- Field of Application
Polem A SD is designed to be used as a solid, elastic substrate and porefiller prior to the application of flexible flooring Systems. Please refer to the individual system data sheets. A functioning primer must be installed prior on the substrate and known to be effective.

- Substrate Preparation
All substrates must be structurally sound, clean and dry and free from oil, grease and loose material and any other contamination which might impair adhesion. Mechanical preparation such as captive shot blasting, scarification, and diamond grinding for edge work should be used to produce a substrate surface profile suitable for the application of a resin finish. The tensile strength of the substrate should exceed 1.5MPa. The residual moisture content should be less than 4%. Polem A SD should be applied when substrate temperatures are constant or falling to minimize the risk bubble and void formation due to expansion of air within the substrate when temperatures are rising. This is particularly important to note on external applications. The curing reactions are influenced by the ambient, material and substrate temperatures. Low temperatures lengthen the pot life, open- and curing times. High temperatures shorten pot life, openand curing times. The temperatures should not fall below the minimum stated until the material is fully cured. The temperature of the substrate must be at least 3°C above the dew point both during the application and for at least a further 24 hours (at 15°C).
- Application
Polem A SD is supplied in prepacked units. Before mixing, precondition both A and B components to a temperature of approximately 15 to 20°C. Pour the entire contents of part B into the container of part A. Mix with a low speed (ca.300 rpm) electric drill and paddle for at least 3 minutes until homogeneous. Scrape the sides and the bottom of the container several times during mixing to ensure complete mixing. Keep the mixing head submerged to avoid entrapping air. Do not work out of the original container. Decant the mixed material into a fresh container and remix for another minute. Polem A SD is applied by a 4 mm tooth squeegee and finished by spike roller. Protect the fresh layer from water and condensation which can cause a white bloom and tackiness which will be detrimental to subsequent layers.
