Thinning Chalk Paint for Spraying

Chalk paint is too thick to spray directly out of the can.  Most paints are.  You even have to water down and thin latex paint for spraying.  That's because the nozzle on your paint sprayer is made to combine air and paint and spray it out in a fan pattern.  Paint needs to be thin to spray through your nozzle or tip.  

If your chalk paint is too thick, it will either come out of your nozzle in clumps onto your projects or clog the nozzle all together.  This can result in ruining your paint sprayer.  Even Annie Slaon Chalk Paint needs to be thinned with water for it to be sprayed and to get those Pro results your working hard for.

How Much Water to Thin Chalk Paint?

Thinning chalk paint is just like thinning other types of latex paint.  The first step is to read the manufacturers instructions on the can.  They may have directions as to how much water to use to thin their chalk paint for the best results.  The worst situation is when a paint can't be thinned, but that is so rare, you shouldn't worry about it.

If there aren't any thinning instructions here are our basic instructions for thinning paint with water until you get the best consistency with your paint for spraying.

Chalk Paint Too Thick: Here's How to Thin it with Water

#1. Pour all of your paint into the bucket that you intend to use for that day. 

#2. Add ½ cup of water to the paint for every gallon of paint that was placed in the bucket. 

#3. Mix the paint and water thoroughly with a clean stirring stick. 

#4. Check the consistency of your paint by running it through the funnel. 

If the thinned latex paint is able to flow freely through the funnel, then you have the correct consistency.  

Sometimes, you will need to add more water.  If that's the case, add 1/8 of a cup at a time and mix, until your chalk paint flows through your funnel freely.

Once you add some water to chalk paint, the consistency or color might change.  Also, it will take more coats to get the same amount of coverage that you would if you used a brush or roller.

For you hands on folks, here is a handy video showing thinning chalk paint for a sprayer.  If your looking for the viscocity cup she uses in the video, here is a link.  

Oops, My Chalk Paint is Too Thin Now!

Never fear.  if you over-thinned your chalk paint, go ahead and add back some paint, a 1/2 cup at a time and mix thoroughly, until it's thickened back up, just enough for spraying.

Conclusion

When you chalk paint is too thick, you will have to thin it if you plan on painting your project with a paint sprayer.  Just add a bit of water and stir to get it to the right consistency following our directions above.  Happy Painting!
