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.
Industrial casters are very strong polyurethane wheels that can hold hold up alot of weight! Usually the more costly they are the more weight they hold. They should roll very smoothly and not rough!
No, it is not recommended to apply water-based polyurethane over a surface that has been previously coated with oil-based polyurethane. The two types of polyurethane do not adhere well to each other, which can lead to issues with the finish. It is best to stick with the same type of polyurethane for recoating.
They'll hold up well, and can be easily sewn if required.
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.
No, it is not recommended to apply water-based polyurethane over a surface that has been previously coated with oil-based polyurethane. The two types of polyurethane do not adhere well to each other, which can lead to issues with the finish. It is best to sand down the surface and remove the oil-based polyurethane before applying the water-based polyurethane.
How you can best clean up spilled polyurethane will depend on where it is spilled. If it is spilled on a laminate floor, rags dampened in mineral spirits will work well. If the spill is on concrete, paint thinner will clean it up.
To effectively apply polyurethane in cold weather conditions, it is important to warm up the polyurethane before use to improve its flow and application. Additionally, working in a well-heated and ventilated area can help the polyurethane dry properly. It is also recommended to use a slower-drying formula specifically designed for cold weather conditions to ensure a smooth and even finish.
Yes, epoxy generally adheres well to polyurethane surfaces due to their similar chemical compositions and compatibility.
Yes, it works well with that.
To clean up oil-based polyurethane effectively, use mineral spirits or paint thinner to remove any spills or drips. Wipe the affected area with a clean cloth soaked in the solvent until the polyurethane is removed. Be sure to work in a well-ventilated area and wear gloves to protect your skin. Dispose of the solvent properly according to local regulations.
No
I would use an exterior polyurethane. It is going to hold up better and be more flexible than a varnish. Polyurethane has taken over the varnish market--it's hard to find any other kind. There is a "spar polyurethane," which is what you should use on the item in question.
