Thanks.

Can't help you with chalk marks but you not the only one who does not care for footy. In fact I didn't know who was in the grand final till yesty arvo when someone asked me who I thought would win

Footy? what's footy?

NT, if it is really "chalk" a pencil eraser will take it off. For a large job like that it might be a bit tedious, you might want to buy a big roll of art eraser (putty rubber) for that.

Are you sure it is not some sort of wax crayon? That could be tougher.

what final??

normaly the marks indercate the underside of the boards.

A card scraper would take the least wood off?

Maybe you should get a Geelong player to do the job.
They wiped P/A all across the G

Thanks for the input guys.

I tried most of those options, but in the end I had to sand the Z's out . The chalk was to far into the grain.

Wiesyboy - You're in the biz so I expect you are normally right... but on these boards the bottom of the boards were shaped with two grooves running length ways. The top had the Z's. Every board.

OK - for next time, a compressed air gun fired with the grain and a fine wire brush on a dremel will generally get it out. Its a painfully slow process but it works.

As for the footy, I watched about 5 minutes and got itchin for sawdust so I went back to the shed. I did listen to bits on the radio.

Cheers

Ah, I should have tried compressed air. Obvious now I look back. But I have one sanded and oiled one room, the smallest, so I can try air tomorrow and see if it helps. The second room also has lots of gyprock dust in it as well.

Thanks.

Chalk normally comes off easily. Is it a wax stick mark, like a crayon? Not sure of your supplier, but I have plenty of reject/seconds floor boards that are marked so with a Z or double line using a yellow crayon. It is extremely hard to get rid of, the best method I've used was an ink erazer, followed by metho and sanding. Even when I think I have got rid of it, my finish often shows the marks back up.

if this is flooring then when you sand the floor from 60 grit all the way upto 180 grit screen back then about 1.5mm + is taken off so those marks will be long gone, before you apply finsh.

I guess the hard way is sometimes the only way.

While we are on the subject, how do you get rid of those stupid barcodes that Bunnings stamp on their timber. This can be a real pain because sometimes the stamp is halfway up the piece of timber you want to use and it takes ages to sand it out. Anyone got an easy way to do this?
