DCP Strongcoat OT DPM

Description

DCP Strongcoat OT DPM is a two pack, solvent free, oil-tolerantepoxy based damp-proof membrane for use with the DCP range of surface coatings and toppings.

Ideal for environments susceptible to oil contamination, Strongcoat OT DPM suppresses residual construction moisture and rising dampness in concrete and sand/cement screeds and can be used in situations where the relative humidity level is above 75%. It is applied by brush or roller in one or two coats depending on the relative humidity of the floor.

COVERAGE
Strongcoat OT DPM is applied at a coverage rate of 3.5 – 3.7 m²/kg to achieve approximately 200 micron DFT per coat.

SUBSTRATE PREPARATION
The substrate must be clean, dry, even, dense and free from oil, grease, dust and other contaminants. A clean surface will ensure maximum adhesion between the substrate and the coating. Concrete floors must have a minimum compressive strength of 25 N/mm².

SURFACE PREPARATION
Ensure that all pinholes and grooves in the prepared substrate are properly filled using suitable epoxy putty materials prior to the application of subsequent layers.
This is crucial to prevent pinhole reflection and to achieve a smooth, seamless finish.
Unsound layers and contaminated concrete surfaces must be prepared using mechanical surface removing equipment. Acid etching can be used only in well ventilated areas. Areas deeply contaminated by oil or grease should be treated by hot compressed air.
