What does obliterating emulsion mean?

It means the paint is formulated to hide the surface beneath it. It does not guarantee complete coverage in a single coat.

Can I use Crown Trade Covermatt Obliterating Emulsion on new plaster?

Yes, it is intended for the first decoration of new interior plaster and dry-lined walls and ceilings. Surfaces must be sound, clean and suitably dry. Porous surfaces require a mist coat, as described in Preparation.

How much water should I add for a mist coat?

Add 40% clean water by volume: 400ml of water for every litre of paint. Where clean water is unavailable, Crown specifies one coat of Crown Trade Covermatt Drywall Primer instead.

Can I apply Covermatt over existing paint?

Crown recommends applying Covermatt over existing Covermatt only. For other existing paint finishes, choose a suitable alternative emulsion.

Is Covermatt washable or scrubbable?

No. If cleaning is necessary, wipe gently with a damp cloth and mild detergent. Rubbing or scrubbing can leave shiny patches or remove the coating. Choose a more durable finish for surfaces that need regular cleaning.

Is Covermatt suitable for kitchens and bathrooms?

For areas exposed to frequent splashes, grease, condensation or repeated cleaning, choose a finish specifically suited to those conditions.

How long does Covermatt take to dry?

At 20°C and 65% relative humidity, it is touch dry in 1-2 hours and ready for recoating after 4 hours. Allow longer in cooler or more humid conditions. Touch dry does not mean fully cured.

Does Covermatt need a more durable topcoat?

Covermatt is intended as an initial coating before subsequent decoration with a more durable paint. Choose the finishing paint according to the room's use and the level of cleaning required.
