Sealants and Conservation

 

Water Repellent Silicone (synthetic oils): Generic synthetic oils which tend to leak from the worktop surface and travel on the worktop surface. Are of inadequate use because of their tendency of attracting dust and short life expectancy. There are a lot of types but you generally get what you pay for. This type of sealer tends to darken a lot of stone worktops.

Siliconates: Are water based silicone derivatives; they work well for light coloured and porous stone worktops. Siloconates are an affordable sealer. This type of sealer shouldn’t be used on darker coloured stone worktops or precious surfaces. Any residues not absorbed will deface the surface of the worktop with a salt-like precipitate. This sealer can be helpful for some limestone and concrete countertops and worktop surfaces. 

Damp microfiber cloth: A damp microfiber cloth is capable of picking up microscopic abrasive soils and potential staining agents. A damp microfiber cloth is recommended for most smooth surfaces on a regular basis. 

Siloxanes:Siloxanes These are very good, especially for their long life and Reasonable cost. Manly used for exterior stone surfaces like marble, granite, limestone, slate and cement based building products as well. Highly recommended for most surfaces exposed to weather and high humidity. Does not seem to darken the surface of most stone countertops. Siloxanes are Solvent based. 

Stearates: Theses are low-priced water repellent sold to consumers in large hardware stores for use on wood, concrete, masonry etc. Performance is not wonderful and life span is short. Not suggested for most building stone.

Oil Repellents: These are products, which repel oil as well as water and other liquids. There are many of these specialized products on the market and are designed for use on stone countertops/worktops. Most are fluoroplymer-based.

Drying Oils: These are the natural polymers. Most include Tung, Linseed and Soy. Drying oils go solid as they dry and are good to use for sealing stone surfaces. These oils are organic, and are sensitive to time and will go yellow with age.

Waxes: Waxes natural or synthetic and can include Carnuaba, paraffin, montan, and beeswax. Waxes are used for sealing. They are not long lasting and have to be reapplied constantly.

Silicates: Are a mineral, which fill up the pores in porous stone worktops and surfaces and help in making the worktop less porous. They work well when restoring stone, which is under chemical assault, or exterior weathering as it can repair lost minerals and provide protection from further degeneration. They are specialized materials, which require expertise to formulate and apply for good results.

Finishing Dressing:

Waxes: This category is primarily paste waxes composed of paraffin, beeswax, and some synthetics. They can be effective for maintaining a shine and avoidance of stains. Some specialized products contain dyes or pigments that can be helpful in bringing out the colour of red, black and green stones. Waxes are mainly used for furniture.
