? Thanks
