There are a couple of instances in which you will always need to prime before you repaint.
- If the surface is porous
Always prime your wall surfaces before painting if the surface area is porous. The surface area is porous when it takes in water, oil, moisture, odors, or stains. For example, new drywall is a porous material. Both the paper that covers it as well as drywall mud are jeopardized by water or moisture when they are not secured initially with primer. This material will absorb your paint right into it if you don’t prime initially.
Untreated or clean wood is likewise extremely porous. If you’re considering painting over that old wood paneling in your research or repainting a set of racks, you will intend to use TOA prima initially.
- If the surface area is shiny
Shiny surfaces are difficult for paint to comply with. If the wall is covered in high gloss paint, enamel, or if the wood paneling has been shellacked, you can repaint layer after layer, as well as never have it stick.
While these surfaces will need primer, we would additionally suggest a light fining sand or scuffing ahead of time also. This action will guarantee your wall surface has enough texture so both the prima and paint can stick perfectly.
- If the surface area is discolored
If your walls have any type of stains on them, old water damages, smoke stains from cooking, or candle lights, child “arts,” you’ll wish to use prima first. Since primer acts more like a sealant/blocker, it will secure these discolorations so they will not leak back or reveal through the paint.
Prior to you prime over discolorations, nonetheless, it is incredibly vital in some cases that you deal with any troubles that resulted in the staining in the first place. For example, if you have old water discolorations, make certain that the leak is fully repaired before you paint. It will trigger more problems later on, with staining as the least of those issues, if you do not.
