An epoxy resin primer that allows smooth concrete to be painted without mechanical preparation. For priming power floated, very smooth or non-porous concrete floors which are prone to rejecting paint.
Note: While great care is taken with the colour samples shown, no guarantee can be given that they represent exactly the colours offered.
Watco Powerfloat Primer is a virtually solvent free, two part, water based, epoxy resin primer designed for application to smooth, non-porous surfaces which are prone to rejecting paint.
The traditional way of preparing a power floated or polished concrete floor is by means of mechanical preparation such as shot blasting. Shot blasting can be expensive and can texture the surface leaving 'tram line' marks. One coat of Watco Powerfloat Primer eliminates the need for this mechanical preparation, and so retains the attractive smooth power floated finish.
Powerfloat Primer (available in Grey or Clear) — Powerfloat Primer can be over coated with most Watco coatings within 12 hours (based on a temperature of 20°C). If the intention is to overcoat Powerfloat Primer with a solvent based floor coating, such as Watco Concrete Floor Paint; it should be left for 5 days to thoroughly cure. We always recommend using Powerfloat Primer in the standard grey finish when using a coloured floor coating, and the clear version of Powerfloat Primer Rapid when applying a clear floor sealer such as Watco Protecta-Coat. If more than 5 days elapse after using the primer before applying the top coat, it should be lightly abraded to provide a key.
Powerfloat Primer Rapid (available in Grey only) — is a fast drying formulation which allows the floor to be over coated with a water based coating within just 4-6 hours (based on a temperature of 20°C), which enables the area to be put back into use as quickly as possible. When using a non water based coating it's essential that Powerfloat Primer Rapid is allowed to thoroughly dry so that all the water contained in the primer has escaped. We therefore recommend leaving the primer for 8 hours before applying a non water based Watco coating, such as Watco Fastcoat (polyaspartic resin), or Watco Epoxicote High Build (100% solids epoxy), or 5 days for a solvent based coating, such as Watco Concrete Floor Paint. If more than 5 days elapse after using Powerfloat Primer Rapid before applying the top coat, the primer should be lightly abraded to provide a key.
Both Powerfloat Primer and Powerfloat Primer Rapid now carry CE mark EN1504-2 and have impressive test results for adhesion, abrasion and impact resistance as well as for flexibility. They are also breathable and have an A+ VOC emissions rating with a low level of VOC.
Bare concrete — if surface laitance is present remove using Watco Etch & Clean. Flush with clean water and allow the surface to dry. If residual damp remains this is acceptable as Powerfloat Primer and Powerfloat Primer Rapid are breathable.
New concrete — should be left for four weeks to dry in the summer and six in the winter. Should surface laitance be present, prepare the floor usingWatco Etch & Clean. Flush with clean water and allow the surface to dry.
Remove the two inner tins from the tall outer tin. Stir the contents of each tin thoroughly and pour all of the contents into the outer tin (scrape around the inside of the tins to remove any residue). Mix the components together thoroughly using a spatula or similar wide bladed tool (a piece of wooden batten is ideal). Continue mixing until an even colour and consistency are obtained. Do not mix more than one pack at a time. If a paint stirrer fitted to an electric drill is used, also use the spatula to blend in any unmixed material from the sides and bottom of the tin.
Best results are obtained in warm (minimum 15°C), dry conditions with good ventilation. Apply with a medium pile roller, working well into the surface of the concrete. Do not exceed the maximum coverage of 30m per 5 litre pack, per coat.
