It is imperative to apply primer to any surface that we want to paint. Priming is a very important step in the painting process. Not only does it help the paint bind to the surface, it will give your paint job an appearance of uniformity without cracks. The primer has to be applied before painting either on the outside or inside surfaces.

Before you use primer for different surfaces, clean the surface properly. There are so many types of primer available in the market. While you use a primer for different surfaces, you have to understand what types of primer are available and what they are intended for. Some are manufactured to bond well with metal surfaces, while others are formulated to work with masonries, i.e. brick walls. Choosing the right type can make a huge difference as far as the final painting is concerned.

The table below gives the information about what types of primer should be applied on which type of surface:

01. New Unpainted Wood Surfaces:

Most paint manufacturers make a good wood primer. If the wood species don’t leach tannins into the paint, use either latex or oil based exterior wood primer. For woods that can stain the paint, apply an oil based primer.

02. Painted Wood Surfaces:

First scrape all loose paint and bare sand spots, remove all chalking with a damp cloth and let the surface dry. If you can’t remove all the chalk, apply an oil based primer.

03. Damp Wood Surfaces:

For damp wood, acrylic latex primer is useful. Damp wood has little bit moisture in it. So every primer is not effective for damp wood.

04. Dry Wood Surfaces:

For dry wood alkyd or oil based primer must be used. The oil based primer tends to stick well with dry wood. The durability of oil primer increases with the dry wood.

05. Metals Surfaces:

If metal surface is rusty, remove all the rust and apply high-quality oil or latex primer.

06. Masonry Surfaces:

On new masonry, or older porous surfaces, use a latex primer. On previously painted masonry, you need to seal only spots where the old paint has been removed during surface preparation or by weathering.

07. Aluminum or Galvanized Iron Surfaces:

Remove any white, powdery oxide using a non-metallic scouring pad or abrasive. Then apply corrosion resistance latex or oil based primer.

08. New Drywall Surfaces:

For new drywall, apply water-based primer or latex drywall primer. Drywall primer will fill all minor defects in the drywall job.

09. Stains Surfaces:

Water stains are best covered up by oil based primer. Apply two or three very light coats, so they dry quickly. Stains from fire, rust, etc. can be extremely difficult to get rid of.  They can be easily by removed shellac primer.

10. Smoke Damage Surfaces:

Smoke damage is best covered with shellac primer. No other primer will dry quickly enough for the smoke damage to not come through. Latex primer will work but it will take at least two coats to stop the smoke damage from coming through.

11. Patches Surfaces:

If there is a tone of patchwork, the best thing is to use latex primer on the entire wall or if you just have a few spots try a few light coats of oil based primer in a spray can.

12. Chalky Areas Surfaces:

Any chalky areas will need to be power washed. It can be covered with an excellent latex primer. The latex primer will bond like glue.

13. Extreme Colour Change Surfaces:

For going from a dark or bright colour use latex primer. For significant colour changes, a primer is absolutely necessary for you to achieve your desired result in a reasonable amount of time.
