Ensure that surfaces are sound and free from dust, oil, grease, dirt, and debris. Surfaces must be thoroughly dry – no more than 12% moisture content.

• Remove all loose and friable plaster, old paint and wallpaper by most suitable means.
• Narrow cracks are best widened into a “V” shape with a sharp tool to ensure effective filling.
• Touch in nails and screw heads with an appropriate primer.
•  Cracks or holes deeper than 5mm must be filled with the appropriate Mauvilac Multipurpose Crack filler Ready Mixed.
• Powdery plaster should be primed with Mauvilith Sealer to aid adhesion.
• Previously painted surfaces must be sanded to a flat finish before application of Mauvilac Pre-Paint SmoothOver.

Apply Mauvilac Pre-Paint SmoothOver with a wet plastering trowel, skimming tool or large scraper, moving in an upward curve, maintaining a firm and even pressure.

Apply only as much Mauvilac Pre-Paint SmoothOver as needed. It is advisable to build the film thickness in multiple layers rather than one thick coat (minimum thickness 2mm with a maximum thickness not exceeding 5mm). Don’t worry about small irregularities or ‘tramlines’.
Allow the final layer to dry for at least 2 hours before sanding with 100 grit sand paper to a smooth finish. Thick applications or damp weather may require a slightly longer drying period.

As an alternative to sanding, Mauvilac Pre-Paint SmoothOver can be floated or polished. As soon as Mauvilac Pre-Paint SmoothOver is touch dry (not fully dry), use a wetted foam trowel to polish the surface in a circular movement, cleaning and wetting the trowel between strokes to achieve the ultimate Mauvilac Pre-Paint SmoothOver finish.

Mauvilac Pre-Paint SmoothOver should be used from corner to corner to ensure plaster profile consistency. If used to patch poor plaster work, a difference in finish will be visually evident once over-coated in different lighting conditions, etc.
