Why Choose ProtectGuard® MG?

Why Choose
ProtectGuard® MG?

ProtectGuard® MG Granite and Marble Sealer


ProtectGuard MG is a ‘new generation’ stone sealer designed to protect substrates with very low porosity. It strongly repels water, oil, grease, weak acids (fruit juice, tomato sauce etc), and other general stains. In terms of stain resistance it sits right at the top of the ProtectGuard range. It outperforms most competitors’ products. Independent testing puts it well ahead of the likes of Dry Treat and Lithofin.  When only the best will do, choose ProtectGuard MG!

ProtectGuard MG is highly water repellent. So it keeps substrates dry. This, in turn, prevents the growth of moss, mould and lichens.

ProtectGuard MG is ideal for protecting all dense low porosity materials. Such as:

  • Marble
  • Granite
  • Ceramics
  • Polished and crystallised surfaces
  • Stoneware
  • Porcelain
  • Low porosity silica – limestone materials
  • All smooth mineral substrates
  • Densified and polished concrete

ProtectGuard Marble and Granite sealer contains 90% active components, so you aren’t just paying for solvents. As a result it goes a long way. On dense surfaces coverage rates of up to 20m2 per litre are typical. It also comes with a 10 year performance guarantee. ProtectGuard MG provides outstanding value for money.

Advanced Invisible Surface Protection


  • High-performance protection against water, oil and stains
  • Abrasion resistant
  • Does not form a film, lets the material breathe
  • Invisible: does not change colour
  • UV and frost resistant
  • Slows down ageing and makes maintenance easier

High Performance Marble Sealer


Penetrating very dense and crystallised materials is not easy. This makes them very difficult to seal properly. Marble, in particular, has a crystalline structure that is notorious for making good sealers look bad. So marble is a good testing material for high end sealers. If it performs well on marble it will work as well, if not better on everything else.

ProtectGuard MG has been designed specifically for marble and granite. That’s what the MG stands for, Marble & Granite. As such, it makes an excellent marble sealer. No matter whether the stone is honed, polished, or even crystallised. ProtectGuard MG will penetrate into the surface to provide long lasting protection.

A Breathable Sealer


ProtectGuard MG is suitable for both indoor and outdoor applications. Use for walls or flooring. It is a impregnating type sealer which does not create a surface film. Materials remain permeable to air and water vapour. This allows the surfaces to breathe. Surfaces stay clean and healthy. Moisture in the substrate can escape as water vapour without any negative impacts on the sealer. This is especially important where rising damp is an issue. Film forming sealers cannot breathe and will delaminate, blister and peel under such conditions.

ProtectGuard MG Granite and marble sealer is colourless. It generally does not change the look or texture of the treated material. However, on certain materials it can have a very slight darkening effect. Doing a small test is always recommended before doing a full application.

It has a high level of abrasion resistance, so its fine to use on floors. It is UV and frost resistant and does not discolour with age. Since it doesn’t produce a film on the surface it won’t alter the natural slip levels of the surface.

Need Something Different?


There is a Protect Guard Sealer for All Types of Applications.

ProtectGuard MG is a solvent based sealer designed for dense and low porosity materials. It can be used on more porous materials, but this may become cost prohibitive. ProtectGuard MG needs to be applied to the point of saturation so the more porous the material is the more sealer you need to use. Therefore, there may be products that are more suitable.

There is a Guard Industry ProtectGuard Sealer to suit every application. For very porous materials consider using ProtectGuard®. For high traffic porous floors try ProtectGuard® HD. For colour enhancement consider ProtectGuard® WF Premium wet look sealer. If you need acid resistance ProtectGuard® Plant Based may the product for you.

Not sure how porous your surface is? Do a water droplet test. Put a drop of water on the surface you want to seal. Then time how long it takes for the droplet to soak in. Check the time against our sealer selection chart.

    • Apply the product in one go. Let it soak in and let the product dry (10 to 60 minutes depending on the porosity and temperature of the material).
    • Do not overload the material, remove any excess with a soft cloth dabbing the material before drying the product.
    • The surface dries in 1 hour.
    • The surface must be protected from traffic and liquids (rain, grease, etc.) for 24 hours
    • On very-low porosity or polished materials, the surface must be polished with a microfibre cloth after application.
    • Optimum efficiency of the product is obtained after 48 hours drying.

Uses


    • Slightly and very low porosity materials: marble, granite, sandstone, slate, polished materials, concrete, etc.
    • Floors and facades
    • New or old
    • Internal and external
    • Recommended for patios, pedestrian areas, living rooms, facades, stairs, etc.

Indicative Coverage

Frequently
Asked Questions

Very dense stone including marble, granite, travertine, porcelain tiles and polished concrete. It is a fluoropolymer sealer with a completely natural look, repelling water, oils and stains with a 10-year performance life.

Yes. It can be applied to vertical surfaces, but dwell time is shorter as excess will run. Apply in light coats and buff off excess with a microfibre cloth for best results.

Coverage depends on porosity:

  • ~12m²/L for marble, travertine, and bluestone
  • ~15m²/L for granite and imported sandstone
  • ~17m²/L for quartzite and slate
  • Up to ~20m²/L for dense or polished surfaces

Because marble is so dense, you get excellent coverage of up to 40m2 per litre in some cases - making ProtectGuard® MG very cost-effective for marble and granite despite the higher unit price.

One coat to saturation is typically all that’s needed. If performance reduces over time, additional coats can be applied later.

Yes. ProtectGuard® MG is the recommended variant for wet areas and bathrooms, providing excellent protection against water and staining in high-moisture environments.

Yes. It works well on concrete and maintains a natural look. However, acids can still etch the surface and may affect the sealer.

No. It does not alter the natural texture or grip of the surface when applied correctly.

ProtectGuard® MG is the product of choice for marble. Applied generously, it penetrates deep into the stone (10mm+) to prevent salt ingress and water damage. For a wet look finish, ProtectGuard® WF Premium is the option for colour enhancement.
