Can One Use The Primer As Paint?

Use The Primer As Paint

One can use a primer as paint depending on the physical location and interaction of the surface. For instance, one should not use the primer as paint in a room which people live in as it does not form a scrubbable surface. Cleaning a wall painted with primer leaves scuff marks are likely to show since primer lacks the same binders and polymer components normal paints have.

What Is The Purpose Of Primer Paint?

 A paint primer is a product that is used under the first coat of paint. It is used on both interior and exterior surfaces. Its main purpose is to prepare surfaces for painting. The paint primer has other functions, making the wall surface smoother to ensure paint glides easily on the surface when painting. It extends the normal lifespan of paint while also adding protection to the wall surface.

 Other secondary purposes are covering dark shade walls that require a change in color of the paint. The primer conceals the initial color of the wall, preparing it for a new one. It acts as a blocker and helps the wall maintain a clean, clear and attractive look after painting.

How Long Should One Wait Between Primer And Paint?

 Time taken by the primer to dry depends on various factors such as humidity level in the environment. In areas with high humidity levels, primer takes longer to dry. When used interiorly, one should ensure the availability of air conditioning before the painting process begins. Some primers have indications on when they will dry written on their instructions. Some take an hour or two, whereas others may take up even 24 hours. 

Most oil-based primers take longer to dry and should be given at least 24 hours to ensure it has dried completely and is ready for another coat of paint. It is important to check the instructions on the primer’s time to dry for perfect and long-lasting results. If a primer coat fails to dry, the general paint of the surface will peel off after a short period.

How Many Primer Coats Should One Use?

 Normal paint can stick to an unprimed wall, although there will be risks involved such as blotchiness, cracking and peeling of the wall. The primer contains more resin and fewer pigments compared to normal paint. Therefore, it can stick more firmly on the wall, although less attractive due to low pigment. The number of primer coats depends on the wall material, the initial paint color, and the type of primer to use.

You can use one primer coat when;

Painting Another Color Over A White Wall

A single layer of high-quality water primer or oil-based primer is enough to bind an old white painted wall and create a new shade. It helps in masking stains and recent patches on the wall. Additionally, they help reduce the amount of paint needed to cover the wall fully.

Using A Tinted Primer 

Primer similar to the new paint’s shade is important when making drastic changes such as light to dark color and vice versa. Such primer brings the color of the wall close to the intended hue; hence less paint is used. If the intended color of the primer is unavailable, one can easily get the color adjusted to their desirable primer tint. With tinted primer, one can easily attain their desired color shade on the wall with a single coat of primer.

One can use two primer coats when:

Painting Unfinished Drywall Or Plaster Wall 

Drywall and plaster tend to be more porous than other walls, especially if they were not primed or painted before. Two primer coats are used in such walls since the first coat primer will be absorbed and soaked up by the drywall. The second primer coat acts as a cleaner and replenishes all the primer absorbed by the wall. 

Unfinished plaster walls should be primed with two coats of oil-based primer that acts as stain blocking. Such primer helps prevent lime stains from forming as they affect the plaster walls causing them to bleed into the paint.

Painting Unfinished Wooden Walls

Unprimed wooden walls are even more porous than normal drywall. The levels of solids available in normal paint cannot fill the pores of a wooden wall and flatten the grain. Painting a wooden surface without primer results in an uneven surface and may result in blotching and peeling.

 For this reason, two coats of oil-based primer are recommended so that the first coat can fill the pores and the other one can level up the surface, preparing it for painting. Water primer does not work well on wooden surfaces as it causes the grind to swell. It requires one to sand the surface first then apply the water primer.

Painting Over A Darker Color With A Light Hue

 Primer is very important when making transitions from dark to light hues. Failure to use primer the dark color continues to peek even when three or more paint coats are used. The best primer for dark walls is a high hide primer which conceals the previous dark color completely. Two thin layers of either white or tinted primer are used to bring the surface color close to the intended output; hence fewer paint coats will be used.

 Sometimes primer is not necessary when painting. For instance, when one is using a self-priming paint. Self-priming paint, also known as two-in-one paint and primer, contains higher solids levels than normal paints. The high level of solids makes them produce a thicker coat. However, they only work best when used on light color walls or on smooth walls, which are in good condition. They also take longer to dry up than normal primer and paint.

What Happens If One Fails To Use A Primer Before Painting?

 Painting a wall without using a primer before paints results in a lack of uniformity between the paint color and sheen. The primer provides a sealing nature to a surface that helps paint to cover it properly. Failure to use primer reduces the paint’s pigment since a lot of it is absorbed by the surface, causing high pigment levels to be soaked into the surface. It results in an unprofessional look with a light color, which is unevenly distributed. Some surfaces appear to be washed out, and the desired color is not achieved.

Primer provides the surface with glue-like bases and flat sheen, promoting adhesion between paint and the surface. The stickiness and adhesion from the primer are what makes the paint stick on the surface firmly. Applying paint without primer creates a pool of risks such as paint blotching and chipping off the painted surface. The paint also easily wears off from the surface as it is not firmly attached.

 Failure to use a primer before paint results in stains and leakage of damaged walls. Old and damaged wall surfaces may have stains from smoke stains, poor water drainage, and sometimes unpleasant pet odor. Primer conceals such stains and removes risks of them getting damaged again as it acts as a sealer and blocker from such factors.

Under What Circumstances Must One Use A Primer?

 Primer is a must in cases of uneven surfaces. When one intends to paint an uneven and porous surface, using a primer is very important. Such surfaces include drywall, wood and bricks. The reason is that paint gets into the pores of such surfaces; hence a lot of it is required. Even when a lot of paint is used, it still looks unattractive. The desired color is not achieved since most of the paints’ pigment is absorbed into the surfaces.

 Another circumstance under which primer is a must is when the surface to be painted is glossy. Paint does not stick well on glossy surfaces, which is why people sand the surface first before painting. Primer is less glossy and has an adhesion property making it stick on a gloss surface. It leaves some roughness suitable for the paint to stick firmly.

 Also, when changing a dark surface color into a lighter one. It is difficult to cover a dark color with mere paint. That is why one will need a primer which makes the process easier. White primers can cover a dark color in either one or two coats. There are also tinted primers customized to fit the desired color, whereby the primer is stained to suit different shades. Such primers will require just a single coat, and the surface will be ready for paint.

Conclusion

 One can use a primer as paint, but the satisfaction of the outcome is not as much. The reason is that primer has less pigment; hence the desired color may not be achieved. It also leaves a rough surface, creating a dull, flat, and less reflective surface on one’s walls. One should ensure that the surface to be painted with primer is not accessible by children and pets as it easily gets rub off a surface. It would be best if used on high surfaces such as ceiling boards where there is minimal contact.
