Laylandi Tree Sap...Stained Indian slate, Help advice needed please

[Andrewmpalmer2003]

Hi all,

 

I left 20-30 Laylandi tree logs for a friends dad on his Indian slate in his rear garden. Now I'll always put this on a sheet or on the lawn.

 

From the title it's stained his Indian sandstone slate, he has tried most things to remove the sticky sap and stain.

 

Any advice would be very welcome indeed.

 

I'm going to contact HG international on Monday however any help or tips would be great.

 

Kind regards

 

Andrew

You could try spraying a can of wd40, wait till it starts to disolve then wash with a jet wash

You need brick acid, proper brick acid, not the crap they sell in DIY stores. It's restricted sale these days like creosote so have to blag ya builders merchant as I believe most of there policies are account sales only.

Failing this there is one other option. Obviously if laid in sand(uncommon for slate) turn over, dress edge if needed,and relay and point. If not its possible with Indian slate to remove the top layer with an old trowel and hammer. I had to do this once when I was rather careless with a disc cutter. You have to be super careful. If you get it wrong its terminal

You could try eucalyptus oil. It works amazing on tar.

Traffic film remover may work, it seems to lift the residue on the rear of our chip boxes. Try a small area first thouigh.

Something with citrus in will do the job. Tried and tested, I did pretty much the same a long time ago.

Had a similar problem with staining from brash on a render wall from a groundie being careless. Managed to shift it with a paste of biological washing powder applied and kept moist to allow it to work, followed by a good scrubbing. This was only from copper plum leaves might it could be worth a try. Good luck with it!

Brick acid won't damage slate. If your concerned test it on a corner, but it won't damage slate.
