Product Description

Centrecoat Armourcoat Epoxy DPM is a 2 part solvent free, liquid applied surface damp proof membrane and residual moisture suppressant.

Best Uses

Centrecoat Armourcoat Epoxy DPM is formulated for use as a coating over cementitious surfaces which possess high levels of residual moisture. This practice should only be adopted subject to a survey confirming adequate underlying ground stability. Moisture testing should be carried out in accordance with BS 8203.

Centrecoat Armourcoat Epoxy DPM permits early overlaying with vinyl, carpets and resin based products without the conventional "drying out" period being observed. This product is not suitable for use over underfloor heating systems.

After curing, Centrecoat Armourcoat Epoxy DPM provides a surface membrane with excellent adhesion to damp concrete and polymer modified sand/cement screeds. Hygrometer readings up to 98% RH as measured in accordance with BS 8203:2001 can be accommodated.

Centrecoat Armourcoat Epoxy DPM is available in red and yellow as a visual aid for application and coverage.

Application

The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm2) with a minimum pull off strength of 1.5 N/mm2.

Inadequate preparation will lead to loss of adhesion and failure. In coatings or flow-applied systems, there is a tendency for the finish to mirror imperfections in the substrate. Grinding or light vacuum contained shot-blasting is therefore preferred over planning where these types of finishes are specified. Percussive scabbling or acid etching is not recommended for any grade of resin flooring.

Movement Joints

Movement joints and cracks cannot be bridged with Centrecoat Armourcoat Epoxy DPM. These should be filled with a flexible jointing material.

Hydrostatic Pressure

Hydrostatic pressure may, under certain circumstances, cause adhesive failure between the flooring and the substrate. Where this is likely to occur, such as in areas where the ground water table is higher than the substrate, and where external tanking has not been applied, pressure relief must be provided e.g. by direct drainage. In new construction, for concrete bases in contact with the ground, a damp-proof membrane should be incorporated into the slab design, in accordance with the requirements of CP 102, in order to prevent ground moisture adversely affecting the resin flooring. In the case of basement floors in contact with the ground, the provisions of BS 8102 should be followed.

Centrecoat Armourcoat Epoxy DPM is a two component product. Fully drain the contents of the hardener component into the lightly coloured resin component and mix thoroughly with a slow speed electric stirrer fitted with a spiral paddle, for a minimum of 3 minutes until homogeneous.

Ideal ambient and substrate temperature is 15 - 25°C to achieve best results. Localised heating or cooling equipment may be required outside these parameters. The substrate & uncured floor must be kept at least 3°C above the dew point to reduce the risk of blooming or condensation on the surface for at least 48 hours after application.

Apply evenly using a notched trowel (1.5mm x 5mm V shaped) and flatten out the ridges with a pre-wetted out short pile roller whilst wet. Do not exceed the coverage rate of 4m2 per Kg under any circumstances. It is essential that each coat should be no less than 200 microns in thickness which should be checked using a wet film thickness gauge. Records of these measurements should be kept. Apply a second coat once cured at right angles to the first, It is essential that Armourcoat DPM is pin-hole free and continous with absolutely no gaps or cavities. If this is not the case, an additional coat should be applied. If a sand scatter is required for key or profile, this should be applied to a third coat of Armourcoat DPM.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
