Polyurethane for floors, in short a PU floor, is a lightly elastic plastic floor that can be applied virtually over any surface. Due to the seamless character of this floor, it is easy to maintain and is very suitable for use in modern interiors with a sleek design. Polyurethane is a liquid plastic polymer that has both hard and flexible properties after dehydration. It is widely use in paints and coatings. Think for example of car paint where scratch resistance, gloss and flexibility are important. Polyurethane was developed in the 1960s and has for a long time been use mainly in industrial cast floors. Nowadays you see PU floors more and more in public buildings, offices and modern interiors. The characteristic feature of a PU cast floor is that it is apply layer-wise. Each layer has its specific properties.
The first layer is a primer that ensures that the floor can adhere optimally to the substrate. The subsequent layers provide elasticity, firmness and the ultimate appearance of the floor. A total of four to five layers are apply, which must dry in between. In principle, a PU floor is available in all possible RAL and NCS colors. Polyurethane for floors can be finishes in both matt and high gloss. There are a number of color effects possible but the choice here is not as extensive as is the case with Epoxy floors. Below you see a PU cast floor with two-color effect. For the best effect, you can best paint or stain the walls to the ground. This way the cast floor can seamlessly connect to the wall and you get a nice tight effect. You can omit a plinth in this way.
A polyurethane floor is best clean with a dust swiffer, a soft broom or a vacuum cleaner with a soft mouth (parquet brush). Wet cleaning can be done with a non-aggressive all-purpose cleaner or with a special PU cleaning agent. Do not use too much soap as this can result in an undesirable greasy soap layer on the floor. A polyurethane floor is scratch sensitive. With a top layer of good quality, however, you can avoid most scratches. The application of the floor takes four to five days. Depending on the polymer used, there may be some odor nuisance. The price of a polyurethane for floors depends on a lot of factors. Not only the total surface area will be of importance, also the degree of difficulty, substrate, desire effect and the number of layers require.
