Features & Benefits

  • Solvent-based
  • For use on block paved drives and pathways, natural stone patio areas and cement based flagstones
  • Repels water, dirt and oils
  • Used as a sealer and joint stabiliser
  • Long lasting acrylic-based formula
  • Single-pack product
  • Can be brush, roller or spray applied
  • Do not use if surface is damp or rain imminent
  • Do not use on non porous or previously treated surfaces (unless sufficiently weathered to allow penetration)

Spreading Rate

These will vary depending on substrate, the site conditions and longevity required.

Typically spreading rates will vary depending on the end use.

  • Coverage is approximately 5 – 7 square metres per litre per coat but will vary depending upon application method, surface porosity and ambient conditions

Drying Times

  • Surface dry in 1-2 hours. Re-coatable overnight


  • Surfaces should be clean, dry and free from oil, grease, dust, laitance and any other deleterious materials
  • Ensure the paving surfaces to be treated are clean and free from any mould or fungal growth
  • If oil stains are present, remove with detergent and hot water
  • Ensure cement composite pavers are thoroughly degreased and free from release agents which will affect penetration
  • If mould and fungal growth are present, clean surfaces with Britannia Fungicidal Wash as directed
  • All artificial stone (cement based) and all block pavers must be left for three months minimum after placing before over coating with this product
  • This will allow salts to leach out which otherwise may cause unsightly white patches appearing beneath the sealer, especially when the patio is wet


  • Stir well before use
  • Use as supplied without thinning down
  • Do not apply in temperatures below 5°C or above 25°C and should not be subjected to extremes of temperature until completely dry
  • Please follow the coverage rates shown in Spreading Rate Section
  • The surface should be sectioned off to assist accurate coverage. Apply thin uniform coats maintaining a wet edge but do not allow to puddle
  • It is important to undertake a representative test area to ensure that the product is suitable for your requirements prior to commencement of the project and assessed for final appearance, chemical resistance and wet & dry slip resistance. This is particularly important where the surface has previously been sealed
  • Application should ideally be by an airless sprayer designed for solvent based products but application by brush or roller is also suitable
  • During application care should be taken to protect adjacent areas and equipment from overspray
  • Under normal conditions it will be touch dry within 1 - 2 hours and may be lightly trafficked in 24 hours


  • Fungicidal Wash should be used every 6 to 12 months to control the surface of fungal and algal growth
  • Maintenance coats can be applied when signs of wear appear. Thoroughly clean and dry surface before application


  • All equipment should be cleaned using Special Solvent (Not White Spirit), xylene, or similar
  • Flush sprayers thoroughly
  • Always clean equipment in a well ventilated area
