ProtectGuard HD - Heavy Duty Sealer
ProtectGuard 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.
ProtectGuard 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.
ProtectGuard 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.
ProtectGuard HD heavy duty sealer is tried and proven. It has been competitively selected for projects all over the world. Some examples include Tiananmen Square and the Beijing National Stadium in China, the Louis Vuitton Foundation Building in Paris, and the pavement around Whitehall in London. Further, it has a 10 year, AXA insurance backed guarantee for use in high traffic flooring applications.

A Natural Look, Permanent Anti-Graffiti Coating
ProtectGuard HD even repels graffiti! It prevents paint and ink from getting into the pores of treated surfaces. These can then be easily removed with Guard Remover Graffiti 2030 without damaging the sealer. This eco graffiti remover can be used safely with both ProtectGuard and ProtectGuard 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 ProtectGuard, ProtectGuard HD or ProtectGuard MG is a safe and effective way to retain that beauty while also providing protection against nuisance graffiti.
Easy to Use
ProtectGuard 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! Don’t 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.
Is ProtectGuard HD Right for You?
ProtectGuard HD will provide excellent protection on medium to low porosity materials. It is suitable for use on a wide range of products and surfaces. Some suitable materials include:
- Concrete
- Terracotta
- Bluestone
- Travertine
- Granite
- Synthetic & Reconstituted Stone
- Non-crystallised marble
How Much ProtectGuard HD Do You Need?
You need to apply one coat to the point of saturation. 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.
ProtectGuard HD may not be suitable or cost effective for very porous materials or very low porosity materials. For very porous materials consider ProtectGuard. For very low porosity materials ProtectGuard MG may be required. If you are after a colour enhanced appearance (how your materials look when damp) then ProtectGuard WF Premium is the product for you!
FAQs
Yes. ProtectGuard HD helps reduce moisture-related issues and makes surfaces easier to clean. In shaded or damp areas prone to moss growth, it is recommended to first apply a 1:1 mix of Guard Anti-M24 and water before sealing. This treatment kills moss root systems and continues working within the stone to help keep moss away.
Yes. ProtectGuard HD is breathable, allowing moisture vapour to escape while still protecting the surface. This makes it ideal for heritage buildings and older stonework where rising moisture may be a concern.
Yes. ProtectGuard HD is an excellent natural-finish penetrating sealer for slate floors, providing protection against water, oil and stains. For best results, the slate must be raw and free from any existing topical sealers before application.
