Hi folks, I have searched lots of places for advice on the above subject to no avail. I know that PVA is generally regarded as a no no, however what about waterproof PVA is this regarded with the same disdain. Also my tiling adhesive recommends Acrylic primer - but can I find it anywhere - is there a screwfix substitute ? Any help greatly appreciated.
screwfix do an acrylic primer http://www.screwfix.com/search.do;jsessionid=KFE5HSI55KVVECSTHZPCFFA?_dyncharset=UTF-8&fhsearch=acrylicprimer
I didn't think that it would do. The usual DIY wharehouses don't seem to have the stuff and I really don't want to throw ant money towards Topps Tiles so thought someone may know a reasonable online supplier. Thanks again Ali
What you need is Balbond SBR (not cheap) but absolutely the mutts nuts. http://www.bal-adhesives.co.uk/bal/pdfs/specifier_literature/Bal_Fixer_Guide_Jan2006.pdf
Unless I am mistaken, Bal Bond isn't suitable for use as a primer on Ply wood flooring as Bal don't recommend using a primer with their adhesive on floors.
If you check the link above to the Bal tech pages they recommend priming ply (on the reverse side) with Balbond SBR. It's basically a belt and braces approach to prevent the ply warpimg or cupping due to moisture ingress.
I understand that Bond should be used on the underside and sides but they don't recommend on the top (do they?) Surely this is what the OP is asking?
Cheers folk, The ply is already down and 30mm of the stuff with about 1200 screws so I aint taking it back up to coat the underside. Any advice on the laying of the underfloor heating - do you always screed with self leveling compound or just imbed it into the tile adhesive? I am using 3mm devi floor mats. Cheers Again
I would float the floor with a slightly wetter coat of Rapidset flexible tile adhesive, tile the next day, or you could use arditex 2 part self levelling compound.
Thanks for that, The company I bought all my tiles off of just recommended that I use a thicker layer of adhesive in order to incorporate the UHF into the floor and tile straight away with no initial first coat - I assume this is a no no. I have some bags of flexible adhesive that was left over from a previous project that is different from the Granfix stuff that I bought to lay the granite - could I use this as my UHF layer and then use the granfix stuff on top ot is this just asking for trouble ? Thanks again in advance. Ali
