Surfaces should be clean from dust, dirt, oils, grease, curing compounds, other coatings, efflorescence and laitance before applying PCA SurfaceShield® Pro – ‘Natural Look’. If strong acidic or caustic cleaners are used, neutralise the surface with a diluted solution of PCA Stone Degreaser™, thoroughly and completely wash/rinse to remove any residues.


  1. Ensure the surface is clean and dry.
  2. Any existing stains must be removed prior to sealant application.
  3. Cover surfaces not intended to be treated.
  4. Apply an even first coat using a solvent resistant low-pressure sprayer or a lambswool applicator.
  5. Allow sealer to penetrate the surface for 10-15 minutes and thoroughly wipe all excess sealer with clean and absorbent towels.
  6. The second coat should be applied evenly 30-40 minutes after first coat as directed in steps 4-5
  7. After final application, thoroughly wipe all excess sealer with clean and absorbent towels.
  8. A full cure is achieved in 24 – 72 hours. Foot traffic can resume in 8 hours, driving in 24 hours.
