Dear All
Mapeker has been tested for use on either overboarded existing timber bases i.e. minimum 15mm exterior or WBP plywood screw fixed at maximum 300mm centres over an existing timber base screw fixed to joists OR underfloor heating (not under tile unless on a solid base and encapsulated in a suitable self leveller systems and found to perform satisfactorily.
Basically we have been under selling the product!!
However Keraquick is rated S1 to EN12002 in terms of its deformability. It is a higher specification product and its adhesion and flexibility will be better and its water absorption less than Mapeker. Hence it can be used to tile on to under tile heating without the requirement to encapsulate with a levelling screed
Keraquick is a better performing product in given exacting conditions. It can be used on to under tile heating over a plywood overlayed floor where as Mapeker is for eitherunderfloor heating (timber) or under tile heating (solid structure) but not both in combination.
So it depends on the job and subsequent service conditions but Mapeker can give a more cost effective option to the customer in certain conditions.
