Smartkote Protectakote WB Smooth is a water-based, smooth polyurethane coating. This water-based solvent-free formulation is weather resistant, has a low odour, and is non-flammable for both interior and exterior applications. It’s enhanced with polyurethane for ultimate toughness, with excellent resistance to abrasion, chemicals and solvents. The single pack is ready to use, easy to apply and fast drying. A textured, anti-slip version is also available.

Product Uses

• Smartkote Protectakote WB Smooth is suitable for interior and exterior use.

• The smooth finish is ideal as a protective coating and can also be used to refurbish textured areas without adding more profile.

Surface Preparation & Priming

Ensure all substrates are thoroughly dry, clean, sound and free from any contaminants such as dirt, rust, salt, algae and grease. Protectakote WB 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. Old and new cement or concrete surfaces must be acid-etched, rinsed well and dried. Prime with an epoxy primer as per instructions if damp or oil contaminated.
• Wood: Abrade with a scouring pad or medium grit sandpaper and clean the surface. Wood must be dry or sealed before applying Protectakote WB Smooth directly.
• Fibre-glass: Lightly abrade and clean surface thoroughly with water. Allow to dry, then apply Protectakote WB Smooth direct.
• PVC: Abrade and clean well with water. Allow to dry before applying Protectakote WB Smooth direct.
• Gloss Paints and Varnish: Abrade with a scouring pad or medium grit sandpaper to remove all gloss. Clean away sanding dust and allow to dry thoroughly. Apply Protectakote WB 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. Clean away sanding dust and allow to dry thoroughly. Apply Protectakote WB Smooth directly.

Application

• Ensure substrates have been prepared.
• Ensure areas not to be coated have been masked off.
• Stir well before use using a flat paddle.
• Always apply a test patch of Protectakote WB 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 above steps.
• Protectakote WB Smooth should be applied in a number of thin coats. Although gas is not evolved during the curing process as with solvent-based Protectakote versions and pinholes will not occur, a number of thin coats will dry faster than a single thick coat.
• Brush-on: Protectakote WB Smooth should be “laid” onto the surface with a brush (do not brush backwards and forwards as with an enamel paint). Second or subsequent coats should be applied at right angles to the previous coat. Intercoat time is approximately 2 hours, when touch dry, depending on ambient conditions.
• Roller: Follow same instructions as per Brush-on. Intercoat time is approximately 2 hours, when touch dry, depending on ambient conditions.
• Curing time: Protectakote WB Smooth cures by evaporation. The coating will be touch dry in about 2 to 4 hours and allowing light traffic after 12 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.
• Overcoating and repair: Protectakote WB 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 WB Smooth is left for more than 24 hours after coating, it should be abraded before recoating to aid intercoat adhesion. If correctly done, Protectakote WB Smooth provides a seamless repair.

Cork Floors

• Presealed: Directly apply a single coat of Protectakote WB Smooth in a cross-hatch method, taking care to not miss any areas. Inspect while wet to ensure that all areas have been coated.
• Unsealed: Directly apply two coats of Protectakote WB Smooth at right angles to one another. The second coat may be applied after 2-3 hours or as soon as touch-dry, but within 24 hours.

Coverage

• 4m² per litre per coat. Applied in a 2 coat application. Giving an overall coverage of 2m² per litre.
• Three coats are recommended for high wear areas.
• Coverage will vary depending on the porosity and profile of the surface.

Cleaning

• Uncured Protectakote WB Smooth: Can be cleaned in its uncured state using water.
• Cured Protectakote WB Smooth: Can be removed with MEK (Methyl Ethyl Ketone) or by mechanical means.
• Remove any spills immediately as Protectakote WB is very difficult to remove once cured.
• Use hot soapy water to clean the coating.

Important

• Please read all instructions carefully before starting the project.
• Proper surface preparation is critical for successful application of Protectakote WB Smooth.
• Do not thin with any solvent. Water is recommended as an appropriate thinning agent.
• Do not apply to bare metal without an appropriate primer.
• All RAL colours shown for this product are approximations ONLY.
• Other colours available to order subject to a minimum order of 200 litres - extended lead times apply.
