Beautiful stylish results are important when coating furniture. The Sayerlack Hydroplus water-based range can be used to produce finishes that are indistinguishable in quality, strength and chemical resistance as two-pack polyurethane finishes. Sayerlack is at the forefront of waterbased technology that is conscientious about the wellbeing of people and the environment. AU0474 is a premium two-pack, waterbased, pigmented primer designed for minimal grain raising on interior joinery onto MDF and Masonite substrates such as Flat Surfaces, Frames, Baseboards and Doors . It is available in White and Black for spraying under darker colours and can also be used as a single pack product.

As a 1K product, it has high pigment and solids content, excellent filling properties, ensures a consistent colour even at high film thicknesses. If it is catalysed with 2% of AH1550/00 it will give the primer good elasticity and an even higher covering power. It is the ideal product for all MDF and Masonite substrates with a flat geometry such as Doors, Baseboards and Frames. Spray using a conventional gun, airmix system or airless system. It is fast drying and a smooth finish achieved in two coats and if a higher build is required, a third coat can be applied. It comes ready to use and can be catalysed with 2% of AH1550/00 and thinned using water if necessary.

For best results, we suggest preparing the surface using 240-320 grit stearate abrasives as they provide a higher efficiency than conventional. Ensure the surface is completely clean of dust and debris before coating.


With good drying conditions and air circulation (20°C), a good build on closed pore or semi-closed pore can be achieved with two coats of 80-140 g/m² with an interval of 2 hours in between, in good drying conditions and with air circulation (at 20°C and with 65% of relative humidity). Under these circumstances, the substrate can be sanded after 3-4 hours. Lower temperatures and higher relative humidity can lead to longer drying times, but it is possible to speed up drying using heated ovens. When a higher build is required, a third coat can be applied, but the waiting time is extended to at least 4 hours and sanding can take place after 6-8 hours.


Sayerlack AU0474/** Primer can be over coated with any pigmented Waterbased Topcoats such as Sayerlack AT99**/XX.
