How to Measure Size in m²

It is simple to calculate the square metre size of an area.

When measuring rectangular shaped areas. Just multiply the length by the width in metres and you have the answer.

When measuring more complex shapes it is best to divide them into separate rectangles and then add them together to get a total area.

Natural Stone Sealing

Deepshield™ long-life protection effectively repels dirt and contaminants from natural stone.

Natural stone offers benefits sure to please any home owner, highly durable, unique and with a timeless quality that never goes out of style. Natural stone adds value to your property and when looked after, not only lasts a lifetime, but will also require little maintenance.

If investing in natural stone or looking to protect a current installation, it is important to consider that all stone is to varying degrees porous, and will absorb liquids such as water, water-borne salts and oils rendering them prone to staining and deterioration. Being porous also means that stone naturally breathes, which allows vapour to escape and prevents harmful moisture from building up within the stone.

With proper care, natural stone will remain stain resistant for years. Deepshield™ innovative penetrating sealers form a protective barrier that effectively prevents staining agents from being absorbed into the stones pore structure without changing the stone's appearance or texture. Sealing with Deepshield™ is the first important step towards protecting your investment against chemical attack, deterioration and contamination.

Deepshield™ penetrating, breathable sealers prevent staining, and extend the life of natural stone by protecting from within the stones pore structure, and are appropriate for installations where concerns with efflorescence, mould growth and other moisture-related issues exist. Deepshield™ is resistant to UV (sunlight exposure), chlorine and weather effects and can be applied to interior and exterior natural stone flooring, tiling, kitchens, bathrooms, wall accents, showers, vanities, countertops and much more.

Deepshield™ sealers are relied upon by hundreds of stone professionals and thousands of DIY home owners. We are dedicated to ensuring the durability and preservation of natural stone from residential surfaces to large scale commercial applications.

Deepshield™ Transparent or Colour Enhancing Penetrating Sealer

Deepshield™ sealers can be used to achieve a different "look" for most porous surfaces. Deepshield™ Colour Enhancing Penetrating Sealer is formulated to slightly darken and highlight the character and texture of coloured interior and exterior natural stone and to rejuvenate and improve the appearance of worn or faded stone. Deepshield™ Colour Enhancer produces excellent results on slate tiles that have a natural chalky appearance, hiding the chalkiness and bringing out the colour of the stone.

Granite, Marble and Bluestone

Deepshield™ GOLD penetrates highly polished surfaces and dense materials such as granite, marble and bluestone against water and oil based stains as well as performs extremely well on most other tile and stone. Deepshield™ GOLD is based on the latest fluoro-bond technology and will repel dirt and contaminants from your surfaces for up to 15 years without altering the appearance or texture of your stone.

Sealing your natural stone with Deepshield™ will:

sealed marble floor
  • Reduce staining and grime build up
  • Ensure maintenance becomes much easier
  • Eliminate bacteria forming
  • Help prevent and reduce efflorescence build-up
  • Extend the life of your natural stone
  • Lower the risk of cracking and flaking grout
  • Keep surfaces non-slip

Deepshield™ contains tiny nano-particles designed to penetrate the micro-pore structure of stone. The sealer is absorbed deep inside the pores and once the carrier evaporates, the nano-particles remain, sealing the pores and keeping moisture and stain carrying substances out.

Deepshield™ water-based sealers prolong the life of your surfaces by taking full advantage of recent advancements in nano-technology and fluoro-bond technology. Deepshield™ forms a bond to your surfaces stronger than any mechanical or hydrogen bonding of conventional film forming sealers, providing unmatched long-term stain resistance and reliability.

Pre-Sealing Preparation

Any surface to be sealed should be clean and looking just as you want it prior to sealing - it may be very difficult to remove blemishes once sealed without once again having to remove the sealer. Acidic cleaners should not be used on sensitive natural stone as they will cause damage.

Frequently Asked Questions

What can happen if stone is not able to breathe?

Stone has an internal structure that is not totally solid. Moisture present in the ground can be wicked or drawn up into the stone by capillary action. If natural vapour transmission is not allowed to take place, moisture gets trapped and can cause chemical and physical changes within the stone. This action of decay in natural stone may take the form of pitting, spalling, flaking and oxidation.
Will Deepshield™ make my surfaces slippery?

Deepshield™ will not affect the slipperiness of your surfaces, and does not cause any yellowing or leave a visible shine. Deepshield™ is ideal for use around swimming pools and other wet areas.
What makes Deepshield™ GOLD different?

Deepshield™ GOLD is a deep impregnating (penetrating) sealer based on the latest fluoro-bond technology, specifically engineered for dense surfaces as well as most other natural and man made stone surfaces. Deepshield™ GOLD penetrates the pore structure rather than sit on the surface and once cured, will not alter the appearance of your tile or stone.
Deepshield™ GOLD will protect your stone from water and oil based stains for up to 15 years by chemically reacting with the surface pores, creating a long lasting, breathable protective barrier that also results in regular maintenance becoming much easier.
What is the difference between an impregnating sealer and a topical sealer?

Topical sealers produce a physical barrier over the surface which also creates a darkening, yellowing or glossy effect. Surface (topical) sealers usually don't last long, can make the floors slippery and need to be completely removed the next time sealing is required. Salts and efflorescence may also build-up under the non-breathable surface, causing the coating to appear cloudy.
Why seal stone?

Building materials such as natural stone, concrete, brick, tiles and grout are all made up of countless invisible capillary pores. This makes them porous and allows the absorption of damaging liquids such as water, water-borne salts and oils which cause natural stone to deteriorate prematurely and in doing so reduce its usefulness. Examples of deterioration include; weathering, loss of strength, efflorescence, salt attack, sulphate attack, unsightly staining, biological attack, reinforcement rusting, chemical attack, swelling, embrittlement and picture framing. Sealing can help eliminate or significantly reduce most of these problems from natural stone.
What is the difference between Deepshield™ GOLD and Deepshield™ Transparent Penetrating Sealer?

Highly polished surfaces and dense materials such as marble, granite and bluestone have extremely fine micro pores that require a specific formula to penetrate. Deepshield™ GOLD is based on the latest fluoro-bond technology and designed to penetrate and chemically bond to the micro pores of dense surfaces, protecting for up to 15 years. Both Deepshield™ GOLD and Deepshield™ Transparent Penetrating Sealer provide the highest level of protection against water and oil based stains without altering the surface texture or appearance.
What is the difference between Deepshield™ Transparent Penetrating Sealer and Deepshield™ Colour Enhancing Sealer?

Deepshield™ Transparent Penetrating Sealer enters the pore structure of your stone and once cured does not alter the appearance, whereas Deepshield™ Penetrating Colour Enhancing Sealer is designed to also slightly darken and enrich the natural beauty of stone and provide a “wet look” while not affecting the surfaces slip resistance properties. Deepshield™ Transparent Sealer and Deepshield™ Colour Enhancing Sealer protect against water and oil based stains for up to 10 years.
Can Deepshield™ GOLD be used on polished and less adsorbent stone surfaces?

Yes. Deepshield™ GOLD will not harm any stone, tile or grout surface and is specifically designed for highly polished surfaces as well as denser surfaces such as granite, marble and bluestone. Due to the structure of dense or polished stone surfaces, Deepshield™ GOLD is the best product for the job.
Is one coat of sealer enough for granite, marble and bluestone?

When sealing a very dense stone such as granite, marble or bluestone, one coat is usually sufficient depending on the degree of the stones' porosity. Most stone and grout will require two coats. A few of the more absorbent stones may require additional coats to be properly sealed.
How do I know if my stone is sealed or not?

An easy way to find out if your tiles are sealed is to carry out the water test. Place a tablespoon of water on the treated surface for 20 minutes, remove the water with a tissue or cloth, pressing hard to soak up any water in the texture of the surface. If the water is absorbed or leaves a dark mark, the surface needs to be sealed, otherwise the surface is adequately sealed and does not require further sealing.
How often do I need to seal my stone?

Deepshield™ Transparent Penetrating Sealer protects natural stone for up to 10 years from both water and oil based contaminants. If you sealed your tiles or stone with Deepshield™ GOLD and have properly maintained your surfaces the sealer should last up to 15 years. The longevity can vary depending on the type of stone, tile or grout, the location and what type of wear the surface is exposed to.
What can I do to keep my surfaces looking new after sealing?

To keep your tiles and grout looking new, it is recommended cleaning each week using a pH neutral cleaner to remove any dirt or grime. Strong detergents (strong acid or alkali) may affect the sealer, mild detergents and pH neutral substances are strongly recommended.
How do I compare impregnating sealers?

There are three main factors that set impregnating sealers apart. The carrier, the expected lifetime of the sealer and the depth of its penetration below the surface. A good depth of penetration will help provide longer lasting protection for your natural stone against traffic wear and weathering.
Will Deepshield™ build up, crack, peel, or discolour?

No. Deepshield™ will penetrate and bond to the pore structure of your surface. It is not a surface coating and will not crack, peel, yellow or discolour at any time.
How can I buy Deepshield™ products?

All Deepshield™ products are available from our online store, or from one of the dozens of Accredited Applicators throughout the country. Please refer to our “Online Shop” section for further details.
Should I seal marble and travertine?

These calcium-based stone types are very porous, leaving them susceptible to acidic stains. Many food products, such as lemon, wine, tomato sauce and coffee are acidic and will cause damage. Definitely seal marble and travertine after installation.
Can I use Deepshield™ GOLD on my granite counter-tops?

Yes, Deepshield™ GOLD is specifically designed for denser surfaces such as granite, marble and bluestone and performs extremely well on most other tile and stone.
How should I apply Deepshield™ sealers?

Deepshield™ should be applied liberally, using a low-pressure sprayer, lambswool applicator, bristle broom or paintbrush or roller. Whatever suits you best!
Should the sealer be water-based or solvent-based?

Water and solvent are only carriers for the active ingredients of the sealer, once the sealer is applied the carrier will evaporate and only the active ingredients will remain. You should always avoid using solvents because of health and environmental risks. Deepshield™ GOLD will penetrate highly polished and denser surfaces as well as honed and natural surfaces. Water-based sealers are easier to apply and have no toxic chemicals that can harm your health and environment.
Why is it necessary to carry out a test trial with the sealer before doing the full job?

Every surface is subtlety different. Unless you have applied the sealer to the exact same surface with the same conditions before, it is vital to conduct a small trial to ensure you get the result you are after.
Which Deepshield™ products can I use in food prep areas?

All Deepshield™ products are non-toxic and safe for use in food preparation areas.
Is there a perfect sealer that always prevents stains?

No sealer can prevent all stains all the time. The sooner any spill can be cleaned up the less likely a stain will result. Acidic spills such as juice, soft drinks or wine can actually etch and dull polished stone if not wiped up promptly. Clean your tile and grout regularly so dirt and stains don't have a chance to build up.
Will I still get some staining after sealing?

We believe our sealers are the best of their type available on the market and are used daily by hundreds of stone professionals as well as thousands of DIY home owners. However, even impregnating sealers have their limits. For instance our sealers will not stop sensitive natural stone from etching, so to minimise absorption, spillages should be cleaned up immediately.
Can I seal tiles that have pre-existing sealer on them?

All pre-existing surface sealers must be removed before applying Deepshield™ to any surface, as the coating left by the old surface sealer may block the product from penetrating the surface. You do not however need to strip pre-existing penetrating sealers as Deepshield™ impregnating sealer will pass through any other previously applied penetrating sealer.
Will sealing my natural stone make it “salt safe”?

Not completely. There is no doubt that our sealers will provide considerable resistance to the ingress of water and salt into the stone, however the treated stone will not necessarily become 'salt safe'. Rather, it becomes far more resistant to the ingress of salt.
The durability of the stone will be affected by the amount of salt already in the stone prior to treatment, the proximity to salt water, the type and concentration of the salts in the water, the type and quality of the stone and sub-soil drainage.
At Deepshield™ we believe our sealers are the best available and are easy to apply, however they must be applied correctly. With proper application our sealers can significantly improve the durability of natural stone in a salt water environment.
What is efflorescence and what causes it?

Efflorescence appears as a white deposit of mineral salts and is caused by moisture ingress. As the moisture enters and moves through the wall or floor, it dissolves mineral salts. This mineral salt solution eventually finds its way to the surface and as the water evaporates, it leaves behind a white deposit. On porous construction materials it may present a cosmetic problem only (primary efflorescence), but can sometimes indicate serious structural weakness (secondary efflorescence).
To help stop efflorescence, surfaces should be sealed with a high performance sealer as soon as practical. By using a deep penetrating, alkaline resistant sealer such as Deepshield™, the surface will be able to withstand the highly alkaline environment found in cement based-materials. Deepshield™ is completely breathable so moisture cannot be trapped below the surface.
Can Deepshield™ GOLD be used on glazed or highly polished tiles?

In most cases, glazed ceramic tiles do not require any type of sealant, as the top layer will not allow anything to penetrate the glaze. Deepshield™ GOLD is designed for very dense surfaces and unlike other penetrating sealers produces excellent results on some glazed ceramic tile. Regular penetrating sealers are unsuitable as they may not penetrate the surface completely, leaving residue on the surface and causing a bigger problem than prior to sealing.
Will sealing make my floors dirt resistant?

Sealing a surface with an impregnating sealer will make the surface stain resistant, but not dirt resistant. The sealed surface should be cleaned as regularly as other non-sealed surfaces. If a problematic substance such as sticky tree gum falls on a sealed surface, it can still be difficult to clean, but should not permanently stain the surface, as it might an unsealed surface.
Can I use Deepshield™ to seal my fireplace tiles?

Yes, Deepshield™ is water-based and non flammable, making it suitable for use around fireplace areas.
Are your products environmentally friendly?

Yes. Deepshield™ are non-toxic water based sealers and can be used indoors and outdoors, with no unpleasant odours or flammability issues.
How do I know which sealer to buy for my tiles?

The market offers many brands with similar claims. Deepshield™ sealers differ in two important ways. Firstly, their deeper penetration provides extra protection against weathering, traffic wear, efflorescence, salt attack and freeze-thaw attack. Secondly, Deepshield™ has a lifetime of up to 10 years and Deepshield™ GOLD up to 15 years.
Can I apply a topical coating to a surface already treated with Deepshield™ Penetrating Sealer?

Deepshield™ do not recommend this due to possible bond and/or aesthetic issues, however if you choose to apply a topical sealer to a surface treated with Deepshield™ please carry out a test on a sample area first to determine the result.
Will Deepshield™ change the appearance of my natural stone?

The straight answer is no. Deepshield™ seals the pores within the stones surface and does not change the feel, texture or colour of the treated surface as Deepshield™ dries invisible. The only exception to this is Deepshield™ Colour Enhancing Penetrating Sealer, which will slightly darken and highlight the character of your natural stone, providing a wet look.
