Dealing with stubborn stains is hard work at the best of times. But completely covering tough stains from nicotine, grease, water, rust or even felt tip pens can seem like an impossible task. Our Stain Block Primer does just that, covering those difficult stains and blocking out the smells that come with them, permanently.

So, if you’re struggling to banish stains and smells from accidents or damage, here’s our 3-step guide.

Step 1 - Prepare

Thoroughly clean the damaged surface before you start. It will help your repair go more smoothly and last longer. So, make sure the surfaces are clean, dry and free from dust, oil, grease and adhesives.

  • If there are cracks, fill them with Polyfilla or plaster filler
  • If there are rust marks, sand the surface and apply a red oxide primer. Treat bare metals in the same way
  • If your surface is exposed wood, then lightly sand to remove any mould or mildew.

Step 2 - Apply

You can use Stain Block Primer as an undercoat for most types of paint, whether they’re water, oil or solvent based. Apply the primer in an even layer with a paint brush or roller at temperatures above 5°C. Make sure there’s plenty of air and ventilation.

  • Stir well and do not thin. When applying, don’t let the primer drip or run
  • One coat should be enough but if you’re applying on a porous surface, you might need another. You can apply the second coat about 45 minutes after the first.

You can use Stain Block Primer inside and out, and on a wide range of surfaces including walls, metal, plaster, uPVC, formica, hardboard, glass and ceramic tiles.
Note: It may not be suitable to use under some polyurethanes, epoxies or some highly-alkaline, special-effect paints (such as flock type paints) or highly-solvent lacquers.

Step 3 - Paint

We recommend you paint over Stain Block Primer with a durable, washable paint, particularly on walls that will face wear and tear. Visit your local DIY store and choose from the widely available range of completely washable paints.
