ResDev Pumadur PAS Clear is suitable for use over ResDev PumaDur PAS Coloured to seal decorative flake systems. Also suitable as a seal coat on highly decorative flooring systems, including ResDev Pumadur HPQ.

Application

Preparation

The surface to be coated must be clean, dry and free from oil, grease, dust and loose material or any other contamination that may impair adhesion or wetting out. High or low spots should be removed or repaired before proceeding. Remove excess flakes or aggregates from the surface by sweeping followed by vacuum. The use of light sanding is recommended for flakes to remove flakes standing proud.

When applied to a smooth resin finish, it is possible that Pumadur PAS Clear may fish-eye due to surface tension. Lightly abrading the surface followed by solvent wiping may cure this problem. If in doubt, apply a trial area of the system before specifying.

IMPORTANT: Humidity in the atmosphere is required for the successful cure of polyaspartic based coatings. As a result, polyaspartic coatings will take a significant amount of time to through cure if applied in excess of the recommended film thickness (250 microns). It is especially important to ensure that the substrate is flat and defect free so that material does not pool in excess of the recommended film thickness.

Mixing
Materials should be conditioned at 15C to 25C for 24 hours prior to use. Pre-mix the resin component as there will be slight settlement in the bottom of the container. Add the hardener component to the resin component and mix using a low speed electric mixer (300 - 500 rpm) fitted with a suitably sized Jiffy-style paddle for at least 3 minutes until homogeneous. Keep the mixing head fully submerged to avoid air entrainment. Use a straight edged spatula to scrape the sides and bottom of the mixing vessel several times as unmixed material will result in uncured patches in the final finish. Do not add solvent/thinners to the product.

Pot Life
Mixed material must be used immediately. When mixed, a chemical chain reaction takes place which creates heat and further reduces pot life. High ambient temperatures and humidity will reduce pot life. Low temperatures and humidity increase curing time.

Application

Squeegee and back-roll to provide a uniform film of 200 to 250 microns and avoid pooling. Use a cross-rolling technique to ensure even coverage. If required, repeat the procedure for a second coat. Edges and difficult to reach areas may be applied thinly by brush. Plan the work area to maintain a wet edge and work within the working time of the material. Due to the rapid cure, roller sleeves should be changed regularly (at least every hour).
