Sand cement scratch -----polymer render

[franco]

Looking for your thoughts on this guys -

Ive been asked to pebbledash a house (already pebbledashed but old and tired) and their new garage which was built with grunters..........

.....anyway the customer wants to use powerwall but has asked if a sand cement scratch could be used as their base coat is too expensive.

Told her id rather use the base and exposed from powerwall.

any of you guys tried this way?

Powerwalls dashing topcoat is sold as a 1 coat dashing system. If the existing background is solid and stable you could use their fungicidal sealer over the existing and dash straight over. Its available in colours

if you are hacking off then try use their fibre packed base coat. its good stuff and goes off very hard

Hi, ive used mr and powerwall one coat but tbh i always prefer to put a scratch coat first.

In my opinion the one coat is a mess when the sun hits it.

Spoke to poerwall today and they have said it will be ok.
