Just been to look at B/P cleaning job,there is an area to be cleaned but they will be adding a further area of B/P IE to make the area bigger. They then want the whole area sealed, which we do. So the question I have is, after laying the new paving am I right is saying allow 6-8 weeks before sealing to allow any efflo to come through? Also I usually use Resiblock, had no problems etc, the paving is undercover but will have a lot of foot traffic (it is a hanger type building, commercial) I tend to feel Resiblock is a bit OTT for this, can you guys recommend another sealer? The pavers are concrete brindle patten.

Hi Roger
Most times I have cracked open a new pallet of blocks I have found efflo to have already appeared on some of them, I presume it's because they have already been sat in a yard somewhere for weeks ?
If you don't want to use Resiblock sealer try using a good quality Acrylic approx £90 per drum or there's a guy on ebay selling ResiNblock Polyurethane sealer for under £100 a drum, his feedback seems ok from other people who have used it, so it might be worth a dabble.
I'm going to try some when i've used my current stock !

Still no progress in the ongoing Resiblock Problem, so I'm now recommending Pavseel, despite the atrocious spelling.
We're just coming into the peak season for eff, so I's certainly leave off sealing new paving until, say May. Another thing you will want to consider: there'll be a noticeable difference in the colouring and texture of the new and old blocks, partly because dyes and aggregates change over time, and partly because of weathering. If your client thinks the new paving will blend seamlessly with the old, they're in for a bit of a shock.

Thanks Tony, I have told them that the new area will stick out like a sore thumb, and not match, as the original paving is at least 10 years old.
