hi ,i power washed a driveway and sanded want i thought was right but some sand as blown onto it when i was sealing i have use xlyene from pics. as asking if anyone could tell me there tips how to remove this. i have a few ways i could do this .

also some of the joints are not want my customer wanted on the big gaps i have put in sand level with the blocks.

The only way to get the oversanded joints back as best you can is to wet the joint area with thinneres (Xylene) leave a couple of mins to soften the resin, then use a thin wire brush and scrub the affected joint until resin and sand turn into a thick gloop and scrape it off with a rag and discard, just top the area around joint up with a 50/50 mix resin and thinners.
as you can't effectivley get all the resin remnants off as if it had just been washed you will still have grains of sand mixed in with the resin. The sand grains always show up like a sore thumb.

The only way you can justify the sand grains on surface is to tell custy that it's there as an anti slip measure as you don't want anyone sliping and getting hurt

It must be a smooth block surface youv'e done? Probably clay paviours, if they are then you will probabli get te resin unbonding from surface in next few days as oidinary block resin molecules wont bond to clay pavoiurs as there too dence.

This is why I don't seal any more, I wan't to sleep at night!

hi thanks for advice will do that with thinners.he want like that if i say it will stop you slipping. my joints of sand had more sand in them than his. there were sand on blocks etc.

justs picked and picked on it .but i will get it right for him the big gaps i will rake the sand out.

Mark,
I meant the sand left on the block surface! as a non slip measure, worth a try

hi hes a builder that will not pass with him.it was a bit windy and only some sand got on the blocks. but with the gaps he says there is to much sand in them cant win.

The thinners and wire brush will get the oversand out the v in the joints

Hello, when I seal a drive I use a petrol blower after sanding to remove the excess sand and I also use a wide bass broom

i too use a blower but it often removes the sand from the joints if you don't get the angle and engine speed just right. also the sand is so fine it tends to go up in the air and resettle behind you. do you find this?

thanks for tips. done the job again yesterday and its come up good.use the thinners on the joints and then wire brush them.


yes i have found that with a blower thatsm what i did with these job. also i been told you can put a thin layer of xylene seal over before you sand this helps the sand in the joints better. as anyone done this before.
