Drybase Liquid-Applied DPM

  • Bitumen-free & water-based

  • Easy to apply (ready for use)

  • Effective gas barrier

  • Quick-drying & strong bond

Drybase Liquid-Applied DPM is a paintable damp-proof membrane that can be used in many situations including, but not limited to:

Application of the Drybase liquid DPM to the floor using a roller.

Ready for Use and Easy to Apply

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.

A contractor applies both coat of Drybase LDPM. 1st coat: horizontal. 2nd coat: vertical.

Quick-Drying 2-Coat Application

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 LDPM black and white image comparisons

Available in Black or White

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.

Ideal Primer for Screed or Tile Adhesive

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.

Customer Questions

Jan Wolfe

Can this be used for tanking a wet room and be (ceramic) tiled over ?

Mollie Brown at Safeguard

Good morning Jan,

Thank you for your enquiry.

Drybase Liquid Applied DPM would not be suitable for this application. It is recommended for use on concrete flooring and also floor to wall joins up to the height of the damp proof course.

I hope this helps, if you have any further queries please do not hesitate to get in touch with us directly.

Kind regards,

Mollie
Safeguard Europe Ltd

Kevin Riddell

Would this be suitable to use on top of plywood subfloor to make waterproof in a bathroom before vinyl tiles are installed?

Jack Harding at Safeguard

Good Morning Kevin

Thank you for your question.

Drybase Liquid Applied DPM should be applied to the bare concrete slab itself and not onto any other surfaces. It then should be protected by usually a screed or underlay, you should not apply vinyl tiles directly over the top of this.

If you have any further questions please contact us on 01403 210204 or email us at [email protected].

Kind regards

Jack

Paul Holmes

can you plaster over the liquid dpm and is so what plaster do you use - normal or renovating

Safeguard Europe

Hi Paul,

Thanks for your question. We don't recommend you paint a full interior wall with Drybase Liquid DPM, as it can slump and is not compatible with plaster finishes.

Please get in touch via 01403 210204 or email us at [email protected] for more in-depth advice about your project.

Mark Mcginnis

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

Safeguard Europe

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 [email protected]. 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

Safeguard Europe

Bonjour Cyril,

Merci pour votre question.

Nous ne recommandons pas la membrane d'étanchéité liquide Drybase pour cet usage.

Safeguard Europe

Can Drybase Liquid DPM be used as a Radon gas barrier?

Safeguard Europe

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.

Safeguard Europe

How do I apply a screed onto Drybase Liquid DPM?

Safeguard Europe

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.

Safeguard Europe

Can I lay tiling onto Drybase Liquid DPM?

Safeguard Europe

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.

Safeguard Europe

What thickness should a cementitious levelling screed be laid onto Drybase Liquid DPM?

Safeguard Europe

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.

Safeguard Europe

Why can't I paint my garage / house wall with Drybase Liquid DPM?

Safeguard Europe

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.

Safeguard Europe

Why can't I paint an interior wall with Drybase Liquid DPM?

Safeguard Europe

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.
