ElaSticone GSX

ElaSticone GSX is an invisible protective treatment formulated to protect masonry and stone surfaces from water, oil, graffiti and more. This product is designed for high-performance building restoration and preservation applications. 


This product is based on an inorganic skeletal framework that when combined with a fluoropolymer creates a clear, penetrating barrier that will protect surfaces against oil and water stains, graffiti and more without altering the surface appearance of the stone. It is designed to penetrate the surface and react with the silica within the stone, expanding and filling cracks and crevices in the material to create a long-lasting repellency to water and dirt. This treatment will help to deter unsightly stains caused by mold and mildew. Surfaces treated with this product can be easily cleaned using a mild detergent such as Presto’s Green-Kleen®.

Always test in a small, inconspicuous area prior to use. Use any of Presto’s stone cleaning products to ensure the stone is completely free of all dirt, staining and biological growth. Make sure to thoroughly rinse the material to ensure no product is left behind on the surface prior to sealing. Any cleaning product left on the surface can interfere with the protective coating. 

Complete all caulking and surrounding construction substrate applications prior to use of this product. Newly installed stone or grout must be allowed to cure before application. Protect against personal contact with this and all chemical products.


Use protective gear to prevent personal contact. Use a lowpressure sprayer, roller, brush, sponge or lambs wool applicator. Product may also be back rolled. Do not dilute; apply full strength. Never apply to a damp or wet surface. Do not apply at below freezing temperatures. Protect any unintended areas. Apply product to create an even coat on the surface. Allow product to saturate surface. Do not allow product to pool on the surface and dry, or protection will be uneven and a residue may form. Remove any excess material by use of a rag or towel. 

A second coat may be needed for porous, absorbent surfaces or for superior protection. Subsequent coats should be applied in the same manner as the first while the initial application is drying. Never apply a second coat if two coats were not tested and approved prior to use. Protection will begin immediately after sealant dries on the surface. Cure time for maximum water and stain protection is 24-72 hours.

Protect surface from contact with water for at least 48 hours. Application rates, concentration, temperature and humidity can impact dry and cure time. Use towels or rags to polish the surface and remove any excess product. 

In many instances, a combination of different stone cleaning products is necessary for various stone surfaces depending on their level and type of staining. Presto offers a complete line of stone cleaning products for all situations, including:

  • Stone Restore® HD For difficult to remove mineral stains caused by efflorescence, rusting, red clay, iron, and more

  • Stone Restore® NC For general cleaning of sensitive stone surfaces that require a neutral cleaner

  • Stone Restore® A+ For heavy stains caused by oil, grease, grime and environmental pollution

  • Stone Restore® CT A citrus multi-purpose stone cleaner that removes oil and a variety of stains

  • Stone Restore® CB2 For difficult to remove biological stains

  • Stone Restore® PS For stubborn surface contamination on all types of polished stone 


Clean tools and equipment with mineral spirits. In the event ElaSticone GSX is allowed to come in contact with adjacent surfaces, dries and is difficult to remove, use any of the following surface restoration products: 


For ongoing maintenance of the protected surface, we recommend the use of Green-Kleen diluted 10 to 1 with water, preferably heated deionized water. Apply the diluted product to the surface. Allow to sit for one or two minutes and scrub with a soft bristle if necessary to remove build up. Then gently rinse the surface clean with low pressure. For exterior vertical surfaces, we recommend cleaning the surface every 2-3 years in order to retain a clean appearance and preserve the previous restoration. High pressure is not needed and may damage the surface coating or weaken its performance. This maintenance cleaning is not mandatory to ensure the coating will last as stated in the warranty and is only a recommendation.

After cleaning or sealing stone surfaces, the glass windows and metal frames almost always need to be cleaned, and many times window spots and stains will need to be removed as well. View our glass and metal products that compliment our stone restoration and protection products.
