WALL PREPARATION · USA
Before painting new drywall,
prime it right.
Primer evens out drywall absorption: your paint goes further, the color stays even, and you stop paying for a heavy first coat.
Orientative estimate at 350 sq ft/gal per coat. Confirm the coverage of the primer you buy.
NO FINE PRINT
Priming new drywall is not optional.
Fresh drywall and joint compound absorb paint unevenly. Without primer, the topcoat dries with blotchy sheen and color variation — and you end up using more paint to fix it.

COMMON QUESTIONS
Before you open the pail.
How much area does a gallon of primer cover?
At PintaClaro's practical reference, one gallon of all-purpose primer covers about 350 sq ft per coat over porous drywall. Denser, previously painted surfaces can stretch further.
How many coats of primer do I need?
One coat covers most jobs: the goal is to even out absorption, not to build a thick film like paint.
Can I paint directly over primer?
Yes, once it is dry to the touch per the manufacturer's label (usually 1-3 hours). The primer is the base ready to receive your topcoat.
Can primer work as a finish coat?
No. Primer is not formulated to stay exposed: it does not resist washing or wear. Always apply paint over it.
