Our “most-asked” questions are answered on this page. However if you have a question that isn’t answered here, you can either check out our full FAQ list, use the online help to ask us in person, or phone or email your question in. We’ll do our best to answer any new questions within one working day.
1. How should I clean my stone / tiled floor?
Most people clean with sponge or string mops, leaving the tiles very wet on completion. This moisture will eventually soak in the tiles or grout joints, discolouring them. Microfibre mops (used damp, not wet) pick up dirt and grime from the floor, and do not leave moisture behind that can cause these problems. They are effective at removing dirt, grime, and bacteria, and can be used chemical free. Slique recommends Microfibre mops and cloths for stone and tile maintenance.

2. Why does my Marble bench / vanity have dull marks?
Marble (and limestone) are very sensitive to acids, which can etch into and dull the stone. These acids can come from fruit, alcohol, soft drinks, soaps, shampoos and so on. Slique are able to remove almost all etch marks to return the stone to an even gloss or honed finish, and can help with treatments and tactics to avoid future damage.
3. There is a white encrustation coming through my deck’s grout joints, what is it?
The build up is known as efflorescence. It occurs when water penetrates under the tiles (usually through cracks in grout joints) and picks up a mineral. This mineral is then deposited on the surface of the tile or grout when the water evaporates into the atmosphere. Slique are able to remove the physical build up of efflorescence, and can help advise structural changes to limit future growth.
4. Do I need to seal my porcelain tiles?
The word ‘porcelain’ can be used to describe a huge array of tiles, making this question extremely difficult to answer. Generally matt finish porcelains do not need to be sealed, whereas polished porcelains almost always should be sealed. These are not concrete rules however. Slique is happy to test your porcelain to let you know if a Stain-Guarding treatment could benefit your situation.
5. Why is my outside sandstone / concrete / limestone getting mouldy, and how can I remove the mould?
Even when stone is sealed mould and algae can form over time, generally in areas where water is pooling, or in areas that do not receive regular sunshine. Once the stone had the mould and algae removed, a high quality penetrating Stain-Guarding treatment should be applied to reduce moisture penetration. At this point a regular bio-cide application (slow release mould killing product) can be applied as required to control mould. These products can be applied by Slique, and there are some very good off-the-shelf products that you or your landscapers can use.

6. Can I water blast my stone?
No, water blasting can cause structural damage to stone, roughing its surface to change its appearance, and speeding up the growth of mould and algae. Water blasting will also damage the integrity of most Stain-Guarding treatments available. Soft washing with low pressure is an acceptable alternative.

7. Why am I getting a white build up on the tiles in my shower?
When water (especially with body wash or shampoo residue) dries on the surface of a tile (or glass) it will leave a residue behind that can often be difficult to remove. To help avoid this rinse the glass and tiles down with clean water, and dry with a squeegee.
8. I want to seal my floor myself; can you tell me which product to use?
Unfortunately there is not one miracle sealer that works extremely well on all different types of surfaces. Sealers are chemically designed for certain types of stone in certain situations, so without knowing all the details it is very hard to recommend a product.
