Many people experience difficulties in choosing the right product to use. Some encounter the wrong type of product, whether it is oil or water-based variety. Both Oil-based and water-based coating have the same level of durability

If you want to have a transparent coating surface for your woodcrafts, it is better to use the water-based formula. It gives a clear and glossy surface.

Impacts that affect woodcrafts when you use the wrong product

It is essential to check the product first before the purchase. Have you ever tried using a water-based paint on an oil-based coating? You would not want to have a hard time redoing your work. You would not want to waste your money to buy things to redo the work. Some impacts that a wrong chosen product may result are:

  • There are instances that the paint was not applied consistently. This results from having bubbles on the surface. When this situation occurs, use the paint with directions to avoid the uneven result.
  • Another thing is about the appropriate tools to use in applying the paints. There are several tools in painting. Examples of that are brushes, rollers, or any DIY tools, such as disposable foam brushes.
  • The first step to do when working is preparing the tools or the equipment that you will use. Here, a painter or a worker should know the right tool to use before starting. This is necessary to avoid mistakes that may cause redoing the work.
