How Many Coats of Primer Do I Need
While it is true that paint can stick to wall without priming it prior, there is a high risk it will be blotched, cracked, or peeled away. Primer is a material that consists less pigment and more resins compared to paint, with other additives such as solvent.
It controls the amount of paint absorbed by a surface so you need less coats of paint to accomplish even finish. Primer only costs half of the paint generally, thus you may be able to cut some budget.
Choosing the correct type of primer is not less important that picking the type of paint to use. Here is the recommended amount of primer coat to avoid marks, stains, and blotchiness in the new paint on your wall:
Single coat layers
If you’re going to paint over plain white or extremely light paint color, one coat of primer usually will do its job. Painted surface is prepared to receive other layer of paint, so you do not have to be concerned to see the light bottom coat showing after final coat.
Meanwhile for self-priming paint, as the name suggests, does not need primer. However, there is no harm if you want to use a single coat in advance.
Double coat layers
Majority of unpainted surfaces will need double coat of primer. Some surface areas might be more porous compared to others if they’ve never been primed or painted. They absorb paint in different rates and lead to blotchy painting.
Using double primer coats can be a problem solver for this particular issue. The first coat will be absorbed by the surface, and the second one will work by patching the remaining spots.
How Many Coats of Primer On Drywall
You can definitely get true paint color that long-lasting for years if you use the correct type and amount of primer. If you are not sure about the amounts of coats needed by the surface, you might ask for an advice from paint store.
Alternatively, you may begin with single coat layer and then check after the surface has dried. Apply another layer coat if it is still heavily color, porous, or rough.
Exactly how many coats of primer do you need for drywall? Start with one layer of primer sealer for drywall. High-build drywall has thicker consistency than basic formula, thus able to offer better coverage. Check for any imperfections like nicks, bumps, or thin spots after the layer has dried.
To cover those, you may need second coat layer. However, if you use high-build primer, you may find the result decent enough already after a single coat.
How Many Coats of Primer on Painted Wall
For light to medium old paint wall color, such as mint green or sky blue, start by one coat of primer. It also applies if your new paint color is plain white or really light toned. If you see the previous color shows through even after the layer has dried, you need to add another coat of primer.
Another option that might be worth to try is using tinted primer. This type of primer can neutralize color underneath how many coats of primer you are intended to use.
