Primer or hanging primer: what are the differences?
When preparing a surface before painting, you often hear about primeror bonding primer. Both are products designed for preparation… but they don't serve the same purpose at all. To avoid mistakes and guarantee a flawless result, here's what you really need to know.
What is a print painting?
Primer paint (often called "primer" or "primer undercoat") is designed to regulate the porosityof a substrate.
Its main objective is to create a stable and uniform base before the finishing paint.
It allows you to:
-
Block the background: prevent the wall from absorbing too much paint.
-
Standardize the substrate: reduce differences in absorption between repaired areas, old layers or varied materials.
-
To ensure a more uniform finishof the final paint job.
-
Therefore, we use a primerwhen the surface is porous: plaster, plasterboard, render, repaired walls…
What is a bonding primer?
The primer, on the other hand, is designed to make the paint adhereto surfaces that do not naturally "stick".
It is used for:
-
Create a mechanical attachmenton smooth or closed surfaces.
-
Allows painting on difficult materialssuch as tiles, melamine, PVC, non-ferrous metal, old glossy paints…
-
Avoid peeling or blisteringthat occurs when the finish does not adhere properly.
A bonding primeris chosenwhen the surface is not absorbent, but on the contrary too smooth.
