Never used renovation so cant compare but as for method prine screed prime glue I always prime before glue due to 700 being dusty
Used both. 700 is a better product IMO but too much money compared to others out there. Renovation is good, not as quick drying but I always leave a day between fibre screeding and fitting on them. I prime on all screeds before glueing.
Same as Daz I've been using level flex its Super cheap & decent gear ! 700 is the best but a rip off & renovation is crap IMO ! Prime, screed & then polish with my rotary machine & a sanding disc then glue ! This gives a better surface to stick to especially on dusty screeds. I even polish feather finishon ply unless its a small area because its dusty to.
Have you tried a ceramic tile wholesaler's ? It made by tile master (I think) who make grout & tile adhesive !
