Thanks for the replys, have the data sheet for the screed, and am having first site meeting today, have made the customer aware of the importance of following the spec to the letter.
Very impressed with Kerakol Bio gel and have spoke to their rep and tech people about anhydrate screed prep.
Their solution is quite simple with usual sanding, dust removal and two coats of their "A" primer, effectively creating a barrier to which the bio gel fixes. Max 8m linear tile runs before expansion joints, and expansion joints through thresholds. Was planning on using a clip system for a bit of overkill too, a 15mm trowel and back buttered obviously too. On a flat screed that should cover most bases.
However, site visits usually reveal a few demons. Will hopefully pass the responsibility of moisture content/screed dryness to the customer, as still feel an accurate testing procedure or kit is hard to rely on.
Unless you guys have any cost effective solutions you rely on that you can suggest.
With that in mind, one tiler, one labourer, not including prep, including materials any thoughts on price? 40, 50 pound per metre?
