Polyurethane (PU) is a material which has many advantages compared to other polymeric materials for similar applications. Now, wherever we look, we will often find polyurethane. Polyurethane can be found on various objects around us. For example , the liquid coatings and paints , elastomeric hard as the roller blade wheels , shelves made from hard , flexible foam that is soft , elastic fibers , or as intact skin , tables , chairs , cars , clothes , shoes , furniture , beds , shelves in walls , roofs , walls of the house , even a house floor is made of wood .
Applying polyurethane to wood floors is good. We prepare the room that has good ventilation, because the polyurethane fumes are not good for breathing. To protect us from the work area spills polyurethane which is very hard to remove, we need old newspapers or rags. We need to smooth the wood surface first so easily in the application of polyurethane. We can use sandpaper with different roughness sizes. For wood with a very rough surface, we use that have sandpaper coarse sand grains as well. After that, we use slightly finer sandpaper. Do not forget to clean the dust on the wood. Open cans of polyurethane and mix well using a proper mixer. If you have purchased a semi - gloss, satin or matte finish, is sure to mix it properly and that the correct amount is not too glossy finish. Stirring the mixture should not be too hard as this can cause air bubbles into a product that will damage the finish. Dip the brush into a can of polyurethane slowly so it does not drip or scattered.
Polyurethane is best applied with a brush is a bit stiff, but it can also be applied with a foam brush. Use a brush to apply the polyurethane in all parts of the wood. After the polyurethane was dry, be careful not to brush the surface. This was done in order not to decimate the sparkle of the results of the polyurethane finish. Apply a second coat of polyurethane as we did at the time of the first coating stage. Then we do applying polyurethane to wood floors well as an environmentally friendly home.
