What are polyurethane finishes?
Many amateur and professional wooden workers consider polyurethane finishes to be the simplest application and the most durable of all types of wood. There are two different types of polyurethane surfaces, based on water and solvent. Both leave a strong protective coat on the wood and each has advantages and disadvantages.
polyurethane surface treatment based on solvents are older and established form of surface. The solvent -based polyurethane surface is subject to a chemical reaction during the curing process. The chemical reaction leads to the polymers strongly connects together. Once this process has occurred, the goal cannot be decomposed and dissolved in mineral ghosts.
The solvent -based polyurethane has disadvantages. As you can imagine, the vapors you encounter while working on wood with this solvent -based surface are stunning. It is important to work in a well -ventilated area.
Another disadvantage of polyurethane based on the basis of solvent that they can light wood lightly on yellow. ItIt will not usually be evident in darker colored wood, but on extremely light wood it can cause a noticeable color change. The end will continue to darken over time.
Polyurethane surface treatment based on water also have their disadvantages and advantages. The chemical reaction that causes a solvent -based polyurethane binding is not present in water -based polyurethane. This means that water finish is not so durable.
, however, water -based polyurethane is dried quickly and easy to clean because it is easy to clean. Even if you should always work in a well -ventilated area, water -based polyurethane vapors are not nearly as strong as fumes from the solvent -based surface treatment.
Polyurethane surface treatment based on water and solvents can provide a beautiful and glossy finish. Regardless of the type of polyuretuhane you choose, the process is similar. Most importantThe step towards creating a glossy surface on your wood is to apply several thin layers of polyurethane to the wood.
If you want to apply a polyurethane surface, start with grinding wood. Plant or wipe the wood to remove all dust and fiber from the piece. Apply a thin coat of polyurethane and let it cure. Water -based polyurethane usually takes approximately one hour of drying, although this time the humidity increases. The solvent polyurethane needs about four hours to dry.
Repeat grinding, cleaning and application at least three times. For the final application of polyurethane, grind a piece with wet and dry paper. After the final coating of the polyurethane dried up, the wood with polishing pounds. Whether your polyurethane surface treatment is based on water or solvents, this process will leave you with a high gloss.
