i want to extend my drive i laid it about 10 years ago with plasmoor red paving blocks if extending with new blocks is there a colourer to make all blocks the same colour/also ive tried keybond in the past to seal jointing sand but because my drive slopes downhill when it rained or i cleaned car with pressure washer it washed the sand out/if i sealed it with resiblock would this cure the problem/the drive will be approx 70m2 how much resiblock will i need (gloss finish) thanks

how big is the existing drive?
if it isn't that big it might be worth taking all the existing blocks up and using them as a band course around the new drive
its nigh impossible to get a seamless join between old and new without taking the old up
never used resiblock so cannot comment on that
cheers LLL

If the new blocks are of a similar colour (albeit not exact), how about creating a break between the new and the old, maybe a black/grey course or two? Sort of like when respraying a car, you can get away with seperate panels being a slightly different age/colour because there of the join ... IYSWIM

The old blocks will have faded (they're Plasmor: they WILL have faded) and weathered, so there's no way to match up with new.
This leaves two options:
1 - do as LLL suggests and use the old as edge courses and/or band courses.
2 - randomise the old with the new and lay them together. This can be surprising effective, giving a more 'multi-tone' look to the pavement.
Joint Stabiliser: if Keybond is washing out, that suggests there's not enough of it been applied or the amount of scour is too great. A quality sealant, such as Resiblock, or JointFix from Instarmac, would be a better option.
Coverage for a gloss finish is two coats: first coat approx 2-3m² per litre, second coat 4-5m² per litre, depending on block type.
