White emulsion paint can be used as a primer for interior wood and plaster surfaces. Dilute the emulsion 3:1 with tap water and apply an even coat to the prepared surface. Allow emulsion to dry for at least 2 hours before coating; Use only water-based paints on a dispersed base; latex and oil paints are not suitable and tend to chip.
The ideal primer acts as a perfectly smooth and even coat that forms a strong bond between a surface and the layers of paint applied over it.
The correct primer is crucial when painting large areas, especially plastered walls and ceilings. Any irregularities in the primer can feel like a sore thumb even after painting over it in multiple coats.
An emulsion is a type of water-based paint; It is commonly used to paint walls and ceilings.
Emulsions contain added chemicals that increase their stability and durability. These chemicals are usually a mixture of synthetic resins, color pigments, biocides, and other chemical additives.
Emulsion paints are not intended as a primer; However, they can form a durable, soft undercoat.someinterior surfaces.
Read on to find out what materials are suitable for an emulsion base. We have also outlined the steps you need to take to properly dilute an emulsion base.

What is the difference between emulsion and primer?
The termEmulsionrefers to a specific type of water-based paint.
A primer refers to any smooth coat applied to a surface that is to be painted or varnished with additional coats. The primary function of a primer is to provide a paintable surface for other paint or finishing applications.
Most of the dispersions available at hardware, grocery, and paint stores are labeled for interior use only and are rarely marketed as a primer.
However, emulsions can be used as a safe and effective primer on some interior surfaces. The following table provides guidance on when an emulsion primer may be appropriate.
Emulsions that contain synthetic resins (acrylic, vinyl, acetate or a mixture of these substances) last longer than those that do not. These chemical additives help prevent scratches and resist peeling.
What emulsion paint is the best?
Using a high quality premium emulsion results in a noticeably better finish. These products can be relatively expensive, but spending the extra money and investing in the best brands is worth it.
Poor quality emulsions have a thicker, glue-like consistency. It is not impossible to paint a smooth, even finish with these emulsions, but it will require more time and effort.
They can also contain less beneficial chemical additives, causing the coatings to degrade faster.
Cheaper emulsions may also contain lessBiozid. A biocide is added to almost all paints - these are special chemicals that prevent mold from forming in the paint can and on painted walls.
Always follow the manufacturer's instructions when using emulsions. Pay close attention to the drying time required between coats. This can vary from 30 minutes to many hours; Drying time is longer in cold and humid environments.
Can emulsion paint be used as a primer?
Absolutely! Emulsions can be used as a primer, but additional steps are required.
A primer prevents wood, plaster, and other porous surfaces from absorbing paint or other coatings. The primer acts as a protective layer between the material and any top coat, e.g. B. Matte, gloss or satin colors.
The coats are sometimes calledDecklackeofinishing coats.
Primers help bond paint to plaster that is too wet, soft, or dusty. They also act as a physical barrier between the plaster and the paint; Plaster is alkaline and can chemically react with some types of paint, resulting in unsightly and unstable walls and ceilings.
All materials except metal are porous; This means that they trap small amounts of moisture within their internal structure.
As the temperature rises, such as in the summer months or in a heated room, this moisture will slowly be absorbed from the material into the surrounding atmosphere, breaking down paint layers in the process.
How much water do you mix with the primer?
To use the emulsion as a primer, increase the water content of your emulsion by diluting it with tap water. This is known in the trade as adding aNebelmantel.
dilute your emulsionPaint by adding one part water to three parts paint, or until thin enough to barely stick to a brush. The goal is to apply a very thin coat of primer to the surface to prepare it for painting.
When can I not use the emulsion as a base?
If you plan to paint a wall or ceiling with oil, latex, or enamel paints, do not use an emulsion primer. As the old saying goes, oil and water don't mix and this advice should be kept in mind when painting.
Use only water based paints such as B. Acrylic, over emulsion primer. Oil-based paints cannot physically bond with water-based emulsions.
Ignoring this vital information results in a gummy, peeling mess that will only get worse as the layers of paint continue to dry!

Can the emulsion be used as a primer on wood?
Emulsions can be used to prime wooden surfaces.ButThey can only be used on interior surfaces.
Most emulsion paints are not durable enough to withstand outdoor applications;not weather resistantand does not withstand extreme temperature fluctuations.
Satin wood paint is almost always a more durable option for priming and painting wood. However, these items are often more expensive than emulsions, which can work just as well for a fraction of the cost.
Wooden floors should not be dispersion painted, they are simply too weak.
Baseboards, railings, walls, ceilings, furniture, and other infrequently touched wooden surfacesSonSuitable for dispersion primer and top coat.
Wood that has been coated with an emulsion primer has lower durability than plaster and sheetrock.
To increase the hold of the emulsion, sand the surface of the wood well before applying the primer. A coat of varnish or a thicker emulsion is essential if you want your varnished wood to last.
Is a primer necessary to paint walls?
All porous surfaces must be primed before painting.
Without a primer, even traces of moisture will be pushed through painted surfaces as they try to escape the material.
Eventually this will cause the coated surface to crack, peel or blister. This costly and time-consuming bug is easily fixed by selectingthe right foundationbefore applying more coats of paint.
There is a wide range of specialized primer colors for different materials, but a standard emulsion can also be used. White emulsions work best because colored emulsions contain pigments that can prevent the emulsion from adhering properly to a surface.
Can I use an emulsion foundation on...?
Below is a list of different materials you may want to apply your emulsion to and whether or not you can do so.
| Material | Low quality emulsion primer. | High quality emulsion primer. |
|---|---|---|
| wood (inside) | Maybe (poor durability) | Yes (but satin wood color is better) |
| wood (outside) | NO | NO |
| fresh plaster (interior) | Possibly (poor durability, after 4 weeks of drying) | Yes (after 4 weeks of drying) |
| Old plaster (interior) | NO | Yes (after grinding and sealing) |
| brick (inside) | NO | Yes (only on porous brick, after priming) |
| concrete (inside) | NO | Y |
