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.

About Limestone

Limestone is a sedimentary rock that forms at the bottom of oceans and consists wholly or mainly of calcium carbonate. The colour of Limestone in its pure state is white, but it is often coloured by other materials. This calcite is sourced primarily from the shells and bones of marine organisms. The sediment that builds up preserves these organisms into fossils. Over millions of years the heat and pressure cause a chemical reaction, which turns this sediment into Limestone.

Sealing Limestone

Limestone is porous which makes it prone to staining and fracturing, and therefore must always be sealed in order to help preserve its natural beauty.

Deepshield™ sealers are designed to protect, beautify and enhance the appearance of Limestone floor and wall tiled surfaces, both indoors and outdoors. Deepshield™ sealers are used to protect interior tiles including kitchens, bathrooms and other wet areas. Deepshield™ sealers are also used to protect exterior pavers, decks, driveways, and around chlorinated and saline “salt water” pools.

Deepshield™ is a fast curing water-based sealer, with no unpleasant odours or flammability problems. Deepshield™ will last up to 10 years or longer depending on application, weather conditions and the quality and abuse of the surface. Deepshield™ will extend the life of your Limestone tiles and add value as they age beautifully instead of crumbling with erosion.

How Deepshield sealer works?

Deepshield™ Penetrating Impregnating Sealer works by chemically reacting with the Limestone rock using nano-technology developed to create a protective barrier to water and oils. The active component is a molecule consisting of silicon, carbon, hydrogen and oxygen atoms. The molecule has two ends, one hydrophilic the other hydrophobic. When applied, the hydrophilic end reacts with moisture retained in the substrate and breaks away to form another compound that reacts within the masonry lattice. This reaction forms a bond that is stronger than any mechanical or hydrogen bonding of conventional film forming sealers, the exposed hydrophobic end of the molecule changes the surface energy with the result that water and oils are now repelled, but the micro pores are still open enough to allow moisture vapour to escape making the treated surface breathable.

Fully Breathable Impregnating Sealer

Limestone tiles need to be allowed to breath, and therefore it is particularly important for them to be sealed with a breathable impregnating sealer rather than being covered by a synthetic or urethane sealer. Deepshield™ sealers are fully breathable penetrating impregnating sealers that allow water vapour to escape freely so the surface can breathe and dry out, this helps avoid harmful moisture buildup inside the treated Limestone material.

Water, Oil & Stain Protection

Limestone tiles have a serious defect, they are porous. Water and oil soluble contaminants can be readily absorbed initiating a process of deterioration, starting with efflorescence, salt damage, mould and mildew, and eventually erosion of the surface. By using Deepshield™ penetrating sealer you protect your investment and keep your tiles looking great for many years to come. Deepshield™ also acts as a salt barrier, making it ideal around saltwater pools or marinas.

Keeps your floors non-slip

Deepshield™ sealers do not affect the slip resistance of the surface as they do not leave a film or coating, therefore sealing your Limestone floors with Deepshield™ will keep your non-slip Limestone tiles non-slip. Deepshield™ sealers are not designed for slippery surfaces and will not penetrate the surface of highly polished Limestone tiles.

Non film forming, will not flake or peel

Deepshield™ is Alkali resistant, odourless and non film forming, meaning that it does not create a film or coating on the surface of the tile, as the sealer will penetrate into the pores of the tile. Deepshield™ sealers will not flake or peel, and do not need to be removed before reapplying in the future as topical and other film forming sealers do.

Protecting Limestone from Acid Etching

Acid etching is different from a stain, as etching makes the stone material look like is has been eaten or that is has corroded and may even cause deep pitting. Acid erodes the stone, leaving dull marks on polished surfaces. Acid etching can’t be cleaned and can only be removed by honing or grinding the surface. Acid etching on Limestone is commonly caused by direct contact with liquids like lemon juice, cola, wine, vinegar and champagne. The milder the acid, the longer it takes to etch the stone, stronger acids can cause dramatic damage in seconds.

Even when Limestone is sealed, acidic substances should be cleaned up as soon as possible as it is very difficult to seal Limestone against acid attack. Limestone, like other calcite based natural stone is prone to acid etching. Limestone is immediately etched by any acidic material on contact, which is one of the reasons behind the popularity of the honed (matt) look Limestone, as it doesn't show the matt etch marks as much as polished Limestone.

Pre-Sealing Preparation

  • 1. Any surface to be sealed should be clean and looking just as you want it before sealing, as it may be near impossible to remove stains left in your Limestone before sealing without having to hone the surface of the Limestone tiles.
  • 2. must have no other coating such as wax or a topical sealer before Deepshield™ is applied, all coatings must be removed before sealing with a Deepshield™ sealer.
  • 3. Acidic cleaners should not be used on Limestone as they will damage it.
  • 4. Limestone surface must be dry before applying any sealer.
  • 5. You must do a test on a small, inconspicuous area of your Limestone tiles at least 24 hours before sealing the rest of your tiles.
  • 6. When using Deepshield™ Colour Enhancer your must also test to check if the sealer has produced the colour enhancement that you desire.

Frequently Asked Questions

+
Why seal limestone?

Building materials such as limestone are made up of countless capillary pores, allowing for the absorption of liquids such as water, water-borne salts and oils. These liquids cause limestone to deteriorate prematurely and in doing so reduce its usefulness. Examples of deterioration include; unsightly staining, weathering, loss of strength, efflorescence, salt attack, sulphate attack, biological attack, chemical attack, swelling, embrittlement and picture framing. Sealing your limestone will help eliminate or significantly reduce most of these problems.
+
Will Deepshield™ make my limestone slippery?

Deepshield™ will not affect the slipperiness of your surfaces and does not cause any yellowing or leave a visible shine. Deepshield™ is suitable both indoors and outdoors and is ideal for use around swimming pools and other wet areas.
+
How do I know if my limestone tiles are sealed or not?

An easy way to find out if your limestone tiles are sealed is to carry out a 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.
+
What is the difference between Deepshield™ GOLD and Deepshield™ Transparent Penetrating Sealer?

Highly polished surfaces and dense materials 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, providing protection 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 can happen if limestone is not able to breathe?

Stone has a porous internal structure. Moisture present in the ground can be wicked or drawn into limestone 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 can take the form of pitting, spalling, flaking and oxidation.
+
What is the difference between Deepshield™ Transparent Penetrating Sealer and Deepshield™ Colour Enhancing Sealer?

Deepshield™ Transparent Penetrating Sealer bonds to 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 give a “wet look” while not affecting the surfaces slip resistance properties. Deepshield™ Transparent Sealerand Deepshield™ Colour Enhancing Sealer protect against water and oil based stains for up to 10 years.
+
What is the difference between an impregnating sealer and a topical sealer?

Topical sealers produce a physical barrier over the limestone surface which also results in a darkening, yellowing or glossy coating. Surface sealers (topical) usually don't last as 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.
+
Is it enough to maintain limestone by just applying Deepshield™?

No. Deepshield™ sealers provide a preventive measure that gives extra protection to your limestone, which still needs to be maintained with stone care products once sealed. Deepshield™ will last longer and work better when the limestone is properly cared for. In addition, periodic professional maintenance such as cleaning, polishing and repairs are definitely recommended.
+
How can I check to make sure I have applied Deepshield™ effectively?

As Deepshield™ doesn't alter the appearance of the limestone, you wont be able to check just by looking at the surface. The easiest way to measure the strength of the seal is to apply a teaspoon of water to the surface and see if the colour beneath the water darkens after a few minutes. If the limestone darkens, that means that moisture has penetrated, and a fresh coat should be applied.
+
How often do I need to seal limestone?

Deepshield™ Transparent Penetrating Sealer protects limestone for up to 10 years from both water and oil based contaminants. If you sealed your limestone 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 limestone looking new after sealing?

To keep your limestone 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.
+
Will Deepshield™ build up, crack, peel, or discolour?

No. Deepshield™ will penetrate the limestone and bond to the pore structure. 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.
+
How should I apply Deepshield™?

Deepshield™ sealers should be applied liberally, using a low-pressure sprayer, lambswool applicator, bristle broom, paintbrush or roller. Whatever suits you best!
+
Why is it necessary to perform a test trial 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 as 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 limestone sealer that always prevents stains?

No sealer can prevent all stains all the time. The sooner any spill can be cleaned the less likely a stain will result. Acidic spills such as juice, soft drinks or wine can actually etch and dull stone if not wiped up promptly. Clean your tile and grout regularly so dirt and stains don't have a chance to build up.
+
Can I seal over limestone with a pre-existing sealer?

Pre-existing surface sealers (topical) must be removed before applying Deepshield™ as the coating left by the old sealer may block the product from penetrating the surface. You don't however need to strip pre-existing penetrating impregnating sealers, as Deepshield™ will pass through previously applied impregnating sealer.
+
Can I apply a topical coating to a limestone surface 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 over a limestone surface treated with Deepshield™ please first carry out a test on a sample area to determine the result.
+
Will Deepshield™ change the appearance of my limestone?

The straight answer is no. Deepshield™ dries invisible, sealing the pores within the stones surface without changing the feel, texture or colour. The only exception to this is Deepshield™ Colour Enhancing Penetrating Sealer, which will slightly darken and highlight the character of some stone, providing a wet look, without altering the texture.
