without comments

The aim of any paint work is to leave the painted surface as clean and attractive as possible. Most professional painters have gained a lot of experience and skills when it comes to mixing the paint so as to come up with a high quality paint work. In the market you will find a number of paint types that have been introduced by various manufactures but the original oil-based and water-based paints can still be found. The companies that come up with the paints technology try to remove the volatile organic compounds (also known as VOCs) as these compounds that are known to have adverse health risks. As the water-based paints have low VOCs, they are more preferred than the oil-based paint which most manufactures are trying to eradicated due to their high levels of VOCs.

The reason why the oil-based paints are still in use is because some of the experts argue that the oil-based paint have a better finish than the water-based paint. The oil paints also beats the water paints in the ease of use category as the oil paint have a leveling effect that makes the finish more smooth than that of the water paints. Oil based paints also have the shiny finish that is preferred for most polished wood finish and the pain work is very durable.

The water based paints are known to have a shorter drying time and all you have to do is use plain water if you want to clean your tools. The water paint doesnt yellow due to UV light exposure. The disadvantage of the water paint is that you cannot use it to have a high polish as in the case of the oil based. In case you want the paint work to last longer, you should consider using double layers. The water based paint should be an undercoat while you can apply the oil-based paint for the over coat for a high shiny finish.
