After one of my parent's fell in the bathroom, I have been scouring the internet for something to protect them. We didn't have an ability to change the flooring, so we needed a coating which would keep them safe and not ruin the floor's appearance. (That was very important to them!) A friend recommended Safety Direct America and their products. I ordered the Sparkle Tuff and was able to apply it myself.

It's been two years now, and even when the water has leaked from the shower and the floor is wet, my parents are safe because of this coating. I could not recommend it more. It is easy to apply and takes away any concerns of accidents. I've applied it to my slippery deck and garage floor. It looks great and keeps everything safe and anti-slp!

Hi John, I installed the "SPARKLE TOUGH" two days ago, and used the shower for the first time an hour ago, (hope that wasn't too much information for you). What a fantastic product, I really tried to soap up the floor, and have a failure, but it works just great, even better than great.! Thanks for your help in the previous emails, they were very helpful, and I'm very pleased. Thanks again and have a great year. Gary Ewing

For Floor slip resistance testing, these guys are the experts. If you need to know the truth about the slipperiness of a floor, this is where you must go. Look no further, they are the BEST!

We purchased and applied SparkleTuff Anti-Slip Floor Coating to our shower floor last June. It is truly an AMAZING product! It has totally change the our sense of security when showering. The floor is no longer slippery yet it is very comfortable at the same time. t was easy to apply - just follow the directions. It does not change the look of the floor (no yellowing). So, it's been over 6 months and it is holding up beautifully. Buying this product has saved us so much money (we looked into having the floor tile replaced -super expensive and no guarantee). I'm a physical therapist and have seen so many patients who have fallen on slippery surfaces. I didn't want to be one of them;) Do not hesitate to buy this. It's fantastic!

I'm Very Disappointed in the Coarse Non-Abrasive Anti-Slip stick-on 6" x 24" rectangles purchased for my bathtub. I waited 24 hours after applying them but as soon as water hit, they raised up in the center & could not be stuck back down again. I was told i needed to return them within 7 days? This company sucks. I blew $36 & now have a tripping hazard in my tub. Their website is also terrible: very hard to find what you are looking for. I tried to do a good thing & support a small company, but I'll shop elsewhere from now on.
