Do you need to seal bare plaster before painting?

[kj2801]

Long story short all the paint completely came off wall in huge pieces and now the wall is back to the bare hard plaster. The walls are masonary with a render/hard wall plaster. Before painting I know that I need to seal the plaster first (Dulux Sealer Binder) but do I need to also use a Primer after the sealer before the top coats?

Hi @kj2801,

You're correct that Dulux PRECISION White Sealer Binder is the correct product to use. No additional primer is required over it before top coating with a water or oil-based topcoats.

Here's a helpful step-by-step guide: How to paint a room.

Please let me know if you have any questions.
