Yes, as long as the polyurethane is oil-based.
Yes, both oil and water-based polyurethanes will adhere well to an item coated with acrylic paint. If it is a polyurethane paint, dull the surface prior to painting. If it is a clear. realize that that oil based polyurethane will impart an amber hue while a water based polyurethane is crystal clear and will not affect the color.
If you mean an oil based polyurethane, no, it will dry too hard and will chip off over time and normally isn't meant for exterior work. A better option would be to use a 100% acrylic clear polyurethane, paint or solid stain. They are adhesive enough to adhere to vinyl fencing or decking and will flex during freeze/thaw cycles.
PU stands for Polyurethane, a kind of plastic that's the main ingredient in the paint.
The reaction between an isocyanate prepolymer and a polyol in the presence of a blowing agent with an amine as catalyst results in the formation of polyurethane foam. Different types of polyurethane foams like flexible polyurethane foam, rigid polyurethane foam, thermoplastic polyurethane etc. are widely used for a variety of purposes.Polyurethane foams are mainly used in bedding and carpet underlay, furniture, rigid foam insulation panels, gaskets, electrical potting compounds, durable elastomeric wheels & tires etc. With an increase in its applications, the market demand for PU foams is also increasing.There are several general trading companies that are well known to be the leading polyurethane foam suppliers, PU foam scrap supplier, polyurethane trim foam supplier etc. If you are concentrated in the UAE, the Middle East or African regions, then I would like to suggest the UAE based general trading company Fortune Emirates. They are the regular PU foam scrap supplier, polyurethane trim foam supplier and polyurethane foam suppliers in UAE. You can avail quality PU materials from this polyurethane foam supplier in UAE at pocket friendly prices.
Yes, it can. I would sand it with a 220 or even 360 grit.
You can apply "oil" based polyurethane over "oil" based enamel, you can also apply "water" based polyurethane over "water" based enamel, never mix the two, there's to much of a chance for problems.
Yes, as long as the polyurethane is oil-based.
First you would want to categorize concrete sealers into A. Penetrating Sealers and B. Membrane or Topical Sealers. A. Penetrating sealer types include silicate, siliconate, siloxane, silane as well as polyester sealants and are normally water-based. Some that I mentioned chemically react with the concrete and others simply absorb and fill the concrete pores. B. Topical sealers are either water-based or solvent based e.g. the liquid carrier of the solids. The solid content of these sealers can be acrylic, urethane, polyurethane, epoxy, silicone, polyurea and polyaspartic.
Yes, both oil and water-based polyurethanes will adhere well to an item coated with acrylic paint. If it is a polyurethane paint, dull the surface prior to painting. If it is a clear. realize that that oil based polyurethane will impart an amber hue while a water based polyurethane is crystal clear and will not affect the color.
Polyurethane will give a long lasting easy to apply finish. Use a water based polyurethane ans clean up will be much easier. You should get years of wear from a good polyurethane finish.
You can apply Trojan Masonry & Concrete Sealer which is a water based polyester sealer that penetrates and hardens the concrete. As it is not a topical sealer like acrylics or silicones, you won't get hot tire pick up or a glossy, slippery finish that easily wears away.
Yes, you can.

A better option would be to use a 100% acrylic clear polyurethane, paint or solid stain. They are adhesive enough to adhere to vinyl fencing or decking and will flex during freeze/thaw cycles.

Yes, Japan dryer is compatible with polyurethane coatings. It is commonly used to accelerate the drying process of various types of coatings, including polyurethane, by speeding up the evaporation of solvents in the coating.
