When plastering, you may be wondering what primer do I need. If you’re not sure what type of primer you need, this article will help you understand the different types of primers available and which one you should use for your project.
Here, we’ll go over the different types, including Water-based primer, Latex primer, and Wood primer. Here’s an example of each type, along with how to use them.
If you’re painting a plaster wall, you should use an oil-based primer. Oil paint can be messy and can bubble up when you use hot water, so you’ll want to prime the surface before painting. A stain-blocking primer is an excellent choice for plaster walls because it prevents lime stains from bleeding through. It also makes the paint stick to the wall better, which prevents decades of grime and potential stains from affecting the color.
Oil-based primers are usually not very easy to clean, but if spills occur, use mineral spirits to remove the traces. Before painting, make sure that the surface is clean of flaking paint, and stir the primer thoroughly before applying it. You should use multiple thin layers instead of a thick one, since the primer can take a few hours to dry. Then, paint over the surface. Make sure you allow it to dry thoroughly before applying any new paint.
Oil-based primers are the industry standard for decades, and they are ideal for plaster walls and are widely applicable to a wide range of surfaces, including wood and metal. They are also good stain-killers and block stains. The consistency of oil-based primers will vary, so check the product’s label carefully. You’ll find the one that’s right for your project. Just be sure to follow manufacturer directions.
Primers are an essential step before painting. It seals porous surfaces and helps paint adhere to the surface effectively. It also prevents stains and other contaminants from seeping through. It also evens out walls after repairs. And finally, it’s an essential part of painting a wall. So, before starting your painting project, remember to test the plaster thoroughly with an oil-based primer. You’ll be glad you did.
If you’re planning to install a new paint system on your plaster walls, you will need to apply a good quality water-based primer to prepare the surface. Water-based primers provide excellent adhesion and a smooth surface for the next paint coat. They also prevent peeling and efflorescence. This product is suitable for interior and exterior use.

While it may seem like a waste of money to apply a primer before painting over plaster, the results will be worth it. If you’re applying the first coat of paint on a plaster wall, you don’t need to use a primer. Using straight paint has never led to a fallout, but the use of a water-based primer on your plaster wall will ensure good adhesion and ease of application.
Water-based primers are also ideal for interior surfaces, although it is important to wear protective eyewear and ventilation when using any type of primer. To avoid any harmful effects, clear the surface of old paint before applying the primer. After that, sand it flat. Once the surface is flat, stir the primer thoroughly and apply several thin coats. For smooth, even coverage, it’s best to apply multiple thin coats rather than a single thick coat.
Latex primers can be used to even out the surface of wallboard or patched areas. Latex primers can cover minor stains. While latex primers are not as durable as oil-based ones, they are water-soluble and easy to clean. You can also find low-VOC formulas of latex primers, which are considered healthier alternatives to oil-based ones. When using latex primers, make sure you do not overuse them.
Oil-based primers are less expensive than water-based ones, but they are less suitable for most interior applications. They can be applied too thick and leave brush marks. They also emit strong fumes, which are hardly desirable if you’re planning on resale of your house. However, the downside to oil-based primers is that they will stick to many surfaces, so you’ll need to thin the mixture thoroughly before applying it.
For painting walls made of plaster, you will need to use an acrylic primer, sometimes called an acrylic undercoater. It is important that this primer is 100% latex or acrylic. After the plaster has dried for a month, it is time to apply a second coat of paint. Because plasters can be thirsty, you will need two coats of primer before you can apply the actual paint. For best results, you should start by scraping off the residue from the old plaster before applying the primer.
The EPA recommends using acrylic primer, which is water-based and kills bacteria, moss, and fungus on walls. It is an excellent option for interior plaster walls because it doesn’t contain colorants and is safe for use in bathrooms and laundry rooms. Additionally, it has a high-gloss factor that hides light stains. However, if your walls are particularly porous, you may need to use two coats of the primer before you apply the new paint.
Although latex primers are generally less effective than oil-based primers, they still help in leveling out the surface of patched areas and wallboard. These primers also help in covering up minor stains and blemishes. Though they don’t offer the same degree of protection as oil-based primers, latex primers are generally water-soluble and easy to clean. There are also many low-VOC formulas on the market, which make them a healthier alternative to oil-based primers.
Oil-based primers are the industry standard for decades. Both latex and oil-based paints can be applied with this primer. These are widely applicable to a variety of surfaces, including metal surfaces, wood, and interior walls. Additionally, oil-based primers are excellent stain killers. A thick coat of oil-based primer will help the paint stay in place even when stains are inevitable. If you don’t have the time to use an oil-based primer, try acrylic or latex primer.
Plaster walls are more prone to dents, holes, and cracks. Before applying the primer, fix any imperfections. Use paintable caulk for smaller cracks and dents and sand the surface smooth before applying the second coat. Sandpaper will also help you achieve a smooth surface before applying the primer. If you plan to prime a plaster wall, make sure you’ve sanded it down first.
Painting a surface such as wood or plaster requires the use of a plaster primer. Primers are specially formulated paints that help adhere paint to the surface. They also help block decades of stains from bleeding through. It is recommended that you let the primer dry completely before painting. However, if you are planning to paint over an old plaster surface, it is better to use a new primer. For this, it is best to use Dulux Trade Drywall Primer Sealer or Supermatt.
Depending on the type of surface, wood primers are available in different types. For plaster walls, you should opt for stain-blocking primers. These primers are best for plaster walls because they have superior stain blocking properties. Moreover, they fill and seal the plaster surface. You can choose oil-based primers like Kilz or Sherwin Williams. Choosing an oil-based primer will also help you protect your walls from stains.
Water-based primers are available in different types, including emulsion, solvent, and epoxy. They have good crack resistance and are suitable for bare wood and drywall. These primers have good adhesion and are suitable for new surfaces such as bare wood. If you’re planning to use it on metal, choose a red oxide primer. These primers can be used on metal and porous surfaces that rust easily. You can also use stabilising solutions to prime porous and powdery surfaces. Alkali-resistant sealers should be applied to lime-based materials.
Oil-based primers work well with oil and latex paints. They are also useful for interior and exterior wood. They seal porous surfaces and help paint adhere to them. Moreover, they prevent tannins from penetrating the paint, preventing blemishes and stains from forming. This type of primer prevents rust as well. They also make the topcoat adhere to the wood and protect it from moisture and stains.
Water-based primers are not suitable for use on wood because they don’t penetrate deep into the wood. These primers may cause wood fibers to swell and make the surface uneven. Another problem with PVA primers is that they don’t block tannins. Tannic acid is a natural substance found in many plants. If it penetrates the surface, it will show through and may even cause light-colored wood to appear yellow.
