Question: Approximately how many square feet can I expect to get done with a quart? Stripping paint from concrete...
Document: Granted, I was trying to remove about 120 years of paint layered in 8-10 colors (not sure how many actual layers), but I didn't feel like multiple layers were removed "easily" while following all the instructions. It eventually all came off, but it came off unevenly. It also required enough applications to use the whole bottle on a transom window frame (probably less than 4 square feet). Overall, it was better than I was expecting, but still not great.
Easily remove multiple layers of paint, urethane, acrylic, epoxy or enamel without the back-breaking work of sanding and chiseling and without the odor of other furniture strippers! Made with 100% American-grown soybeans, SOY-Gel starts to lift the coatings in minutes.One quart gives you up to 50 square feet of coverage three times the coverage of most traditional strippers. Indoors or outdoors, you can be guaranteed a safe and easy restoration.Ideal for lead-based paint removal.
It's more expensive, but as long as you use it right it will get the job done. Many of the reviews that say that the product works better the longer you let it sit are correct. Usually we will let parts sit overnight for starters and then continue from there. We have used this product on paints manufactured anywhere from 1800's to modern paints and the product does work on them all eventually.
It clings extremely well and I was able to establish a 1/8" coating on the stock. It was 75 degrees, indoors, and I left it on for five days! In the end, there was a spot about two inches square (the same spot I would test scrape daily) that removed some finish. The rest of the stock was untouched by this stripper. The bottle says it will do about 50 square feet.
I bought this product over a year ago and finally got around to stripping one of the many old interior doors in our 70 yr old house. SOY-Gel itself doesn't have much odor to it, but I noticed as it worked on all the different layers, the odor changed according to the paint type (which ranged from latex, oil, lead-based, and poly).
Does not contain methylene chloride. Cleans up easily with water. Safe to use on wood, brick, stone, metal, plaster, concrete, and many other surfaces. Do not use on plastic, PVC, rubber or dry wall. May be used indoors or outdoors
This stripper is the least noxious of any that I have tried so far, so I give it much praise on that front. It does take off all the types of paint that it indicates, but in my experience, it requires multiple applications, particularly when there is latex paint on top of older types of paint. I'm stripping doors that have between 3 and 7 layers of paint. It is taking up to 3 applications to remove all the paint, even when I leave it on for many hours.
I bought this as an alternative to sanding off lead based paint. I thought this would do the trick but was a waste of time. First you have to paint this gel on the whole surface and then you are actually supposed to wrap everything in plastic that you just applied the gel to - what a pain! After all this effort and 24 hours of waiting, it made some nice bubbles, but that's it. I guess you have to use poisonous chemicals to get the job done.
I apply the SOY-Gel real thick and forget about it for about 24 hours. No matter how many layers of paint there are, they peel or fall right off. I use a small wire brush to get into the corners and wipe down with lots of damp warm cloths. All thats left to do is lightly sand and restain. I can use this product in the house without the harmful affects of vapors or fumes and no matter what the weather is outside.
We used the whole quart stripping one tabletop. The stuff has little smell, which is good. Other than that it works about the same as the stinkier kind.
