How to Flatten Paint

1. Stir the paint thoroughly. This will ensure that the paint is evenly mixed and that there are no lumps. 

2. Add flatting agent to the paint. Flatting agents are usually sold in small bottles. The amount of flatting agent you need to add will depend on the instructions on the bottle. 

3. Stir the paint thoroughly again. This will ensure that the flatting agent is evenly mixed throughout the paint. 

4. Let the paint sit for the recommended amount of time. This will allow the flatting agent to do its work. 

5. Apply the paint as normal. The paint will now have a flat finish.

Tips for Flattening Paint

* If the paint is too thick, you may need to thin it with water before adding the flatting agent.

* You can also use a paint sprayer to apply the paint, which will help to create a more even finish.

* If you want a very flat finish, you can apply two coats of flatting agent.

* Flattening agent can also be used to reduce the sheen of glossy paints.
