Engraved sandstone

[Peter J]

Just in the middle of engraving a large 40 mm thick piece of sandstone, engraving seems to going ok but not having done this type of thing before concerned about how to paint fill, think i have got about 2 mm depth on engraving 

 

anyone got any advice?

A brush and a steady hand?

Assuming you can't clean up like you would on a smooth material, I would have thought a Flo pen would be the answer.

Or get some of those syringes you refill printer ink cartridges with.

Thin down cellulose paint or try the acrylic paints from 908ltd

I've done some sand stone before, never had to infill it though.

 

I hope none of the middle of letters pop out, its very soft and liable to do so.

 

Good luck (don't mean that sarcastically even though it sounds it!)

Spoke to a monumental mason, his suggestion was use plenty of paint fill the engraved area 3/4 times until full, dont worry about paint on the surface, when the paint is fully dry using either a piece of sandstone or an abradent pad rub down the whole plate until all surface paint is removed while keeping the area wet at all times.  Paint applied today, rubbing down tomorrow.  Let you know if it works, hope so have invested a full days work in it so far.

Rubbed the plate down with a heavy sandstone block, worked very well, only problem was that i had not gone deep enough with the engraving probably needed at least 6 mm, but, for a first attempt pretty successful

Thanks to all for the advice.
