Technical Finishes Smooth ’n Patch
Smooth ’n Patch is a decorative, pigmented cement-based top layer that has to be mixed before application. It is self-levelling and can be applied over concrete or tiles, as was done in Fix it with Flair 2015 runners-up Anton and Julie Oosthuizen’s house in Greyton.
Installation As with any cement floor, the surface should be primed with Smooth ’n Patch Liquid or Seal & Strengthen. If you’re installing Smooth ’n Patch over tiles, prepare the surface with Technical Finishes Probond, says Chanté Mynhardt, sales and marketing assistant at Technical Finishes. “Smooth ’n Patch can be installed over any tiles, as long as they aren’t cracked or damaged. They should be grinded first to get rid of the glaze and to ensure that the primer can be absorbed into the tile.”
Once primed, apply the Smooth ’n Patch in a layer that’s 3–4mm thick. It dries fairly quickly (about 30–40 minutes, depending on the size of the surface) after which the Smooth ’n Patch mixture has to be gently hand-floated to ensure a smooth surface. Once this is done, allow the surface to set overnight – curing takes at least 24 hours. The floor must then be sealed with any of a variety of sealants, depending on your preference for either a high-gloss or matte finish. It’s advisable to apply 2–3 coats of sealant.
Cost Between R300 and R600/m², including installation; prices vary depending on the thickness of the application.
It's a DIY job! Using an approved applicator is highly recommended but Anton and Julie did it themselves.
