Frequently Asked Questions (FAQs)
1. Does stain block paint work?
If you are painting in a mixed colour for example or want to treat an interior wall before painting, a stain blocking primer is your best bet. This is the most common solution used by homeowners & decorators, as it allows you to treat the surface before applying a paint of your choice, allowing for greater flexibility.
2. How do I stop stains coming through paint?
The only way to stop the water mark discolouring the paint is to cover the stain with a stain blocker or an oil based paint first. You can then emulsion or paper overit. If you don't create this barrier the water mark will just keep on coming through, however many coats of emulsion you put on!
3. Can you put stain blocker over paint?
My favorite remedy for bleed through/stains is shellac or shellac based primer. Other stain blockers that also work are oil based primer/paints, spray shellac, polyurethane or even wax. By applying any of these products, the stain or bleed through will be sealed and won't penetrate through your next coat of paint.
4. Can you paint over stains on walls?
Painting over the stain may temporarily camouflage it, but most stains eventually bleed back through the paint and reappear. Covering a stain with flat paint requires proper surface preparation with a primer, which blocks the stain from bleeding through.
