You cannot do so. Even if you paint with enamel first, then with latex, the two will not attach to each other. You must first remove all of the enamel before applying the latex.
Here are some things to consider when mixing paints:
Enamel is used for its high shine and protection from corrosion while latex is used because it can be thinned with water for a drippy look. They work well together because they have different styles of painting that suit each other's limitations. For example, if you want to cover a large area but don't have much patience, enamel is your go-to material because it's easy to apply in big swaths. But if you have any doubts about your painting skills or lack thereof, stick with a product that requires professional help.
As long as you are combining only equal amounts of the two products, there should be no problems mixing them together. However, if you are using enamel in a larger amount than latex, you may need to add more water during application to make sure the paint doesn't become too thick.
Non-latex paint cannot be mixed with latex paint.
Using Latex, paint over the varnish. Contrary to common perception, latex paint may be applied over enamel. However, in order to avoid future peeling paint, you must first do the necessary preparation work. The best way to prepare for painting over enamel is to strip and refinish the piece with a new coat of varnish.
You should also plan ahead to make sure there are no problems before you start painting. For example, if you notice any cracks or other defects when you are done preparing the surface, now is the time to fix them. If they aren't visible yet, then they won't come out until after the paint has been on the wall for a while.
Finally, remember that while latex paints are easy to work with, they still contain oil and can cause your varnish to peel off in places. If you want the final product to look perfect, then you should really let a professional handle it. Otherwise, you might get lucky and it will just look like another room in your house.
The best thing to do is check with your local home improvement store or with people who have done this type of job before. They should be able to give you advice about what products you need and how to go about doing this project properly.
Unless both are latex-based, it normally does not mix. Enamel is a kind of oil-based paint. If the cleaning instructions on the enamel state that turpentine or mineral spirits (paint thinner) are required to clean brushes, they will not combine. There are latex paints with an enamel finish. These include Zinsser Golden Acrylic Latex Paint.
In general, any kind of paint can be mixed with any other kind. The only thing you don't want to do is mix latex with oil-based paints because they will go bad together. You should also avoid mixing different brands of latex because each brand has its own unique formula for additives such as driers, thickeners, and softeners. If you mix these ingredients, the results may not be what you expect or even like.
As long as you use the same type of paint brush for both oils and latex, there is no problem combining them. However, if you use different types of paint brushes for oils and latex, you should try not to get any residue from one type of paint onto your next type of paint tool. For example, if you use a flat brush for oils and a round one for latex, make sure to wash both tools after using them with different kinds of paint.
You should also wash all tools that have been in contact with paint before washing them. This includes pans, buckets, or containers used for storing or blending materials.
Yes, you may mix interior and exterior paints together, but the paints must be of the same type. Yes, they both contain the same pigment, have the same shine, and are, of course, paint. However, one side effect of mixing different types of paint is that you will get a color that is neither interior nor exterior; it will appear grayish. You might want to consider only mixing interior paints for best results.
The best way to mix paint is in equal parts. This means if there are 20 ounces of each color, then you should be using 40 ounces of each color total. Use a mixture of colors instead of just one pure color. For example, if you wanted to use a light blue color for your ceiling and a dark blue color for your walls, then mix those two colors together to create one new color. The resulting color will be somewhat light blue and darker than just one of the colors used alone.
You can also mix paint by volume rather than by weight. So, if you have 12 cups of each color, then you should use 24 cups total. Just make sure that you include some white in all your mixes so that you do not end up with a color that is too dark or too light.
Now, this isn't to say that you cannot get creative with your painting projects.
Is it possible to paint over oil-based paint? Latex paint (and even other oil-based paint) can be properly put over earlier oil-based paint if the surface is fully dried and there is nothing in the coating that prohibits another layer of paint from being placed. The new paint will adhere to the old because they are both oil-based.
As long as you are careful not to get any water on the new paint when you apply it, it should be fine. Make sure to use a primer first if you want the paint to look its best before applying a second coat.
Does your local hardware store sell brushes for painting house frames? Yes, they sell brush sets for painting doors and windows. These sets usually include brushes for brushing off dust prior to painting and brushes with different shapes for painting details like molding and casings.
Painting door frames is different than painting house frames because window frames have very specific dimensions while door frames can be of various sizes. So instead of using one big brush, you need several smaller ones for this job. Also, because door frames do not have any grooves or curves to trap dirt, it is not necessary to clean them before painting them. However, if you see any dust on the frame, you can use a vacuum to remove it before starting to paint.
