Acid free and bleach free, GK Pro is a Quarternary Ammonium Biocide for cleaning and sanitising external hard surfaces. It is non-invasive and the least aggressive way of treating as it does not require any form of jet washing or abrasion.

In avoiding the use of high-pressure jet washing and aggressive cleaning techniques, GK Pro does not cause any damage to old/weathered surfaces. If used correctly, it is guaranteed not to adversely affect any product, coating, fixing, sealant or jointing used in construction.

It is suitable for cleaning walls, render, stone, timber, industrial cladding, polycarbonates, polytunnels, roof tiles, slates & thatch, tarmac & driveways, artificial sports surfaces, children’s play park equipment, wet pour and other rubber bonded surfaces.

How to use:

  • Apply on a dry, wind-free day using a low-pressure sprayer.
  • Avoid overspray or excessive run-off onto lawns as this may cause scorching (we recommend fully drenching and covering neighbouring foliage with clean water before application.)
  • Do not use GK Pro as a moss treatment for lawns/flower beds or as an algae treatment for pond water.
  • GK Pro is safe for children and pets once it is dried but keep them away during application and while still wet.
