Anti-Slip Spray for Increased Grip on Fiberglass, Acrylic, Concrete and Tiles – Clear Non-Slip Coating for Shower, Bathtubs & Floors

It really works. My shower floor is exactly like my spouse's tub (that we paid a lot more money for a non-slip surface to be applied by a professional). Now I can use my sugar scrub with oils and not worry about slipping. I purchased 2 cans just to make sure I had enough since some of the reviews mentioned the can only sprayed for a few seconds. I only used 1/2 can to cover a 3.5 by 3 foot shower fiberglass floor.Respirator: Make sure to wear a respirator as this product can damage lungs. I purchased a 3M 6100 small half mask reusable respirator that came with 2 sets of 3M 2071 filters, the best $15 investment I ever made.Instructions: It didn't come with instructions, but you can print these by going to: SlipDoctors dot com -> Products -> Anti-slip solutions -> Shower Solutions -> Non-slip Spray -> Instructions.1. Make sure to clean the surface: Use a straight-edge razor to remove any traces of stuck-on gunk (in my case, it was removing the non-slip stickers), then clean with Bon Ami cleanser (or you can use Comet, etc.), wash thoroughly, wipe it dry. Then I poured acetone (nail polish remover without water in the ingredients) on a rag, and wiped it down. I allowed the shower to dry completely for about 2 hours.2. Tape off the area you want to spray with painter's tape. Make sure to tape over the drain to avoid spraying into it. Then attach newspapers (or painter's paper) about 2 feet up along the shower walls (or bathtub), and tape it down to the painter's tape. You will have to remove the paper after applying the spray, so try to make sure you attach each section of paper together to avoid any paper from falling onto the product while it's still wet.3. Shake the can vigorously for 3 minutes (making the metal ball in the can make noise to mix the product). This was a workout, as I shook both cans at the same time in case one of the cans didn't work.4. Put on the respirator! I can't stress this enough. I have permanent lung damage from not wearing a respirator during one of my other projects several years ago.5. Open any windows in the bathroom, and turn on the ceiling ventilation fan. If others are in the house, close the bathroom door and place a towel on the floor against the door. When leaving the bathroom, put the towel on the floor against the outside of the door. This will prevent the fumes from getting to the rest of the house.6. Spray the product gently back and forth about 1 foot above the surface to cover it lightly. (I went over it again with another light coat.) If a second coating is desired, you can reapply 30-60 minutes after the first application (one coat is preferred). I guess I sprayed it a little heavier than recommended, because it was still wet after an hour. I found that I didn't need a second coat. Remove the tape and paper shortly after application, but make sure it doesn't touch the wet product.7. If you have product left in the can and you want to save it for a later project: Turn the can upside down into a plastic garbage bag to release some air to clean out the sprayer nozzle.8. After 24 hours the shower should be ready to use. The smell dissipates after about 12 hours.01/21/15 update: The floor is holding up great, however, I think I figured out why the manufacturer of the shower pans makes these so darn slippery... it's to allow the water to completely drain off into the center drain. After applying the nonslip spray, my shower floor collects water and does not allow it to drain off on its own. It's as if the grit on the floor keeps the water on the floor in several places. The next morning, even after keeping the shower door open, I still have big drops of water on the shower floor. Now I have to squeegee the water from the floor into the drain after showering so it can completely dry. I keep the small squeegee hanging in the shower. I also use it to squeegee off the glass walls, which keeps the shower cleaner in between my weekly heavy cleaning.

I can not fault this product. It preforms very well providing a non-slip surface in what was a very slippery fiberglass shower base. Easy on the feet, clear in color and not too hard to apply. The one downside is has a very potent odor out of the spray can. I was fortunate to have an exterior door out of the bathroom, I set up an isolating fan, turned the bathroom exhaust fan on and wore a face mask when applying.Preparation is 90% of this job, I scrubbed the base with Softscrub, rinsed and dried it, wiped it down with denatured alcohol, then masked off the base area I didn't want sprayed about a foot up the shower walls. Be forewarned the can is under higher than normal spray can pressure, in my opinion, the product really comes out quickly, you need to be ready to move for an even spray. I gave it a second coat after an hour dry time. My shower was a 42" square and I used the whole can.We didn't even try to use the shower for 24 hours. It was totally dry then and the smell was gone.Longevity is the question now, I'll keep you posted.

Useless. Well, useless on porcelain, anyway."Wait a minute! This is for fiberglass!", you say. Yes, that's true. It's right in the name. "SlipDoctors Non Slip Resistant Spray for Fiberglass". Yep, that says "fiberglass".But in the description, it says, "Can be used on fiberglass, concrete, metal, fiberglass, tiles, VCT, porcelain and many other surfaces." Yep, that says, "porcelain".So, based on that, I asked my wife to order a can. I cleaned the tub as thoroughly as it's possible to clean a porcelain tub, short of using a strong acid. The tub was clean, bone dry, and should have been a perfect surface for this product.It went on easily enough. I used about two thirds of the can on a standard 5 foot tub. I didn't coat all the way up the sides, just the surfaces where feet might need traction, including the top outside edge. The fumes are pretty strong (like spray paint), so we left the fan running and closed the door. The product was allowed to dry over 20 hours with NO use. No problem there.I was the second person to shower the next evening, and I noticed a fist-sized patch in the middle of tub that was bare. No texture. At first I thought I had missed a spot, but when I poked at it a bit with my toe, more came off. :( By the time I finished my shower, it was coming off in sheets. Rather than let it bother other family members, I just finished taking it off, and it was NOT difficult. A slight rub, and off it came.There you go. We got less than one shower's use out of it. Maybe it's fine on fiberglass or acrylic, but it's a complete waste of money on porcelain.On another note, I was not expecting the surface to be quite so rough. It would be fine for showering, but probably very uncomfortable forbathing. Ouch.
