The surface needs to be dry and clean free from dirt, dust, oils, algae and any other organic growth. Algae should be removed using Seal-er Algae Remover. All previous coatings/sealers need to be removed prior to application. Ensure any residue from cleaning/removal products are fully washed away. Test a small hidden area of the surface before use thus ensuring final results are as required.

  • Product supplied ready to use and should not be diluted. Shake well before use.
  • Ensure surface is thoroughly dry before application, if the surface is not fully dry whitening may occur. Never pour directly on to surface.
  • Apply with a long pile roller, brush or garden sprayer using fan attachment. Always apply a generous even coat avoiding any runs or drips, if any puddles occur mop up immediately with a cloth.
  • Apply once for a low sheen finish or apply two to three coats for a higher sheen finish.
  • DO NOT allow the product to cure in between applications.
  • Where the surface is more porous apply a second coat no more than two hours after the first.
