Customer Reviews for Roman Piranha 1 gal. Liquid Concentrate Wallpaper Remover

I scored the wallpaper and waited 15mins for this stuff to soak in. The wallpaper did not come off. I tried it again after letting it soak for 2 hours. The wallpaper is still stuck to my walls. I'm going to get a steamer instead.

Worked as expected. Easy to spray on and cleanup was easy, too.

we are professional wall covering installers. This product works great for adhesive residue on seams. Use HOT water with concentrate and then rinse with HOT water!

This is a gel that you apply after scoring the wallpaper. I had much better results using a brush and really putting a thicker coat on. I left on for at least 20 minutes, and then checked to see if it was starting to release paper. If not, I applied another coat of gel. Now this is still hard work but I found this to be lots less mess than the steamer. I would use again in a heartbeat.

The product had no spell and appeared nontoxic. The directions were easy to follow. However, when I attempted to find this product online there were no directions as to how to discard remaining liquid. I followed directions accordingly. Not once did this product do what it was suppose to. Most of the time I was only moving border paper. I spent 5-1/2 hours moving wall paper on a 5 x 8 ft. wall. I would never buy this again. BACK TO THE DRAWING BOARD BOYS!!!!

Worked great. Just make sure you spray enough and wait for 20 minutes

Spray on product so it runs down the wall and pools on the floor. It takes more than two applications to remove the wallpaper. Now I'm trying to work with a gel plus this product.

Very good product. Loosens and allows the removal of the toughest wall paper. I wish HD continued to carry it in the store.

I've used this product several times on both paper and vinyl based wallpaper and it's worked great. You have to make sure you use very hot water when mixing / applying the product. It's also a good idea to use the dimple tool that puts small holes in the paper to aid in water penetration. Soak it good and wait 15 minutes - apply another coat and let soak another 15 minutes on stubborn paper and it will come off nicely. I have had some issues trying to remove paper that was put up on drywall that was not painted first. In these cases you have to be careful in how wet you get the wall paper as the drywall paper will get wet too. A steamer in those cases might work better.

Worked ok.

It is the best wallpaper remover on the market.

Love it- spray on let it set for about 3 minutes- peel off so easy...

This is the first wallpaper remover I've found that actually works! I managed to strip 40+year old wallpaper with no major hassles. Doesn't smell, doesn't make a mess! Great product!

doesn't dissolve the glue and allow the paper to come off without damage to the dry wall. M-1 worked much better
