With a density of 0.80 g/ml, it penetrates deeply into natural and engineered stones like granite, limestone, and terrazzo, providing a transparent, anti-stain protective layer that activates within 24 hours. Easy to apply and recommended by professionals, it ensures long-lasting surface protection and enhanced stone aesthetics. ## Description This solvent based sealer for stone is made by Tenax in Italy and this product represents the best value for sealing natural stone in tests. It tested very good for granite (including the exotic granites), and it works on limestone, sandstone, terrazzo, concrete agglomerate, and even engineered stone. he product must be evenly applied on dry and clean materials. The presence of water, dust or dirty matter may influence the result regarding the uniformity of the surface. We suggest to spread the product using a brush, sponge, cloth or with a spray gun. Use the right quantity that the material naturally can absorb. Then, after few seconds, clean (buff) the surfaces with a clean cloth. The excess may create a superficial sticky film, so the excess must be removed immediately after the application. We suggest to repeat this treatment after 10-15 minutes from the first application. The effect of anti-stain will be achieved after 24 hours from the treatment. In case of floor application, do not walk on the surface before. Ships to the continental U.S. only. Review: Failure - This thing didnt work as described Review: Great product. Went on very quickly and easily. The odor was too strong for us but it went away within a half hour of opening the windows. I sealed my granite tops a month ago and the shine and protection is great. A pro finisher recommended Tenax Proseal and I know why. Forget the water based junk. ## Features - From an Industry Leader - Density at 25°C gr/ml: 0,80 - Aspect: liquid - Standard Colour: transparent/opalescent - Perfect for commercial and industrial applications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00SC8SCYS | | ASIN | B00SC8SCYS | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #73,324 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #432 in Hardware Sealers | | Color | Transparent/Opalescent | | Customer Reviews | 4.4 4.4 out of 5 stars (240) | | Customer reviews | 4.4 4.4 out of 5 stars (240) | | Date First Available | 20 March 2021 | | Date First Available | 20 March 2021 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 259 g | | Manufacturer | Tenax | | Manufacturer | Tenax | | Material | solvent based sealer | | Package Dimensions | 9.09 x 8.51 x 7.8 cm; 259 g | | Package Dimensions | 9.09 x 8.51 x 7.8 cm; 259 g | | Size | Full Size | | Style | Industrial | ## Product Details - **Material:** solvent based sealer - **Brand:** Tenax - **Style:** Industrial - **Item weight:** 0.26 Kilograms - **Water resistance level:** Water Resistant ## Images ![Proseal Sealer 250 mL - Image 1](https://m.media-amazon.com/images/I/71wzYFomIuL.jpg) ## Customer Reviews ### ⭐ Failure *by M***A on 29 February 2024* This thing didnt work as described ### ⭐⭐⭐⭐⭐ Review *by S***M on 22 January 2019* Great product. Went on very quickly and easily. The odor was too strong for us but it went away within a half hour of opening the windows. I sealed my granite tops a month ago and the shine and protection is great. A pro finisher recommended Tenax Proseal and I know why. Forget the water based junk. ### ⭐⭐⭐⭐⭐ Review *by A***3 on 9 January 2020* I had new granite countertops put in about a year ago and the company used this same product to seal them after they got my counter set. I take good care of my granite bc it’s so expensive and just to stay on top of that I decided I would reseal them again, not necessarily bc they needed it but just to be proactive and protect them. Proseal is easy to apply with a rag although the vapor is very strong. Make sure to clean your granite first with rubbing alcohol and let dry. I would also recommend a fan nearby and open those windows to help ventilate. There is plenty solution left over to reapply for the next 2 years. Store is cool dry place and you’re good to go! ## Frequently Bought Together - Tenax Proseal Granite Sealer, Marble Sealer, & Stone Sealer -- 250 mL - (12-Pack) Professional Microfiber Sealer Applicator Pad – The Perfect Tool to Apply Sealer to All Natural Stone and Tile Like Marble, Granite, Concrete & Slate (White) - Tenax Ager Color Enhancing Granite Sealer, Marble Sealer, & Stone Sealer - 1/4 Liter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/304126927-proseal-sealer-250-ml](https://www.desertcart.pl/products/304126927-proseal-sealer-250-ml) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
