Description Ultra Floor DPM IT Rapid Damp Proof Membrane is a two component, solvent free epoxy resin system for use as a surface damp proof membrane (DPM) and as a screed bonding aid (primer) for industrial flooring applications. It is supplied in a twin pack dual chamber to enable ease of transport and mixing. The product performs by a reaction between the resin and hardener components to give a durable continuous membrane. When mixed the Ultra Floor DPM IT Rapid Damp Proof Membrane is a black colour enabling easy identification of applied areas. Available in 5kg and 10kg container sizes. Ultra Floor DPM IT Rapid Damp Proof Membrane is suitable for use as a DPM to suppress residual moisture in concrete and sand/cement screeds where the moisture levels are 98% RH or less, when tested with a properly calibrated surface hygrometer in accordance with BS 8203. As a two-coat application it may be used on subfloors where there is an absence of a constructional base DPM, provided there is no hydrostatic pressure. In some circumstances it may be used over cementitious screeds incorporating warm water underfloor heating systems. Ultra Floor DPM IT is also ideal for use as a primer/screed bonding agent for installations of polymer modified and proprietary cementitious screeds. NOTE: Ultra Floor DPM IT should not be used in projects where hydrostatic pressure is a concern. In such cases the use of pressure relief drainage and/or external tanking systems must be the primary method of protection against moisture. Subfloor Preparation: All substrates must be prepared to leave a sound, clean and surface dry subfloor. Oils, grease and other contaminants that may hinder adhesion must be removed. This includes release agents used in concrete curing processes as well as laitance, contamination and any weak surface materials. Joints in Subfloors: The nature of joints in the subfloor must be ascertained. If joints are designed to allow movement at perimeters, between bays of subfloor or between differently heated underfloor heating zones they must not be overcoated with Ultra Floor DPM IT. If joints are considered stable they may be infilled with Ultra Floor DPM IT bulked out with clean sharp sand to a slump resistant viscosity. Similarly hairline cracks and hollows may be infilled in the same manner. Mixing and Application: Air temperature should be a minimum of 10°C throughout application and curing. Floor temperature should be a minimum of 3°C above the dew point to ensure there is no moisture present at the subfloor surface which will hinder adhesion. Dew point is linked to atmospheric humidity and temperature. Most modern electronic moisture testing kits provide this function. The product should be stored at temperatures between 10°C and 25°C overnight, prior to use. This ensures that the product will be at a suitable viscosity for mixing and will have optimum pot life. 1. Take the larger tin (Part A) off of the smaller tin (Part B) but ensure you do not take the latch off the smaller tin until you have removed the larger tin. Please note if you do take the latch off before separating the components, Part B lid will come off. 2. Pour the hardener in the smaller component (Hardener) into the larger component (Resin). 3. At a slow speed, mix the parts using a power whisk for 3-5 minutes until a uniform consistent colour is attained. If required use a flat implement to scrape materials from the side to ensure they are fully mixed. DPM IT has a working time of up to 60 minutes but for best flow characteristics it is recommended to apply as soon as mixing has been completed. Apply Ultra Floor DPM IT to the substrate by pouring it onto the floor area to be treated. Always begin at the far point of the floor to ensure you do not need to walk over it after application. For use as a DPM the product should be spread using a suitable notched trowel to determine the correct coverage rate. Over roll the serrations using a short pile roller pre-wetted in Ultra Floor DPM IT to ensure a uniform coating is achieved. This should be done immediately following trowelling. It is recommended that Ultra Floor DPM IT is carried up the perimeter walls to the level of the damp proof course (DPC) provided that the substrate is stable to moisture. This can be done by brush or small roller to give an overall coating. Priming or broadcasting with sand will be required before further flooring materials are applied. When using as an adhesion aid/primer in industrial applications the product may be applied by roller. Allow Ultra Floor DPM IT to tack off before installing the screed. This will enable thinner sections of screed than normal as well as giving the added benefits of a bonded screed system.
