Frequently Asked Questions (FAQ) about wood stain, wood paint, wood dye, polyurethane, wood floor coating, parquet coating, and wooden furniture.
FAQ
1. Can wood dye be used on floors?
– Wood dye should not be used on floors as it is designed for vertical applications only and does not have the durability to withstand foot traffic. It is recommended to use products specifically for wood flooring, such as Beger SuperDeck or Beger Polyurethane 1K Supreme.
2. Why does the floor feel sticky when using wood dye?
– The film of wood dye has elastic properties to accommodate the expansion and contraction of wood, which can make the floor feel sticky underfoot. You can read how to resolve the issue of sticky wood dye here.
3. Can polyurethane (Uniten) be applied on rubber tiles?
– No, it cannot be applied. Rubber tiles have high flexibility, but once Uniten dries, the paint film becomes hard, which may cause the coating to crack. Additionally, adhesion may not be good because the surface of rubber tiles is not porous like wood, leading to potential peeling during use.
4. What causes haze on surfaces coated with polyurethane film?
– Haze on Uniten film can occur for several reasons, such as using it in humid conditions (rainy season). This is often seen with 1K polyurethane, as high humidity can cause the paint to dry abnormally, with the top layer drying before the bottom layer, preventing the thinner from evaporating normally.
To resolve this issue, it is recommended to sand the hazy layer down to the film layer, clean the dust from the surface, and then reapply polyurethane over it, or opt for 2K polyurethane instead, which dries faster and does not affect the drying of the polyurethane film. You can use Uniten 2K over Uniten 1K.
– Another reason for haze is applying Uniten outdoors in direct sunlight or in a house where the floor is exposed to strong sunlight every day. The initial symptom when using Uniten outdoors is the formation of white haze on the Uniten film, and it may start to crack and peel due to the high expansion and contraction of outdoor wood. However, Uniten is a hard coating that cannot expand and contract with the wood. Therefore, for outdoor wood painting, it is advisable to use products designed for better flexibility, such as Beger SuperDeck or Beger Polyurethane Supreme Outdoor, which have a film texture similar to that of Uniten.
5. Is thinner required for wood painting?
– Generally, when painting wood, whether using wood dye or polyurethane, thinner must be mixed each time before use. However, there are now formulations that can be used without the need for thinner, such as Beger WoodStain Supreme or Beger Polyurethane Supreme Outdoor. In cases where the work area is quite large and in extremely hot outdoor conditions, it is recommended to mix thinner to facilitate application. For wood dye, it is recommended to use it with Beger Thinner M-1199 at a ratio of 15%-20%.
