GAME CHANGER!!! We had an old tile floor that had a high and low sheen finish. The floor always looked dirty like someone had walked on it with a sticky substance. We have about 1400 sq ft of tile flooring on the ocean and to replace all of the tile was not in our budget. Luckily my girlfriend found the CoverTec website. Based on reviews, I chose to try the matte finish. The product was easy to apply although it did take a bit of a toll on our 70-yr old muscles with the up and down movements necessary to make sure the floor was cleaned well and to edge and role the tile surfaces. I would recommend breaking your project in smaller sections to avoid muscle fatigue. Drying time took about 24 hrs but we feel that was probably due to moist ocean air. Covertec's product coverage numbers are very generous; I ordered 3 gallons to be safe but probably could have completed the project with 2 gallons. Customer service is outstanding! Special shout out to Charles who was always prompt to answer my application questions and even did so on the weekend.
