Sandstone Restoration

Surface Master® handles sandstone from various global sources. While sandstone can be procured inexpensively from China and India, some types may have poor quality. Hence, it is crucial to exercise caution when selecting sandstone. Surface Master® has a friendly and knowledgeable customer service team who are ready to offer any necessary advice.

Sandstone Restoration

Sandstone is a type of sedimentary rock made up of sand-sized minerals and rock grains. The composition of sandstone typically includes quartz and/or feldspar, which are abundant minerals in the Earth’s crust, as well as calcite, gypsum, and iron compounds. Sandstone has a granular texture like sand and can come in a variety of colors, with the most common being tan, brown, yellow, red, grey, pink, and white. Sandstone’s distinctive appearance often results in certain colors being associated with specific geographic regions, especially when sandstone beds form prominent cliffs or other topographical features.

Sandstone tiles can have varying levels of porosity and hardness, but on the whole they tend to be soft and absorbent. As such, it’s crucial to consistently employ proper restoration techniques to maintain their appearance and prevent water damage.

Sandstone floor tiles are susceptible to scratches, stains, and fractures. To keep the tiles in good condition, they should not be covered with synthetic seals or urethane. Surface Master® offers effective protection for your sandstone with the use of highly-penetrating, water-based impregnating sealers that form a barrier against chemical damage, deterioration, and contamination. Over time, foot traffic causes the surface of sandstone floors to become dull and lose its shine. The small scratches from daily use accumulate and dull the finish, making the surface appear less reflective. To bring back the luster and smoothness of your sandstone floor, Surface Master® utilizes high-speed polishers.

Our Surface Master Sandstone Tile Restoration services can rejuvenate your sandstone tiles and grout to their optimal state and keep them protected for a prolonged period.

Many historic buildings feature durable sandstone flooring, characterized by its chalky porous texture and smooth granular surface, a common feature of French and Spanish sandstone. Despite its durability, this type of sandstone is susceptible to staining from acidic substances, like soft drinks, and can absorb oils and other liquids. It comes in a variety of colors, including black, grey, white, yellow, and brown. To protect it from staining and soiling, sandstone should be sealed with a penetrating sealer and cleaned only with neutral pH detergents. Since it is a soft material, sandstone should not be cleaned using pressures higher than 800 PSI and only if the grout is in good condition. Regular professional maintenance is necessary to maintain the honed or polished appearance of sandstone, which is typically best with a honed or low to medium sheen finish. Some low calcite sandstone can be difficult to polish, so vitrification may be necessary, but this process can result in an unnatural plastic appearance if performed too often.

Sealing Sandstone Floors

Sandstone is known for its high porosity, with absorption varying from piece to piece. The rate of absorption can be affected by the finish of the sandstone; polished surfaces may be harder to penetrate compared to those with a honed or matte finish. To ensure optimal protection from water and oil-based stains, preserve the appearance and slip resistance of your sandstone, and prevent damaging moisture buildup, it is recommended to use a high-quality, invisible, breathable impregnating sealer.

Sandstone’s composition of calcite makes it vulnerable to acid damage from spills and its porous nature allows for oils to penetrate the surface and leave stains. To prevent these issues, sealing your sandstone with a penetrating/impregnating sealer is crucial. The sealing process will help keep most stains at bay and is the first step in protecting your sandstone from discoloration.

Two main sealing options exist for sandstone tiles

Deep Penetrating Impregnating Sealer

(Transparent Finish/Colour Enhancing Finish)

Topical Sealer

(Gloss/Satin/Matte Finish)

A premium cleaner with a deep-penetrating formula can safeguard your sandstone and grout against water- and oil-based stains by chemically bonding with the surface pores using advanced technology, creating a protective barrier that allows the surface to breathe. This type of cleaner not only protects the sandstone surface and grout from absorbing stains, but it also makes cleaning and maintenance much easier.

A transparent impregnating cleaner is designed to enter the pore structure of your sandstone without altering its appearance, while a color-enhancing cleaner can enhance and deepen the natural look of stone surfaces.

Our technicians are experts in applying all types of cleaners and will ensure your sandstone looks its best. We can also apply a topical cleaner if necessary to achieve a high-gloss, satin, or matte finish. Topical cleaners can be used to hide certain types of damage and have an average lifespan of about three years.

Pre-Sealing Preparation

Before sealing, the surface to be treated should be spotless and in the desired condition, as it may become difficult to remove stains once the sealing process is complete. Avoid using acidic cleaners on sandstone as they can cause harm. It is important to remove any existing coatings like wax or topical sealers prior to sealing. Ensure that the floor is completely dry before applying the sealer.

Protection from Acid Etching

Sandstone is prone to acid etching and other calcite-based stones such as marble and travertine are also susceptible. Direct contact with acidic materials like lemon juice, cola, wine and champagne can immediately cause etching or corrosion on the surface of sandstone. To reduce the visibility of etch marks, the honed or matte finish is commonly preferred as it shows etch marks to a lesser extent than a polished finish.

Sandstone Floor Care & Maintenance

Maintaining sandstone can be challenging if proper care and maintenance practices are not established from the start. Unlike polished marble, sandstone, which is typically honed, is less prone to scratching, but it can still lose its appeal if adequate barrier matting is not in place. The biggest concern when it comes to maintaining sandstone is the potential for staining.

Sandstone Grinding

Grinding will smooth out any rough spots and reveal a fresh layer for a honed or polished finish. It eliminates deep scratches, stains, and other impurities from sandstone, resulting in a smooth and uniform surface. Grinding also eliminates lippage, the unevenness of tiles that may occur after installation.

Sandstone Honing

Honed sandstone surfaces offer a satin-like texture that is smooth and velvety to the touch, making them ideal for creating a relaxed, comfortable atmosphere in your home or business. Compared to polished surfaces, honed finishes require less maintenance and are a great way to enjoy the beauty of natural stone without sacrificing practicality.

Sandstone Polishing

Polishing sandstone involves using progressively finer diamond abrasive discs to create a mirror-like finish. The final stages of polishing remove even microscopic scratches and enhances the natural light reflection from the stone’s surface. A highly polished sandstone floor has reduced pore size, making maintenance and cleaning easier and more efficient.

Efflorescence Treatment

Polishing sandstone involves utilizing progressively finer diamond abrasive discs to attain a reflective surface finish. The last stages of polishing eradicate even minuscule scratches, enhancing the natural light reflection from the stone’s surface. A highly polished sandstone floor has smaller pore size, making maintenance and cleaning easier and more effective.
