About this Product
weberfloor DPM is a highly moisture tolerant, epoxy resin damp proof system, especially designed to bond to concrete surfaces even when the concrete is still drying out and containing a high degree of moisture.
weberfloor DPM is an effective moisture suppressant membrane for oversealing cementitious surfaces which contain high levels of residual moisture. New concrete or screed must be left for a minimum of 7 days before application of the membrane. Rough or uneven surfaces should be levelled before applying weberfloor DPM and this should be left a minimum of 24 hours to dry before applying the DPM. Power floated subfloors should be shot blasted before application of weberfloor DPM to assist adhesion.
weberfloor DPM permits early overlaying with vinyl, carpets and resin based products without the conventional 'drying out' period being observed for concrete bases.

Material Safety Datasheet
Preparation & Application
weberfloor DPM can be applied on substrates such as concrete and cement based levelling compounds. All surfaces must be mechanically sound, dry and clean,i.e. free from dirt, dust, grease or other contamination or coating. Laitance must also be removed from concrete.
Although weberfloor DPM can be used at lower temperatures, it is recommended that it is stored overnight at a minimum temperature of 15°C prior to mixing and application. In hot climates, store overnight in air-conditioned storage.
Pour resin into a clean, dry bucket. Add hardener and mix, using a drill and paddle, at a slow speed until a uniformly clear consistency is obtained.
Once mixed pour into roller tray to prolong pot life.
weberfloor DPM should always be applied in two coats.
Immediately after mixing, spread weberfloor DPM onto the substrate using a brush or roller. Spread the mix evenly and uniformly over the entire substrate.
The second coat should be applied after the first coat has partially cured; this is approximately 6 to 8 hours, depending on ambient temperature.
Apply the second coat evenly and uniformly at right angles to the first coat to ensure full coverage of the substrate.
Note: Do not leave the first coat longer than24 hours before re-coating.
Immediately after application of second coat cover weberfloor DPM in a full sand scatter,using 1 - 2 mm kiln dried sand.
After 12 hours, or overnight, the floor should be brushed and vacuumed to remove any loose sand particles.It should then be primed using weberfloor4716 primer and is then ready to receive a Weber levelling compound.
All equipment should be cleaned with webertec solvent before the material sets.
Packaging, Health & Safety
weberfloor DPM is supplied in 5.6kg packs.
Each pack contains:
1 tin containing resin
1 bottle containing hardener.
Storage and Shelf Life
Shelf life is at least 12 months when it is kept unopened, in proper storage conditions in a cool, dry area.
Contains epoxy constituents. Refer to information supplied by manufacturer (see Material Safety Data Sheet).
All skin contact with epoxy resin products should be avoided. Barrier creams should be used and operatives should wear protective clothing including gloves. Working areas should be well ventilated.
The hardener content is alkaline and labelled as corrosive. The resin content is labelled as an irritant. The flash point of all components is in excess of 100°C. In the event of fire use foam, dry chemical, carbon dioxide (CO2) or water fog extinguishers.
