This can be achieved through a variety of methods, including power washing, wire brushing, and the use of chemical cleaners.

Removal of Efflorescence and Contaminants

Efflorescence is the white, powdery substance that can appear on concrete and masonry surfaces as water-soluble salts leach out and crystallize. To remove efflorescence and other contaminants, you can use a masonry cleaner or a diluted solution of water and phosphoric acid. Apply the cleaner to the surface with a stiff brush, scrubbing thoroughly, and rinse with clean water. Be sure to wear the appropriate protective gear as you remove efflorescence, such as gloves and eyewear.

Leveling Uneven Surfaces

Uneven surfaces can cause problems when applying an acrylic render. To level an irregular surface, fill any holes or cracks with a patching compound or mortar mix. Once the patches have dried, use a straightedge or level to identify any high or low spots on the surface. Sand down high spots with a coarse-grit sanding block and fill low areas with additional patching compound. This step may require multiple rounds of patching and sanding to achieve a smooth, even surface.

Metal Surfaces

Metal surfaces can also be prepared for acrylic renders, so long as they are cleaned and treated properly. Key steps when working with metal substrates include the removal of rust and corrosion, as well as the application of primers and coatings to create a suitable surface for the render.

Rust and Corrosion Removal

Inspect metal surfaces for signs of rust or corrosion. Remove any visible rust or corrosion using a wire brush, sandpaper, or an angle grinder with a wire brush attachment. If a significant amount of rust is present, consider using a rust converter which can chemically convert rust into a stable and paintable surface.

Priming and Coating

After a metal substrate has been cleaned of rust and corrosion, the surface must be primed and coated to ensure a proper bond with the acrylic render.
