There are two types of paints. One is oil-based paint, and the other is water-based paints. Oil-based paints are known as Alkyd paint, and water-based paints are called Latex paint. Removing wet/hardened oil or latex paints is a tough task to do. But, cleaning them from the spray equipment is crucial and a necessary thing.

Why is it important to clean the sprayer?

When we talk about Latex paints, they are water-based paint which uses water as their mediums. They are made of new synthetic resins and have a thinner consistency. Any spray guns can use latex paints as they are wet. But, if you compare both the paints, you will find that the Oil-based paints are thinner than the latex paints and also, they do not clog the spray gun nozzle where latex paints are quite thick and may clog the nozzle. So, if we don’t clean the sprayer properly, it might not work the way it is designed to!

How to Unclog a Paint Sprayer?

There are various ways to remove the clog. Amongst them, the easiest way is to use some brush & sprayer cleaners. For brushes, pour the material in a container and soak the brushes in it. Allow them to sit for an hour and then take them out to rinse it with the clean water. Keep one thing in mind that if the paint is dry on the brushes, then such painted bristles may need a more extended period to be cleaned. But don’t soak the wet brushes for more than 60 minutes. Sometimes, the synthetic bristles may swell.

For sprayers, you have to pour the cleaner into the spray cup or container and spray continuously, without leaving it. You will soon realize that all the paint has come out and your paint gun is clean now. If you want to clean it thoroughly or any heavy duty cleaning, it is advisable to remove the parts of the sprayers and soak it for some time.  Then rinse it with regular water and clean all the parts with the cleaning brush.
