When applying a wood finish, especially for interior wood floors, it requires a considerable amount of time as it needs to be applied in 3-4 coats, with each coat taking about 1.5-2 hours to dry.
Reasons for the finish not drying
- Incorrect mixing of colors Typically, a two-component polyurethane color (2K) in one application set consists of two parts, referred to as Part A and Part B. When using it, they must be mixed in a 1:1 ratio. If this ratio is incorrect, it may cause the color to dry slower than it should.
- Incorrect mixing of thinner or using the wrong type When using Uni-Ten 2K, thinner must be mixed in a ratio of 1:1:1 (Part A : Part B : thinner). It should not be mixed too much or too little. Furthermore, the thinner should be selected according to the specific use only.
- Insufficient drying time between coats As mentioned, the drying time for re-coating with this type of paint is 1.5-2 hours. If we apply the next coat too soon, it will prevent the previous layer from drying, which will affect the final coat as well, causing it not to dry.
Solutions to the problem
- Wipe off the uncured paint film with a cloth soaked in Thinner M-77 until completely removed. Then leave it to dry, and use 320-grit sandpaper to sand it down and clean it.
- In case you want a glossy paint film (510)
Mix Beger B-5000 two-component polyurethane glossy type (510) in a ratio of Part A to Part B to Thinner M-50 in a 1:1:1 ratio, applying 3-4 coats, allowing each coat to dry for 1-2 hours. - In case you want a matte paint film (511) or semi-gloss (513)
Apply Beger B-5000 two-component polyurethane glossy type (510) in 2 coats, allowing each coat to dry for 1-2 hours, then apply Beger B-5000 two-component polyurethane matte (511) or semi-gloss (513) by mixing Part A to Part B to Thinner M-59 in a 1:1:2 ratio for another 2 coats, allowing each coat to dry for 1-2 hours.
