Technoseal DPM is a ready-to-use, liquid damp-proofing membrane which provides a seamless, waterproof and radon barrier
Ideal to use as part of a below ground-level waterproofing system
Technoseal is SBR Latex-based liquid
Technoseal is a ready-to-use, liquid damp-proofing membrane which provides a seamless, waterproof and radon barrier, ideal to use as part of a below ground-level waterproofing system
Technoseal acts as a barrier against methane and carbon dioxide gases
It is safe to use in potable water and can be applied to pond lining as a waterproof barrier
Ideal for areas with constant water contact, such as under tiles in bathrooms, food processing areas and balconies.

Substrate Preparation:
The substrate should be smooth or have a light, even texture
Any masonry should be flush pointed and defects in existing surfaces made good
Ensure surface is clean, sound and free of dust, loose materials or surface water, but damp substrates are acceptable
It is sometimes advantageous to pre-wet concrete or masonry substrates before application
Test adhesion to substrate using a sample area before commencing application.

Mixing:
If necessary, the compound can be diluted with up to 10% water, however, care should be taken to ensure the correct dry coat thickness is achieved.

Single Coat Application:
If a single dry coat thickness of more than 0.3 mm is required, it is recommended that Technoeal be applied using airless spray
A single coat thickness of up to 1 mm is possible using this application method.

Two Coat Application:
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
The time scale for this will vary according to site conditions, but will typically be after 1 hour
The second coat should be applied within 24 hours
After all coats have been applied, the membrane should be left foor at least 4 days before attempting any bond tests.

Roof Applications:
Blistering can sometimes occur during this application process
This occurs when the heat from the sun causes a vapour pressure build up below the membrane
The problem is exacberated if the background conrete is wet
To minimise this risk and ensure a good bond to the substrate, the following should be undertaked
Vigorously brush the first coat into the background concrete using a stiff bristled brush
Prime the roof with a slurry of SBR Latex, if using roller, or an airless spray application method
Allow the slurry to harden for 2 days before applying Technoseal.

Wall / Floor Junctions:
In some situaions, e.g. at high stress points such as wall/floor junctions, it is beneficial to use polypropylene fabric (skrim) reinforcement
Choosing a suitable reinforcement it is possible to achive good control of the coating thickness
Choose a fabric with an approximate thickness of 0.5 mm
Roll the fabric into the base coat while wet.
Allow the first coat to dry to a tacky condition
Completely fill and cover the mesh with the second coat of Technoseal and a minimum thickness of 0.6 mm will automatically be achieved.

Conditions And Limitations:
Technoseal should not be applied when the temperature of the substrate, or the air temperature is below 7 degree C and falling
The dried film, like most organic coatings, is combustible and hence will not be suitable in all situations e.g. it should not be used to coat flammable materials (expanded polystyrene)
A minimum dried coat thickness of 0.6 mm is needed to provide a vapour barrier
This should be applied in a minimum of two coats
Incorporation of polypropylene fabric increases the tensile strength but decreases the extensibility.

Curing:
Touch dry within 1 hour the Initial cure within 24 hours and fullcure is 4 days.

Storage And Shelf Life:
Store in a sealed container, in temperatures between 5 degree C and 35 degree C, protected from frost and direct sunlight
Shelf life is 12 months when unopened, undamaged and stored correctly.
