Rustin's MDF Sealer

The simple answer to getting a good finish on porous boards and at the same time stop the 'blotting paper' effect. This water/acrylic emulsion produces a clear sealer coat on porous board surfaces such as MDF and hardboard to reduce the uptake and improves the economy and finish of varnish and paint applications to these materials. Apply this as a sealer coat in addition to the paint system and not as a substitute for any of the coats recommended by the paint manufacturer. Quick drying, low odour and easy to clean up.
