Marker pen showing through paint

Marker pens are notoriously hard to seal. The best thing to try is a leafing aluminium paint, in other words a paints that has a very shiny silver look, not the metallic aluminium look. Some of the spray can manufacturers have this silver and it will seal the marker pen.

The metallic silver used in these paints floats to the surface and the aluminium platelets (leaves) overlap and seal anything underneath. Also excellent for sealing water stains in plasterboard, ie in ceilings.

It it horrid stuff.

Thanks Rod

Maybe I will just chip, or angle-grind the brick away. Then re-fill it. Its only about the size of a 50c piece.

Gday there,

Buy a can of Zinzer Shellac based sealer. About $13 bux. Comes in a spray can which is red and white. Shake it well, give it a squirt, then another when it dries up (about 5 mins). Guarantied!

Im sure that will help.

It works well, but I didn't know it came in a spray can. Thanks, I'll get a can.

metho based sealer...will dry very-very-very fast. 100 or more kids bedrooms, works like a treat everytime.

it seals water stains too

Well,

Thanks again everyone.

I am sure that there is something that works well in there.

Cheers

Just paint some oil based paint over the pen mark and allow to dry for 24 hours. You can buy in a spray can form which saves you having to clean brushes. When building anything in the future being anything from timber to plasterboard, use pencil as it can be painted over with acrylic paints.
