How to repair Silestone? Care and restoration tips

Silestone is one of the best known and high demand materials in interior design and architecture. It is made from premium and recycled materials, produced through the exclusive and innovative HybriQ® technology and is the most advanced and sustainable hybrid materials on the market. This has led it to become a multipurpose option used to provide added resistance to the designs of walls, floors, showers, basins, and worktops.


In fact, unlike other materials such as granite, Silestone is not immediately impacted by high temperatures or surface stains. Hot liquids can be left on the worktop and cleaned later without a stain or mark forming.


However, although Silestone does guarantee resistance and durability, it can sometimes suffer wear and tear or damage meaning repair work is needed in order to regain its spectacular beauty and design.

How to repair damages caused to Silestone

It is important to bear in mind that Cosentino offers a 25 year guarantee on Dekton and Silestone and a 15 year guarantee on Sensa, during which time you can replace or repair any of these products under the terms and conditions included in your agreement. This guarantee covers Silestone surfaces such as worktops, tiles, walls, and flooring fitted inside your home.


In the case of there being any defects with any Silestone product, Cosentino will proceed to replace or repair the product subject to inspection. Under the Cosentino guarantee, the acquired product will be replaced unless otherwise impossible due to it being discontinued, with the replacement product being one with similar features in this case.


If the Silestone in your home has suffered any minor damages such as abrasion, cracks, or scratches, and you do not have the Cosentino guarantee, you can repair these with specially designed products and techniques. It is also commonly recommended that a surface be polished to hide any repair work carried out.


Once of the most effective solutions when repairing scratches or cracks is the grout and silica gel that you can find at DIY or construction stores. If you are unable to find this product, marble paste is also very effective for fixing a range of different issues.


In the case of the damage being more serious, the scale of the Silestone needs to be taken into consideration, as it is one complete slab and requires a lot of care when carrying out repairs to ensure that these go unnoticed. In the case of cracks, breaks, or holes, the most effective solution is to fill these with a grout solution to prevent the defect from increasing in size.


Unlike natural stone such as granite, Silestone is not a porous material that easily absorbs stains and bacteria. Due to the composition of Silestone, stains do not remain on the surface if left there over time. It also does not need to be sealed every year like granite, and therefore, bacteria and other microorganisms do not penetrate the surface.


Silestone’s low porosity means that it is also stain resistant, making it much easier to clean and care for than other materials. Its day-to-day cleaning is very simple: just apply some neutral soap and softly rub in a circular motion with a damp sponge for professional standard results after just a few minutes. Then you just need to get rid of the excess soap with a damp cloth and dry with kitchen towel.

Q-Action is a product designed to properly clean any Silestone surface. It is listed as a star product due to its strong hygienic and disinfectant properties for Silestone worktops. Q-Action brings back the surface’s shine and also cleans and dries in a matter of minutes.
