Applying paint over grease stains effectively prevents their reoccurrence
In the quest to keep your walls and ceilings looking fresh, dealing with grease stains can be a daunting task. However, with the right tools and techniques, these stains can be effectively removed and sealed, ensuring your interior remains pristine. Here's a step-by-step guide to help you tackle grease stains.
Step 1: Preparation
Begin by gathering your tools. You'll need a degreasing solution, such as white vinegar, baking soda, or cornflour mixed with water, a sponge, fine grit sandpaper (grade 240 is suitable for most surfaces), painting tools, dust sheets, plastic bags for covering electric sockets and switches, and if necessary, a green scrubber pad for more robust surfaces.
Step 2: Protect Your Space
Lay down dust sheets to protect your floors and furniture from paint splatters and debris.
Step 3: Remove the Grease Stain
Apply your chosen degreasing solution to the stain using a sponge. Gently dab and scrub until the stain disappears. For areas where a roller won't reach, use a 3-4 inch paint brush.
Step 4: Sand the Surface
Sand the affected area until it's smooth, extending slightly beyond the stain and blending with the grease-free area. After sanding, wipe the area with a moist cloth to remove dust, and let it dry.
Step 5: Apply a Stain-Blocking Primer
The recommended stain-blocking sealer/primer for grease stains is Zinsser's product. Apply a coat of the primer, allow it to dry, and then lightly sand, clean, and dry again before applying a second coat if necessary. Fiddes Full Stop is another option for a white stain-blocking primer.
Step 6: Seal the Primer
For painting over the primed surface, an interior/exterior primer, sealer, and stain repellant paint with impressive covering capabilities and recoatable in two hours is recommended. A popular choice is Dulux Trade Brilliant White Undercoat, which is suitable for sealing grease stains.
Step 7: Cover Smaller Areas
For smaller areas of walls and ceilings, a twin sleeve 4" mini roller set (including tray) is ideal. For larger areas, a larger 9-inch roller might be more suitable.
Step 8: Wait and Repeat
Wait for at least 24 hours before painting over the primed surface. This allows the primer to fully dry and bond with the surface.
Step 9: Use Stain-Sealing Paint
To ensure that dormant grease doesn't bleed through paint, apply a stain-sealing paint. Zinsser's Cover Stain is a popular all-purpose stain-killing paint suitable for most surfaces.
By following these steps, you can effectively remove and seal grease stains, keeping your walls and ceilings looking as good as new. Happy painting!
