yes
Yes, it can. I would sand it with a 220 or even 360 grit.
No, in fact the wax can ruin the polyurethane finish. Clean the floor with a good wood floor cleaner. Do not mop with water.
You can remove polyurethane from fabric by scraping off the excess using a rubber scraper. Use the blade of a sharp knife to further remove the top layer of polyurethane. Then, apply acetone to the stain and allow it to work for 10 minutes before rinsing the fabric with water. If the fabric is white, soak it in bleach and water for 30 minutes, then wash as usual.
Try using oxalic acid, also called wood bleach, on the water damaged area before attempting to stain the wood. If that removes the stain, sand the surface, use a wood conditioner or a clear stain as a first coat, then apply the colored stain. Once that's dry, apply a clear polyurethane for interior use, or a spar varnish for exterior use.
no you cant it will stain your carpet
Empty battery, water, stain, dust or somebody threw it at the floor.
Best way to do that is cleaning it with vacuum cleaner then if it has stain use a rag and a little water to clean the stain. Just remember don't immerse it in water.
any liquid will stain concrete, even water. If you have A "water mark" from any liquid, You can use floor dry or kitty litter and put it on then rub it in with your feel, This takes A lot of foot work but the result will be worth it if you are that woried about the stain.
CPI spray is made of Polyurethane Foam. Polyurethane Foam is made by adding water to polyurethane plastics.
in non wet environments it will hold up for years as long as its not on a floor. never use water based poly in a wet envitronment.
Chocolate is water soluble, so it will just require water and scrubbing. If it's a harder stain, scrub more vigorously
I am doing that right now. It says on the can that it can be applied over an oil based stain...but the stain may continue to "amber" under the coating. I decided to go with the polyacrylic because a friend told me that polyurethane yellows over time. I don't know if that is true...but that is what I decided to do. So far, the acrylic is going over and drying over the oil based stain without any problems.
