Wykamol Technoseal DPM Damp Proof Paint 5 Litre Black
Wykamol Technoseal DPM Damp Proof Paint Black is a ready-to-use, liquid damp-proofing membrane which provides a seamless, waterproof and radon barrier and is therefore ideal to use as part of a below ground-level waterproofing system.
Wykamol Technoseal DPM Damp Proof Paint 5 Litre Black
Wykamol Technoseal DPM is an SBR latex based liquid damp proofing paint for water proofing applications. The paint dries to form a tough semi-gloss finish. Can be applied to walls under render or plaster as a water barrier.
Advantages:
- Single pack system
- Water based compounds that can be applied even to damp backgrounds
- Non-toxic, non hazardous, solvent and plasticiser free
- Gas barrier for carbon dioxide, methane and radon
- Toughness, high flexibility, extensibility and good crack bridging properties
- Low water vapour permeability
- Alkali resistant, can be applied to alkaline surfaces
- Resistant to silage acids
- Non staining
- Quick drying. Typically touch dry in 1 hour
Technoseal Applications:
- Floors: Under/above screeds to provide a damp proof membrane.
- Basements: As part of a waterproofing system beneath ground level.
- Walls: Can be used under render or plaster as a water barrier or vapour barrier.
- Tiling: As secondary protection under tiles in wet areas e.g. bathrooms, food processing areas, balconies, etc.
- Water Storage: The membranes perform well in our tests even when continuously immersed in water.
- Silage Storage: The membrane protects concrete from silage attack. It also acts as a barrier against the gases methane and carbon dioxide.
Coverage: A minimum dried coat thickness of 0.6mm is needed to provide a vapour barrier. This should be applied in a minimum of two coats.
For the final dried membrane thickness of 0.6mm a coverage rate of 1.20kg/m2 is required (this is the total for all coats). This corresponds to approx 1 litre/m².
Colour: Black
Also available in White. See: Wykamol Technoseal DPM Damp Proof Paint 5 Litre White
Note: The colour of the liquid compound will differ slightly from the colour of the dried membrane. The colour shade may vary batch to batch. The membrane dries to a tough semi-gloss finish.
Size: 5 Litre

Wykamol Technoseal DPM Damp Proof Paint Black Usage Instructions
The background surface should be smooth or have a light even texture. Any masonry should be flush pointed and defects in existing surfaces made good. The surface needs to be clean, sound and free of dust, loose material or surface water.
The membrane should not be applied in wet conditions or where these conditions are likely to occur before the membrane has dried. The membrane should not be applied when the temperature of the background, or the air temperature, is below 7°C.
It is sometimes advantageous to pre-wet concrete or masonry backgrounds so that these are damp but free from any water glistening on the surface, to aid the wetting out of the background.
Because of the wide variety of background types and siteconditions it is always advisable to check adhesion to the background by testing on a sample area before starting any job.
Application: The membrane may be applied by brush, roller or airless spray*. If necessary the compound can be diluted with up to 10% water. However, care should be taken to ensure that the correct dry coat thickness is applied.
The thickness of the dried membrane per coat depends on the method of application. For a single dry coat thickness of more than 0.3mm it is recommended that the membrane be applied by airless spray. If airless spray is used, single dry coat thicknesses of up to 1mm can be obtained. (Note: A single coat of 0.6mm dry thickness or more will require a greater drying time than for an equivalent multicoat application.
* (e.g. “Aro” gun, model 651533, on a “Clemco” pot. Compressed air supply pressure 5.6N/mm2 (800psi) and compression ratio 28:1. Tip size 0.64mm (25/1/1000”). Fan width 200mm (8”).
If two coats are being applied it is recommended that the coats be applied at right angles to each other. Before applying the second coat it is necessary to let the first coat become touch dry. This will vary according to site conditions but will typically be in the order of 1 hour. The second coat should be applied within 24 hours.
After all coats have been applied, the membrane should be left for at least 4 days before attempting any ponding tests. Under unfavourable drying conditions this period may need to be extended. Whilst most applications to concrete roofs have been successful, blistering (shortly after application of the membrane to the roof) has occasionally occurred. This blistering is caused by the heat from the sun causing a vapour pressure build up below the membrane. The problem is exacerbated if the background concrete is wet. The risk of blistering can be minimised by ensuring a very good bond to the background and avoiding application of the membrane in, or shortly prior to, strong sunlight. Techniques for maximising bond are:
a. Vigorously brush the first coat into the background concrete using a stiff bristled broom.
or
b. Prime the roof with a slurry of Wykamol SBR latex and Cement. Allow this slurry to harden for 2 days before applying the membrane.
In some situations e.g. at high stress points such as wall/floor junctions it is beneficial to use polypropylene fabric (skrim) reinforcement. By choosing a suitable reinforcement it is possible to achieve good control of the coating thickness i.e. by choosing a fabric approximately 0.5mm thick and ensuring that the mesh is completely filled and covered, the minimum coating thickness of 0.6mm will be automatically achieved.
The incorporation of fabric usually increases the tensile strength but decreases the extensibility. The fabric is rolled into the wet first coat, and then coated with additional membrane after allowing the first coat to dry to a tacky condition.
