Sand cement render over old existing scratch coat

[loky11]

Hi guys, just need abit of advice off you lovely bunch of spreads, will it be ok to topcoat over old scratch coat? Customer has hacked off old topcoat (pebble dash) and has asked me to patch scratch coat where needed then topcoat and pebble dash again. Tia.

Yes. Use something like Everbuild Rendagrip and let fully dry then carry on as normal.

No problem just make sure all the dust is off the wall.
