Sealed block paving - Marks on paving

[orson]

Hello chaps,

Quite a time since I was last on here. I've got a problem with a block cleaning and sealing job I did last summer. Briefly, I pressure washed a block paved driveway and patio, it had'nt been touched for years but came up a treat. The owner asked me to give it a coat of sealer to finish it off. This I duly did after re-sanding etc. The job was done properly, everything was nice and dry, it did'nt rain for several days after sealing and it did look good, if I say so myself.

Now, been called back as there a two silver streaks on the surface of the blocks in different areas of the paving. Has anybody ever seen this? I can't think of a reason why this should occur and can't think of a fix for it. Any ideas, solutions out there. The sealer was resiblock patio environmental.

Thanks in advance

there is very little you can do to repair a resiblock problem,the stuff is a law to itself .maybe call resiblock and as a tech guy there MSH

Thanks MSH, its very strange that these blemishes should appear after such a long time, will give Resiblock a call asap.

It must be a big drive as I thought a silver streak was a train. :p
