Smartkote Protectakote UVR Smooth

Smartkote Protectakote UVR Smooth is a tough, aliphatic polyurethane coating, which forms a colour-fast, abrasion and weather resistant film. Protectakote UVR Smooth is single component, ready to use and easy to apply. It can be used as a protective coating for many industrial and marine maintenance and new installations on exterior and interior surfaces.

• Lead and heavy metal free.

Product Uses

• Can be applied to: metal, concrete, wood, fiberglass, PVC, rubber and glazed tiles.
• Automotive parts requiring protection and abrasion resistance
• All indoor and outdoor flooring applications
• Demarcations on floors and steps
• Emergency exits and fire escapes
• Demarcations around machinery
• Bridges, steps, walkways, decks and helicopter pads on ships
• Industrial tanks, piping and machinery requiring outdoor protection

Coverage

3m² per litre per coat. Applied in a 2 coat application. Giving an overall coverage of 1.5 m² per litre.

Coverage will vary depending on the porosity and profile of the surface. Three coats are recommended for high wear areas.

Surface Preparation

Ensure all substrates are thoroughly dry, clean, sound and free from any contaminants such as dirt, rust, salt, algae and grease.

Protectakote UVR Smooth exhibits good adhesion to most primers. All non-porous substrates with the exception of painted surfaces require a primer. Substrates differ significantly, and so all new applications should be tested for adhesion first.

• Steel: Abrade surface lightly and remove any surface rust or mill scale by sanding, wire brushing, with a chipping hammer or sandblasting. Prime with Smartkote Protectakote 2K Metal Primer as per instructions, within 30 minutes.
• Galvanized Iron: Clean away grease and dirt with a suitable galvanized iron cleaner until a water break-free surface is attained. Rinse well with water and allow to dry. Abrade to provide a key and prime with Smartkote Protectakote 2K Metal Primer the same day as the surface was prepared to avoid re-contamination and flash rust.
• Aluminium: Abrade to fresh metal, clean well using detergent. Prime with Smartkote Protectakote 2K Metal Primer as per instructions within 30 minutes.
• Concrete: Allow new concrete at least 28 days to cure. Non-porous cement must be acid-etched, rinsed well and dried. Prime with Duram Duraprime as per instructions if weak, damp or oil contaminated.
• Wood: Abrade, clean and allow to completely dry before applying Protectakote UVR Smooth directly. Dilute the first coat with 10% Xylene to aid penetration.
• Fibreglass: Abrade well, solvent wipe with Xylene and apply Protectakote UVR Smooth directly onto the surface.
• PVC: Abrade and clean well using Xylene. Allow to dry before applying Protectakote UVR Smooth directly. An adhesion test is recommended prior to use.
• Rubber (nitrile or chloroprene): Clean well using detergent or cleaning solvent such as Xylene. Allow to dry. An adhesion test is recommended prior to use.
• Glazed tiles: Glazed tiles must be cleaned and treated with an organosilane primer eg. Smartkote Protectakote Clear Primer Treatment for adhesion of Protectakote UVR Smooth.
• Gloss Paints and Varnish: Abrade with a scouring pad or medium grit sandpaper to remove all gloss. Solvent wipe with Xylene, allow to dry and apply Protectakote UVR Smooth directly.
• Motor Vehicles and Painted Metal: Remove heavy dirt and rust. Previously painted surfaces need to be lightly abraded using a scouring pad or medium grit sandpaper to remove all gloss. Solvent wipe, allow to dry and apply Protectakote UVR Smooth directly.

Application

• Take care when opening as contents may be under pressure.
• Wear safety goggles and protective gloves.
• After substrates have been prepared, ensure they are completely dry, tests for adhesion have been completed and areas not to be coated have been masked off.
• Stir well before use using a flat paddle.
• Always apply a test patch of Protectakote UVR Smooth to ensure the substrate has been properly prepared and primed. Check adhesion of the coating by cutting a small X in the coating using a utility knife. Firmly apply a piece of packaging tape over the centre of the X cut, then pull off with a fast snap. The adhesion is suitable if no significant coating is removed beyond the X cut. If the coating fails this test, then additional surface preparation is required – repeat the surface preparation steps above.
• Brush/Roller: Protectakote UVR Smooth should be “laid” onto the surface with a brush/roller (do not brush backwards and forwards as with an enamel paint). Two coats will result in a final dry film thickness of 0,6mm to 0,8mm. Second or subsequent coats should be applied at right angles to the previous coat. Intercoat time is approximately 2 hours, or when touch dry, depending on ambient conditions.
• Spray: Dilute Protectakote UVR Smooth with 10% Xylene. Fill spray gun pot, and attach airline providing a minimum pressure of 5 bar. Protectakote UVR should be applied in thin coats to prevent “mudcracking” during drying. Depending on the application, two or more coats can be applied. Ensure each coat is dry before applying the next coat. Intercoat time is approximately 2 hours, or when touch dry, depending on ambient conditions.
• Curing time Protectakote UVR Smooth cures with atmospheric moisture. The coating will be touch dry in about 2 to 4 hours and allowing light traffic after 9 hours. Full strength and chemical resistance is achieved in 4 to 7 days, but normally the coating can be put to use after 24 hours.
• Accelerated cure: In areas of low atmospheric moisture, temperature or when shorter curing times are required, Smartkote Protectakote UVR Accelerator can be added.
• Overcoating and repair: Protectakote UVR Smooth can easily be repaired or overcoated. The old surface should be well cleaned and then abraded by wire brush or sandpaper, and damaged surfaces must be cut out to provide an area without loose edges. Follow application instructions. If Protectakote UVR Smooth is left for more than 24 hours after coating, it should be abraded before recoating to aid intercoat adhesion. If correctly applied, Protectakote UVR Smooth provides a seamless repair.
