Hi guys, hope you can help. I've just insulated externally the top half of my house as it's single skin which used to have tiles on the front of it. I used the suitable insulation and fixed the stainless steel mesh over the top of it over lapping it by 100mm, the mesh in question is deep ribbed. Mix's applied are 3/1 scratch with freeflo in it and 4/1 top coat with freeflo and lime in, it's been 3 days and there are hairline cracks appearing where the lines of the mesh are. The render has gone off lovely and solid it's just these b*****d cracks. I left the scratch coat a week before the top coat went on so I'm a little baffeled. Thanks.
