Problem: Efflorescence, Green Mold Product Used: RadonSeal Efflorescence Cleaner

"Hello, I had an efflorescence problem in my basement do to some prior leakage in my basement. I had been researching the internet for a solution to a radon problem we are having in our neighborhood. I found another product that was paint like but the cost was over $3000.00 to cover my basement.That was to much money. As I kept looking I came across your site. Your product Radon Seal was a spray on material and after watching the video on how to apply it I was sold. Not to mention for a lot less money also.

Before I start with the seal I have to take care of "That White Stuff". Back to your site. Low and behold you have a product for that too. Best of all, you spry it on and let it dry and you're ready to seal. I order 2 1/2 Gals. When it arrived I actually read the directions, hard to admit for a guy. While reading I find out that it also removes mold. I wasn't sure what that green stuff on my walls were, but I had a good idea it might be mold. After spraying the white spots, having some left I thought I'd spray a section of the wall that had the most green on it. I have to tell you I was amazed that appx an hour later when I went back downstairs the wall I sprayed was completely clean and looked like brand new.

I started spraying another part of the basement walls and decided to only spray just 1/2 of the green stuff and see what would happen. Again,about an hour later, BINGO, the part that I sprayed looked like brand new. I have to tell you, your product Radon Seal Efflorescence Cleaner is EVERYTHING you said it was. In this day and age many times we are led to believe that this product or that product is the best in the world, only to find out after buying it, that's not really the truth. Well, you guys and girls sure did tell the truth here. I actually had to buy another 2 1/2 gals to finish the rest of my basement.

Thank-You,Thank-You,Thank-You first ,for the great product you have ,and being the kind of company that tells the truth about their product. After I finish with the efflorescence cleaner I'll be using the Radon Seal to seal the walls and floors. I'm actually looking forward to doing that job. I'll send another letter after I have finished with that to let you know how that goes." – Frank T., IL


Problem: Efflorescence, Lime Product Used: Efflorescence Cleaner, RadonSeal Plus Sealer

"After removing the original wood paneling (36 years old) from my basement walls, I found lots of thick efflorescence and lime build up over the years. After scrapping the the loose efflorescence, I sprayed the walls with the Efflorescence Cleaner and then applied coats of  Radonseal Plus. The drywall contractor was very impressed with the before and after results. The basement walls feel and look dry." – Gregory R., CT


Problem: Efflorescence on Cinder Blocks Product Used: RadonSeal Plus Concrete Sealer

"My cinder block wall was seeping water, so I sealed it with Drylock. But after several months, efflorescence pushed it out and it blistered and peeled. I cleaned the concrete and painted it again two times, but it always peeled and leaked again. Then, I tried your RadonSeal. It pushed out rivers of efflorescence from the concrete and it is now bone-dry. Thanks" – Brian D., NC


Problem: Dirty Floor, Grime, Paint Product Used: Novion Univeral Concrete Cleaner

"Your Universal Concrete Cleaner is amazing! It has quickly cleaned my old and dirty basement floor including my grimy shop area. Although I used a 5:1 dilution, it has even removed floor paint which I planned to strip later on. And best of all, it is not toxic!" – Glenn H., MA


Problem: Old Brick Floor, Dirty Pavers and Mortar Product Used: Novion Univeral Concrete Cleaner

"Just finished scrubbing my large, family room brick floor with your Novion Universal Concrete Cleaner. I usually do this once or twice a year. The bricks are unsealed, cinnamon pavers. The floor is 32 years old. I tried a lot of different products for cleaning bricks. Yours is the best by far. The floor looks like it is brand new again. Both bricks and mortar are absolutely clean. There were no deposits left on top of the bricks as had happened with other products I've tried. Thanks very much for an excellent product." – Don G., PA


Problem: Asphalt-Based Mastic on Basement Floor Product Used: Lightning Strip

"The paint stripper works great! I've been removing asphalt-based mastic from my 48 year old basement floor in preparation to put down ceramic tile. I had tried a different brand mastic remover for the job however the product and all the cleanup is solvent-based, which doesn't make it the easiest, safest or best thing to use indoors, and the mastic wants to soak into the concrete, not exactly what I trying to achieve. I even rented a electric rotary floor scraper to try to remove the mastic. Although it scraped some of it off, I still had a fairly significant amount left to remove. The Lightning Strip is definitely the best product I've found for the job. The mastic just melts with a little scrubbing, and the water cleanup is a real plus since it can be done with a mop and bucket, leaving the concrete relatively clean." – John Z., MD


Problem: Paint Stripes on Floor Product Used: Lightning Strip

"Cheryl, Lightning Strip works great! I am removing paint stripes on my shop floors and have tried over 8 other products and they didn't work. Some I left on for 3 days, still didn't work. Within 5 minutes your product started to work with 1 coat." – Bruce W., MI


Problem: Carpet Adhesive on Office Floors Product Used: Lightning Strip

"We are a commercial general contractor and had a project that required the carpet adhesive to be removed from the existing concrete floor. This area was previously a bank of offices approximately 2500 SF that was now to be a cleaned sealed concrete floor. We tried sanding and grinding the adhesive away, but this method did not work well. We were concerned about any solvents because of the odor involved and the safety problems associated. We tried the "Lightning Stripper" and it quickly and easily removed the old carpet adhesive completely from the concrete floor. The building was partially occupied with office staff during this process and they were not bothered by the odor. This was the perfect solution for our situation. I would recommend this product for commercial carpet adhesive removal." – R.H., Expedia Construction, IL   


Problem: Paint on Basement Floor and Walls Product Used: Lightning Strip

"I applied the lightning strip to my basement floor last night and I was so happy to be able to peel large sheets of paint off easily. Tonight I'm going to spray it on the walls and I should be able to apply Radon Seal this weekend! Works great. The hardest part was get the cap off the Lightning Strip. Thank you for the excellent product!" – Meigo K., NY


Problem: Paint on Concrete Floor Product Used: Lightning Strip

"I wanted to tell you that you really have a great website, and I've already recommended it to 2 other people. You really did a great job explaining your products, and the Lightning Strip product you recommend also works really well. It actually does remove every bit of paint out of the pores of a concrete floor, which other products I've tried don't come close to accomplishing." – Carolyn S., KS
