Floor sealing and protection

Natural stone floors such as marble, travertine, limestone, terrazzo and granite are a long term investment in the look and value of your property. To keep them looking their best, they need more than regular mopping. Professional floor sealing and protection is essential to defend the stone against stains, moisture and daily wear. Stone Guru provides specialist floor sealing services in London and the surrounding counties, helping homeowners, property managers and commercial clients preserve their stone surfaces for many years.

Why floor sealing is essential for natural stone surfaces

Stone is a naturally porous material. Without a suitable sealer, liquids, oils and dirt can penetrate the surface and cause discolouration, marks and permanent stains. Everyday products such as wine, coffee, cleaning chemicals and limescale can etch or dull the finish. High foot traffic, trolleys and furniture can also wear away unprotected surfaces and make them harder to clean.

By applying a professional grade stone sealer, we create an invisible protective barrier that reduces absorption and makes day to day maintenance much easier. Proper sealing helps to stabilise the colour, protect the structure of the stone and extend the life of any polishing or restoration work previously carried out.

Our floor sealing and protection process

Each floor is different. At Stone Guru we start with a detailed assessment of the type of stone, the age of the installation, the current finish and the way the space is used. A busy hotel lobby or retail area requires a different protection system compared to a residential hallway or open plan kitchen.

Before any sealer is applied, we carry out a thorough deep clean using specialist equipment and stone safe cleaning agents. This step removes dirt, residues, old sealers and contamination from the surface and pores of the stone, ensuring that the new protective treatment can bond correctly.

We then select the most appropriate sealing system for your floor. Depending on the material and the desired appearance, this may be a penetrating impregnating sealer that works within the stone or a surface coating that offers an additional layer of protection in high traffic areas. Our products are chosen to provide durable protection while keeping the natural look of the stone.

The sealer is applied evenly, in controlled conditions, and allowed to cure for the recommended time. When required, we finish with polishing or buffing to refine the appearance and achieve the right level of sheen, from natural matte to a higher gloss, always respecting the original character of the stone.

Stone types we seal and protect

We work with a wide range of natural stone and engineered stone surfaces. This includes polished, honed and brushed marble floors, classic and tumbled travertine, limestone in light and dark tones, terrazzo floors in residential and commercial settings, granite tiles and slabs, as well as other high quality stone finishes. Whether your floor is newly installed or has recently been restored through grinding and polishing, our floor sealing and protection service helps to lock in the result and keep it stable in daily use.

Benefits of professional floor sealing

A professionally sealed floor offers clear advantages compared to an unsealed or poorly sealed surface. Spills have less time to penetrate and are easier to wipe away, which helps prevent staining. The stone is better protected against moisture and chemical damage from cleaning products. The surface tends to stay cleaner for longer because dirt does not bond so easily, reducing the effort and frequency required for routine maintenance.

For commercial spaces, correct sealing can also support health and safety by making professional cleaning more effective and helping the floor maintain a consistent, easy to inspect appearance. In residential properties, clients appreciate the way a sealed floor keeps its colour and finish, particularly in kitchens, bathrooms and entrance halls where exposure to moisture and dirt is higher.

Floor sealing after grinding, polishing or restoration

Many of our clients choose floor sealing as the final step after a full stone floor restoration. Once we have levelled, ground and polished the floor to remove scratches, lippage and dull areas, sealing is applied to preserve the new finish. This is especially important for marble, travertine and limestone, which are more sensitive to staining and etching in busy households or commercial environments.

If your floor has been restored in the past but the protection has worn away over time, we can also provide a maintenance clean and re sealing service. This refreshes the protective layer and helps avoid the need for a more invasive restoration process.

Maintenance plans and aftercare advice

Correct day to day care is essential if you want the sealer to perform for as long as possible. As part of our floor sealing and protection service, Stone Guru provides clear aftercare recommendations, including which cleaning products to use, which to avoid and how often to carry out maintenance. For larger homes, apartment buildings or commercial sites we can set up a regular maintenance plan to clean, inspect and re seal selected areas as needed.
