I just asked this question at a local paint store and tried it at home. You put some rubbing alcohol on a cotton ball and rub it on the painted surface (you might want to do this in an inconspicuous place since it may leave a mark on your wall). If some of the paint comes off it is probably latex (water-based) paint. If it does not it is probably oil-based.
Wash a small area with a solution of houshold detergent and warm water. Rinse well and dry it, then soak a soft rag in alcohol and rub it back and forth over the area. If paint comes off, it's latex paint and you can use another coat of latex paint. If the paint doesn't come off, it's oil-based, an oil-based primer is a must
To soften face paint, you can add a few drops of water or a facial moisturizer to the paint and mix it thoroughly until you achieve the desired consistency. Alternatively, warming the paint slightly in your hands or using a hairdryer on a low setting can also help. Always test the softness on a small area of skin to ensure it applies smoothly and comfortably.
To make a homemade paint stripper for wood, mix equal parts of baking soda and water to create a paste. Apply the paste to the painted surface and cover it with aluminum foil to retain moisture. Heat the area with a heat gun or in boiling water, and then scrape off the paint once it softens. Always test a small area first and use proper safety precautions.
As a vehicle refinishing industry professional I have had the opportunity to test all the major paint brands, Dupont, Sikkens, Sherwin Williams, PPG, Diamont, RM, and in many cases I have been able to spray them side by side to compare. I can attest that all companies have their stengths and weaknesses. However the product that was the easiest to spray and yielded not only the best looking results but fastest cycle times and productivity (body shop terminology) is Sherwin Williams.
Most paint companies had stopped using lead in their paint at that time, however, never assume that paint is lead free. Use a lead paint test to determine if lead if present prior to sanding or scraping.
If you want to keep your paint color pure and cover your object and/or project with 1 or 2 coats, I wouldn't, it sounds like your trying to eliminate a step, I know they do it with stain and polyurethane but not with paint and poly. I think as long as its water-base poly & water-base paint (latex) its possible, try 1oz of paint, 1oz of poly and mix well and try it on a test piece to see if its to your liking. Good-Luck!
Water plus antacid pills are base. You can test it on litmus paper.
There is no sure fire way to test paint for lead via home based chemical compounds. The only way to test for lead is to buy a lead paint test kit.

To determine if paint is lead-based, you can use a lead test kit available at hardware stores. Follow the instructions on the kit to test a small sample of the paint. If the test shows a positive result for lead, then the paint is lead-based.

Yes, you can use a water-based primer to paint over vinyl wallpaper, but it's essential to ensure that the wallpaper is securely adhered to the wall and in good condition. Clean the surface to remove any dust or grease, and consider lightly sanding the wallpaper to improve adhesion. A water-based primer will help create a suitable base for the paint, but be aware that some moisture may cause the wallpaper to loosen if it’s not well adhered. Always conduct a patch test first to ensure compatibility.
To remove a paint stain from a tablecloth, first, identify whether the paint is water-based or oil-based. For water-based paint, gently scrape off excess paint with a spoon, then blot the stain with a cloth soaked in warm soapy water. For oil-based paint, apply a small amount of rubbing alcohol or paint thinner to a cloth and blot the stain carefully. Always test any cleaning solution on a hidden area first and launder the tablecloth according to the care instructions afterward.
No, you should not use ethanol instead of water when conducting the iodoform test. The test relies on the reaction of iodine with an alcohol in the presence of a base, typically sodium hydroxide, to form iodoform. Water is usually used in the test to help facilitate the reaction. Substituting ethanol for water can affect the outcome of the test.
To make old paint usable again, you can try stirring it well to mix the separated components. If the paint is too thick, you can add a small amount of water or paint thinner to thin it out. Make sure to test the paint on a small area before using it on a larger surface to ensure it still applies smoothly.
When an acid of low pH is combined with a base of high pH in a test tube, a neutralization reaction will occur. The acid will donate a proton (H+) to the base, forming water and a salt. The resulting solution will have a pH closer to neutral.
