ProtectGuardยฎ HD โ Heavy Duty Sealer
ProtectGuardยฎย HD heavy duty natural look sealer is the product of choice for all those heavy duty sealing applications where you want to preserve the natural beauty of your materials. It has all the water-repellent, oil-repellent and anti-soiling properties of ProtectGuard but has been specifically designed to have a very high abrasion resistance. This makes it able to withstand high traffic and high soiling loads. As such it is perfect for floors with lots of pedestrian traffic, like footpaths, malls and entertaining areas. It is also suitable for factory floors, parking areas and driveways.
ProtectGuardยฎย HD is a natural look sealer that will not alter the natural look or texture of the materials being sealed. This also means that it will not alter the natural grip of the flooring materials. This is particularly important in pedestrian applications where slip hazards need to be eliminated. This fact, coupled with its durability make it an excellent choice for sealing paving around swimming pools.

ProtectGuardยฎย HD acts against the main causes of degradation, such as atmospheric pollution, greasy soiling, water seepage, acid rain, chewing gum and general dirt and grime. It prevents these contaminants from soaking into the surface and therefore prevents permanent staining. Spills and stains can then easily be cleaned off the surface during regular maintenance cleaning.
ProtectGuardยฎ HD heavy duty sealer is tried and proven.ย It has been competitively selected for projects all over the world. Some examples include Tian An Men Squareย and theย Beijing National Stadiumย in China, theย Louis Vuitton Foundationย Building in Paris, and the pavement aroundย Whitehallย in London. Further, it has a 10 year, AXA insurance backed guarantee for use in high traffic flooring applications.

ProtectGuardยฎ HD is a Natural Look, Permanent Anti-Graffiti Coating
ProtectGuardยฎ HD even repels graffiti! It prevents paint and ink from getting into the pores of treated surfaces. These can then be easily removed with GraffiGuard 2030 Eco without damaging the sealer. This eco graffiti remover can be used safely with both ProtectGuardยฎ and ProtectGuardยฎ HD. This is a very safe and effective means of controlling and managing graffiti.
Most anti graffiti coatings will change the appearance of the surface. Such coatings detract from the raw beauty of natural materials. Using ProtectGuardยฎ, ProtectGuardยฎ HD or ProtectGuardยฎย MG is a safe and effective way to retain that beauty while also providing protection against nuisance graffiti.
ProtectGuardยฎ HD is Easy to Use
ProtectGuardยฎ HD is a safe water based product. It is applied in an easy one coat application with either a low pressure garden sprayer, roller or a brush. We recommend using a garden sprayer with a nice even mist like spray.
Apply one coat to the point of saturation. Then walk away! Donโt over apply. You just need enough product to achieve a wet film that persists for a minute or so. Protect the surface for 24 hours. Best performance achieved after 7 days. Clean-up any equipment with water and reuse on your next job.

How Much ProtectGuardยฎ HD Do You Need?
You need to apply one coat to the point of satuaration. Therefore, how much sealer you need will vary depending on the porosity of the materials to which it is applied. Application rates in the table below are only to be used as a rough guide:
| Concrete | 5 m2/L |
| Reconstituted Stone | 6 m2/L |
| Terracotta | 7 m2/L |
| Non Crystallised Marble | 10 m2/L |
| Granite | 12 m2/L |
We always recommend performing a water droplet test on your materials to help with material selection. The test is easy to do. Simply put a drop of water on the material and see how long it takes to soak into the surface. Then compare to the chart to see which products are suitable.
ProtectGuardยฎ HD may not be suitable or cost effective for very porous materials or very low porosity materials. For very porous materials consider ProtectGuardยฎ. For very low porosity materials ProtectGuardยฎ MG may be required. If you are after a colour enhanced appearance (how your materials look when damp) then ProtectGuardยฎ WF Premium is the product for you!
