Cement splashed on siding

patrice607September 16, 2012

Just had a paver patio installed and the contractor splashed cement on our hardiboard. Any tips on how to remove cement from fiber cement board?

I've tried vinegar and a soft brush. It helped a little but is very time consuming.

Get a cruddy wood chisel you do not care about wrecking and pop the spots off.

It may damage the paint, but not always.

Yes, use an old chisel or, better yet, try a trowel or long handled paint scraper--anything to scape off the dried concrete. Even a screw driver might work. Good luck!

The sharper the tool the less chance of damaging the surface if handled carefully.

A 'crank neck' chisel would be the perfect tool, but they are expensive.

There is no way I would risk the damage to my 9 inch long 3/4 inch wide crank neck.

Traditional Woodworker has them, but they start around $50 for a 3/4 inch.

Smaller would be much harder to use without damage.
