Putting wire netting in a floor screed

[Saycheese5]

I am repairing part of a floor screed that was cracked and hollowish. The area is about 3 square metres. The thickness is however about 35mm. I want to wet the concrete, then apply a coat of PVA for better bonding, put down wire netting and then lay the screed (4 parts sharp sand to 1 part of portland cement).

My question is, shall I lay the wire netting (or chicken wire) on the scabbled concrete first and then lay the screed on top of it or should the netting be in the middle of the screed?

Thank you.

The mesh needs to go somewhere near the middle of the screed.

It won't be doing anything if it's right at the bottom.

You have a terrible job trying to lay mesh in just 35 millimetres of screed. It will keep coming up above the surface

First you do not want plasterers sharp sand. Various parts of country, various names. Grit sand, Concrete sand, Course sharp, Flooring sand. Screed sand being a few. The sand needs to have fine particles of 2 to 3mm of grit stone included in the grading.
Waste of time throwing mesh in a 35mm thick screed. For a 35mm thick screed you really need a modified screed with SBR bonding and polypropylene reinforcement fibres.
Google both the above and you will have all the info that you require
