Sometimes, when the paint is watery, it means that it has gone bad and should be thrown out. Also, there are times when paint thinner or thickener should be used.
In this manner, how do you fix watery paint?
Add the cornstarch mixture to the paint. Slowly add the cornstarch mixture to the tempera paint stirring occasionally. Use a spoon to add the cornstarch mixture or slowly pour it into the paint. Add the cornstarch mixture until the paint reaches the thickness you desire.
Subsequently, question is, how do you make watery paint thicker?
How to Thicken Latex Paint
- Transfer watery latex paint into a bucket large enough to hold the amount of paint to be thickened, plus at least an extra 1/4 of the bucket for added thickener and stirring.
- Slowly add the cellosize hydroxyethyl cellulose to the paint by pouring it in.
- Stir the paint as you add the thickener.
Paint primer is typically of a thinner consistency than finish paint. Since the primer is thinner than finish paint, a lower-nap roller will provide more even coverage. As with paint, primer should not be over-saturated in the roller sleeve.
