Hi, I've recently had a render job done with PRB TCR - and after 2 months I've got loads of crazing and weird yellowing/red staining on the surface.

It was applied with basecoat, mesh, primer and then top coat, 10mm beads on dense block

Anyone got any ideas why it's ended up looking like this?

Did you dilute it down at all, put it on pissy wet?

Was the substrate fully dry when applied?

Are they the tops of garden walls or small parapet type walling in garden..... then the top of the vertical off the top of the wall...?

Show the application from further away.....

Do you live in the sticks?

It wasn't applied by myself, I paid a local rendering firm to do it for me. I purchased the materials with good intentions and decided to get a pro in to do it.

id say it was laid on too thick and not watered down.
if its not rubbed in properly and then the sun cooks it it can skin over amd create that look as there hasnt been any moisture in the application

I always tell folks straight with these kinda outdoor designs that things aren’t gonna be perfect for long and there maybe maintenance to do to keep them looking absolutely beautiful all the time , just a smal example would be normally a render is on a side of a house and usually has plenty of clearance from the ground so when there is bad weather of all the seasons the house would hopefully look brand new for a while , small dwarf wall modern designed areas is a different cattle of fish
