Palace Chemicals One Coat DPM can be laid over a wide range of substrates including concrete, sand/cement screeds, anhydrite and calcium sulphate screeds.1 Coat DPM is ideal for use as a damp proof membrane where the residual moisture content in a new or existing screed is up to 98% relative humidity (RH). 1 Coat DPM can also be used to protect screeds laid on damp floors where no pre-existing damp proof membrane is in place or where the structural damp proof membrane is ineffective. Once cured, 1 Coat DPM produces a membrane which can accommodate hygrometer readings up to 98%RH on cement-based screeds & still demonstrate bond strength issues. Palace Chemicals One Coat DPM has good resistance to water, grease, oil, dilute mineral and organic acids.
Under ambient conditions, 1 Coat DPM is ready to receive a smoothing compound as soon as 4 – 5 hours after application. If the applied DPM is still very tacky, this
indicates that the DPM has not fully cured and additional curing time should be allowed before covering with a levelling screed.
Approximately 2-2.5m²/kg depending on application and substrate conditions to give a finished thickness of approximately 250-300 microns.
NOTE: It is essential that the applied 1 Coat DPM achieves a 100% continuous film free from pinholes, or gaps, which can occur on porous screeds for example, in this case an additional application, may be necessary.
Movement Joints: Any joints in the floor such as movement joints, must not be bridged using 1 Coat DPM since they will require treatment using a flexible impervious jointing system and be carried through to the floor finish.
