Proflex Floorprep Fastrack DPM 5ltr
Proflex Floorprep Fastrack DPM is a ready-for-use, one part, water-based moisture vapour suppressant. Each 5kg tin covers approx 25m2.
KEY BENEFITS SUMMARY
Designed to work as a DPM/moisture vapour suppressant prior to the application of a full coverage of Proflex adhesive.
Water based, low VOC compliant, non-hazardous.
Easy to apply – generally primerless* application and single component, no mixing required.
Suitable for heated concrete and sand cement screeds (provided the surface temperature does not exceed 27°C in accordance with BS 8203 and BS 5325).
Extremely fast drying – as quick as 30 minutes, depending on environmental conditions.
Usage / Purpose
When used as directed, the product is a surface moisture vapour suppressant developed to suppress residual construction moisture and rising damp in cementitious subfloors including power floated concrete and sand/cement screeds. Consideration should be given to the fact that if a self-levelling compound is required it will be below the DPM layer and should be suitable for this environment. Do not lay self-levelling compound over Fastrack DPM.
Not recommended for application onto Gypsum based screeds, Anhydrite (calcium sulphate), bitumen or resin subfloors. *Floors which are dusty, or excessively dry must be treated with a suitable primer (Floorprep Surface Binder) before using Fastrack DPM.
Colour
White emulsion when wet, becoming blue/grey on application, translucent when dry.
Packaging
5 kg plastic jerricans.
Composition
Floorprep Fastrack DPM is a modified synthetic polymer emulsion.
Performance
(Typical Values) CURE TIME (at 20°C) Approximate 1/2 hour.
USAGE GUIDELINES
Standards
All aspects of the installation must be in accordance with the requirements of BS8204, BS8203 (Installation of Resilient floorcoverings) or BS5325 (Installation of Textile floorcoverings) and supplementary specifications and BS8201.
Moisture Testing
(in accordance with British Standards8203) Hygrometer readings must be taken and recorded. The sealing effect of concrete curing compounds and over-trowelled concrete will extend the time taken for the hygrometer to reach equilibrium. Subfloor measurement readings of up to 97% RH (measurable) can be accommodated with the system of Proflex Fastrack DPM and a full surface covering of Proflex Ultra Adhesive. (97% RH equates to approx. 8.5%MC in sand/cement screed and 6%MC in concrete)
Conditioning
Condition the contents by storing for 24 hours at +15°C to +25°C as cooler temperatures will increase viscosity and make application more difficult. Higher temperatures will speed the chemical reaction and therefore reduce working pot life.
Surface Preparation
Ensure the subfloor is clean, sound, surface dry and free from contaminants that may prevent adhesion. All dust and plaster deposits must be removed and vacuumed. Remove all surface water. Highly polished surfaces or concrete containing a curing agent or surface hardener may require shot blasting. Power floated concrete must be abraded or shot blasted to provide a good key for adhesion.
Priming
In most circumstances no priming is required. For floors with excessively dry and absorbent surfaces, or floors that are dusty/burnt, a primer (Floorprep Surface Binder) will be required. Always test a small area first to confirm suitability.
Method of Application
Note: drying times are based on ambient conditions, and will be slower in cold and/or wet conditions. Good ventilation is essential. Shake the bottle to mix contents immediately prior to use. Pour into a rectangular bucket or paint tray and apply with a medium pile roller. It is essential that a pin-hole free coating is achieved and to maintain a coverage rate of 5 m² per kg per coat. (i.e. 5 kg unit covers 25m²). The overall dry film coating thickness should be a minimum of 150 microns. Do not over-apply. Always apply about Fastrack DPM up the walls to a height of approx two inches above floor level as a precaution. Allow to dry to a translucent film. At 20ºC the drying time will be approximately 30 minutes, depending on the subfloor and other environmental conditions. Once dry, it is advisable to begin application of the Proflex Ultra Adhesive as soon as possible, to prevent surface contamination. Always apply the adhesive within 2 days after application.
Coverage
Approx. 25m² per 5 kg unit.
