ProtectGuard Stone Sealer - Natural look sealer

ProtectGuard – Natural Look Sealer

ProtectGuard is a natural look sealer that delivers outstanding protection to all types of porous materials. It is an eco, water based stone sealer that repels water, oils, stains and even graffiti. It comes with a 10 year guarantee and has been proven effective for over 20 years in some cases. It is currently protecting iconic structures all over the world. Such as Bernini’s Columns at St Peters Square at the Vatican, and the Louvre in Paris. ProtectGuard, by Guard Industry, is the stone protection product of choice.

ProtectGuard helps tackle the deterioration caused by smog, greasy stains, and penetration of liquids.  Treated surfaces will benefit from an increased life-span and will be easier to clean.  Due to it’s high water repellency and vapour breathability, it keeps porous materials dry. This stops mould and mildew growth. And will be difficult for lichens and moss to become established. Your materials will stay healthy and clean.

ProtectGuard works by stopping stains from soaking into the substrate. It repels all kinds of liquids keeping them above the surface. They can then be easily cleaned off. Surfaces are much easier to keep clean when they are protected with this stone sealer. It even stops chewing gum from sticking to the surface, and allows for easy, residue free removal. 

ProtectGuard is also an anti graffiti coating! It stops paint and ink from soaking into the pores of the material. It can then easily be removed from the surface with GraffiGuard 2030 Eco. Guard Industry have developed this safe eco cleaner specifically for use with ProtectGuard. It will safely remove the graffiti without damaging the ProtectGuard. The seal remains intact for ongoing protection. This is a very safe and effective means of controlling and managing graffiti. No other natural look sealer that can do that! Except perhaps, ProtectGuard HD


ProtectGuard is suitable for indoor and outdoor use. It is designed for use on all types of porous building materials. Use with confidence on:

  • concrete.
  • cement.
  • plasters.
  • natural and synthetic stone.
  • terracotta.
  • paving and more…

ProtectGuard lets Materials Breathe

ProtectGuard Breathable SealerProtectGuard does not product a surface film. This full penetrating sealer leaves the treated surface permeable to air and water vapour. This enables any moisture trapped in the material to escape. This is important for most outdoor sealing applications. Water always seems to get in somehow! There are a few applications where moisture issues are very common. These include:

  • retaining walls.
  • low or below grade floors.
  • water features.
  • paving around pools.

ProtectGuard is completely invisible after application. So it does not change the look or the texture of the treated surface. It is UV and frost resistant and does not change colour with age. Its also non slip! Since it does not produce a surface film it will not alter the natural grip levels of the material. As such, full penetrating sealers should always be used in areas where slips need to be minimised.

Q & A

how do I calculate/estimate how much an area of concrete pavers a 5l container of protect guard will cover ? manuela witte asked on April 19, 2024

Typical usage rates on concrete pavers is 4m2/L. So a 5L container will be enough for roughly 20m2
