Resealing Slate Floors in Newtown

Slate is a foliated metamorphic rock which is derived from shale and consists mainly of grains of mica and quartz. Excellent exterior paving stone. Higher absorbency varieties are not suitable for exterior areas in freezing climates. Most slate is gray to black, but the rock may be red or purple, depending on its mineral content. The surface of slate is generally uneven and cleft planes can spall, due to the cleaving of the stone along its layers. Has low to medium absorption of oils and other liquids. Should be sealed with an oil-repellant penetrating sealer to prevent staining and reduce soiling. Because of the cleft planes and strong possibility of spalling, it should never be cleaned at pressures above 800 PSI and then only if the grout is in good condition.

Slate typically comes from Brazil, Vermont, China and India. The Brazilian and Vermont slates tend to have a low absorption rate, while Indian and Chinese have variable absorption rates. The softer slates need more attention with sealants before and after installation than do the harder slate tiles. Slate is a metamorphic rock, starting as a sedimentary rock and with pressure and temperature over time became slate. Because it has some porosity, you may want to seal it to keep it from staining.

A bit more about the origin of your slate will help you determine how you want to treat it. Brazilian slate is typically dense and has variegated colors while Vermont slate is typically dense, smooth and one consistent color (black, blue, green red). In contrast, Chinese and Indian slates are typically variable in density (soft to hard) and variegated coloring, with a wide range of colors. If you get a soft slate, typically Chinese or Indian, pre-seal with a porous stone sealer.

Some Indian and Chinese slates will flake and powder from foot traffic. This is not rust or other minerals coming to the surface. These are spots of softer material becoming loose particles. Some slates may be quite hard, but have a soft spot that can powder out. Some black and brown slates (if unsealed) can lose color from aggressive cleaning.

You have just finished laying slate floor tiles so the next thing you will probably think about is sealing slate. Is sealing slate necessary and does it make a difference to the look. There is lots of advice around about sealing slate but you are better off sealing slate than not. We also think that using a slate sealer enhances the look of slate and depending which one you use you can get a dull or shiny finish.

Who do you listen to when the many different types of slate used will give different results you could draw from? The best is listen to the experts and there are no better experts than those at Tile Cleaners ®.

We at Tile Cleaners ® recommend that you seal your slate floor as this will give your slate and grout the maximum protection, especially if you want to keep the natural look and feel of the slate. Also, sealing slate is important if you want a shiny or matte finish.

Slate tends to have variable absorption rates. Softer slates need more attention with sealants before and after installation than do harder slate tiles. Because slate is a metamorphic rock, starting as a sedimentary rock it has some porosity so sealing slate will keep it from staining.

What look do you want your slate floor to have - natural, wet, or glossy? You can get the wet-look without going glossy by choosing the right finish. There are finishes that will look natural after application, but many people love the wet-look for their slate floors.

Slate is quite dense, but it is still highly porous - a tablespoon of water left on the slate for about 30 minutes will leave a deep mark. Slate should definitely be sealed to keep it looking good for a long period of time.

Since slates tiles can naturally look kind of drab but there are various sealing solutions designed to enhance the color and apply a glossy finish to them.

There are three main types of sealing options available for slate tiles.

• Impregnating clear / transparent sealer.
• Color Enhancing Impregnating sealer.
• Topical glossy sealer.

An impregnating clear sealer will protect the slate and grout from water based and oil based stains. You probably can see how porous natural slate is just by applying a drop of water to the slate surface and see how the slate absorbs the water. You can imagine how any type of water based stain will be absorbed by the slate tile surface and also the grout. Therefore an impregnating clear sealer will protect the slate surface from absorbing stains and make it easier to clean the slate and the grout.

Both water based sealers and solvent-based sealers can be used on slate. However, unless needed for a specific reason, we always recommend using water based sealers as they are do not produce smelly fumes on application and removal, and they are a lot easier to apply and remove, and take less drying time. In fact, solvent-based sealers are now banned in many parts of the world, including most of Europe.

It is however important to know which type of water based sealer to use on your slate tile, which also depends on wether they are inside or outside, as most sealers will not last long outside as they are designed for internal use. So if your slate is outside, it is important to use a water based sealer that is specifically made for outdoor slate.

You should always ensure that the tiles themselves are completely clean, before you attempt to seal up the tile. This will protect the appearance of the tile, and help to be sure that there won't be any dirt or other debris caught under the layer of sealant.

After you have applied your last coat of penetrating slate tile sealant, let cure for at least 24 hours before walking on the floor. The longer you can let it cure before walking on it, the better protection you will have, and the longer the finish will last.

Topical sealers (glossy plastic coating over the top of the slate) are still used on slate, but these older style sealers can trap moisture in the stone and make the surface very slippery when wet. Plus, when a topical sealer wears in higher traffic areas, the entire surface has to be stripped and re-sealed,

To provide premium protection from oil and water-based stains, maintain the look and slip resistance of the slate and prevent damaging moisture from being trapped within the stone, it is important to seal slate with a high quality, invisible, fully breathe-able impregnating sealer.

Our Slate Floor sealing service will protect your slate tiles and keep them looking fresh and new.

After you grout the tiles (preferably with latex grout because it increases flex strength, reduces efflorescence, and has great bond strength), let it dry, ideally for a week, before cleaning the tiles. You want to wash the tiles thoroughly, several times, to remove all remnants of excess grout so that it won't become a permanent part of your slate floor. When the tiles are dry from the washing, you can apply two more coats of penetrating sealant. This step is to add further protection to the slate, but also to the grout and grout-tile interface.

To seal or not to seal? Go for it with a penetrating, water-based slate tile sealer and enjoy your natural stone floor for years.

When it comes to stripping sealer off slate tiles, what type of sealer was used to seal the slate tiles prior makes a big difference to how to strip it. In general, if your slate tiles were previously sealed using a water based sealer, then it should be relatively easy to strip the old sealer. However, if solvent or poly urethane sealer was used, then this job can be very time consuming, and usually requires the use of very special toxic products, so you should always call a professinal to do this for you. Here at Tile Cleaners ® we offer our slate stripping and resealing services all around Newtown.

There are two types of impregnating clear sealers, Water based clear sealer & Solvent based clear sealer. In the past solvent based sealers were used as they used to absorb deeper into the slate and grout and used to last longer. However today with all the new advanced types of quality water based sealers available in the market, it is reccomended to use water based sealers only, which typically have less of an odor when applying and removing.

Applying a solvent based clear sealer can be much more difficult to apply and can cause major problems if applied incorrectly, and is also alot harder to remove. We reccomend the use of water based sealers in most cases.

At Tile Cleaners ® we generally recommended to our clients the application of a water based sealers to their slate tiles and grout.
