Hi Chaps, I layed a block pave job about 3 or 4 weeks ago, I went back to top it up with sand and now the guy want's it sealed. What type of sealer would you recommend, it was just a standard brindle block
cheers

For me that time gap after laying the paving is too early to seal, I would leave it for about 4-6 months, in case any eflo starts coming through. And it is too damp & cold at the moment anyway.

With the temps & dampness at the moment it will be your worst nightmare.

to cold to seal, effloressence needs to come out if there is any in the blocks, may at the earliest to seal MSH

as previous posts say don't even think about it until at least may, if you seal any time now you will be called back out to the job, as roger said 4 to 6 months down the line the blocks will have had time to set & dry out, and the weather will be just right

Hi Loubag
I have to disagree with all the advice given already.
To start with the paving can be sealed as soon as it has been laid, I have done hundreds of drives this way and never had a problem with efflourescence, once the paving is sealed the efflo cant possibly come to the surface.
And secondly unless you are using sealers that are cheap rubbish, as long as the paving is dry and the temp is above 5 degrees it is not a problem.
I have sealed hundreds of drives/patios of all different types all year round not just spring/summer as a lot seem to do. I have sealed jobs on christmas eve and in the middle of Jan and Feb with no problems.
The main point is to use a good quality sealer not some rubbish from B&Q or a builders merchant.
Hope this helps
Drew

LOUBAG here lol. I don't know what to do now. I went back to the job today and eflow has started. Can you seal straight over eflow blocks or do you wait and they return to their original colour. Kind regards, LOUBAG

hi drew and welcome to the brew cabin
so you are disagreeing with almost 99% of the men on this forum who do this work for a living year in year out
I agree about using a quality sealer,this has been covered ad nauseum on this forum
but i feel it is a very bold opening gambit to say that sealing will stop efflorescence coming to the surface
pull your chair forward get a cuppa rosy lee and read this
cheers LLL :;):
