ResDev Pumadur PAS Coloured provides a UV-resistant, tough, hard wearing coating system and can be used to produce decorative flake systems in conjunction with ResDev Pumadur PAS Clear.
This product is an ideal floor paint for decorative applications, warehouses, laboratories and food preparation areas.
Preparation
Concrete substrates must have a minimum compressive strength of 25 N/mm2 and a minimum pull-off strength of 1.5 N/mm2. Substrates must be dry, clean and free of surface laitance and contaminants such as dirt, oil, grease, poorly bonded coatings and surface treatments. If in doubt, apply a test area first. Inadequate preparation will lead to loss of adhesion and failure. In coatings, there is a tendency for the finish to mirror imperfections in the substrate. Grinding, or light vacuum-contained shot-blasting, is therefore preferred over planing for these systems. High or low spots should be removed or repaired before proceeding. Concrete must include a functional damp-proof membrane. Concrete substrates must have a moisture content ≤ 4% by weight (< 75% RH) otherwise ResDev Pumaprime DPM must be used as a primer.
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 15°C to 25°C 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
Spread to the desired thickness with a rubber squeegee and finish immediately with a roller. Avoid pooling. If, when cured, there are dry/patchy areas, 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).
If required, broadcast decorative flakes or coloured quartz aggregate into the binder to saturation so that aggregates fall vertically into the binder. Fully broadcast systems may take longer to cure than the coating alone. Ensure sufficient cure has taken place to resist foot traffic without damage before applying subsequent coats.
Remove excess flakes/aggregates from the surface by sweeping followed by vacuuming until the surface is free from all loose particles. Seal using ResDev Pumadur PAS Clear.
Components: | Two Pack |
Type: | Solvent free polyaspartic |
Finish: | Gloss |
Stock Colours: | Black, White, Red, Light Grey, Mid Grey, Safety Yellow & Green. |
Tintable: | No |
VOC Content: | 0.0g per Litre |
Volume Solids: | 100% |
Suitable Substrates: | Concrete |
Application Method: | Rubber Squeegee, Roller |
Theoretical Coverage: | The coverage rate will vary depending on the texture and porosity of the substrate, film thickness and application technique. Two coats may be required to avoid missed spots. The mixed density of the material is approximately 1350 kg/m3. As a guide, an application rate of 3 to 5 m2/kg will produce a film thickness of 250 to 150 microns respectively on smooth, non-porous surfaces. Do not apply at thicknesses greater than 250 microns as these films will take a significant amount of time to through cure. |
