Why Use a Primer on New Plaster?

New plaster is porous and can absorb moisture and paint unevenly, leading to blotchy finishes or paint peeling over time. Using a primer helps to:

• Seal the surface, preventing excess absorption of paint.
• Enhance adhesion, allowing the topcoat to bond more effectively.
• Improve the final aesthetic, resulting in a uniform finish.

Here in Greenwich, local conditions can also affect how paint dries, which is why a good primer is essential.
