Product description

Black Diamond Stoneworks Natural Stone and Grout SHOWER SEALER is an innovative, professional-quality penetrating sealer that will protect your natural stone shower and grout from the damage of water, soap scum, and calcium. Keeping the surfaces looking beautiful and easy to clean. Use on marble, granite, travertine, limestone, and grout. Our SHOWER SEALER can perform up to ten years on some applications, but we recommend re-applying between 5-7 years to ensure the best results. DIRECTIONS: Before applying, the surface must be clean and dry. To remove soap scum, use our Natural Stone Soap Scum Remover. When sealing natural stone showers, start on the walls from the top down. Spray the SHOWER SEALER on one wall until completely wet. To help the sealer penetrate and to keep it from running off onto the floor it is recommended that you use a paint roller, paint pad, or the scrubbing side of a sponge to work the sealer over the surface for 5 minutes. If the surface begins to dry before 5 minutes is up spray more sealer on it and continue to work, it into the surface for the remainder of the 5 minutes. COMPLETELY dry the surface after 5 minutes. If you do not completely dry the surface it could become tacky and slippery when wet. Move on to the next section and repeat. To achieve the best performance, a second coat should be applied after 20 minutes. Wait for 24 to 48 hours before getting the surface wet. When sealing grout in tile, follow the directions above but you only need to spray it and work it into the grout lines. Do not worry about the tile as it will wipe up when you are done, just do not let it dry on the tile. COVERAGE: one quart will seal two large showers

Not sealing marble properly.

Not sealing marble properly.
I am only writing this review to help someone with expensive stone not lose thousands of dollars with this product. We generously applied it exactly like the instructions. It didn’t really do a good job sealing. 9 months later water has gone through it and destroyed our marble. Now we should rip everything out and re do.

    Looking for the right sealer? This is the one! Works the same as original one used by the pro in a shower. Just clean the grout with hard brush and give 2 coats of it as per instruction. Wait 2 days to dry up and will be ready to use! Make sure to clean your tiles when still wet so there won't be anything left on them after.

    I purchased this product and was only able to complete 1 1/2 showers. The listing and label say there is enough for 2 showers. I followed the directions perfectly. Now I have an incomplete job needing more product and more drying times. Not happy.

    J’ai appliqué le produit dans la douche de céramique et dans l’évier. Facile à appliquer. Seul inconvénient est le délai pour lequel la surface doit rester sèche après l’application, il faut donc bien prévoir.

    Does the job 100%. We bought an older home, and water going thru grout and tile. This stopped it. And changed from sn old shower to one that look brand new. No more seeping.

    Two coats does really well. had to use a buffer to clean overspray and it was a little work. That goes to show how good it is doing on the grout. Normally you can wipe it off with a wet rag but not in this case.

    Cleaned the shower with the cleaner, and applied as directed. When applied I was sure it was a waste of effort and time. WRONG! It did work and has worked. Doing a fantastic job of nearly eliminating the time needed for shower cleaning. Honestly I could not be more impressed with a product. Does what it says it will do. Keeping life easier to maintain and enjoy. Was looking at purchasing the color enhancer but this product brought out the depth of the stone and left me with the look I was going for, while providing years of protection.
