S1 v S2 and general flexibility!

[LEFT][LEFT][B][FONT=Arial]This should really be a Forum for Tilers, not a place for manufacturers to plug their products but there seems to be a lot of references to S1 adhesives lately and a lot of confusion out there so here's a short version to clarify![/FONT][/B][/LEFT]

[LEFT][B][FONT=Arial]Firstly, S1 and S2 are defined in BS EN 12002:2002 as additional classifications for adhesives. In effect, they describe how much an adhesive will deform in order to accommodate a limited amount of movement after tile fixing. But, these are optional standards and no adhesive has to meet either classification.[/FONT][/B][/LEFT]
[LEFT][B][FONT=Arial] [/FONT][/B][/LEFT]
[LEFT][B][FONT=Arial]In simple terms, an unclassified adhesive might or might not be as deformable and you just won’t know until you try it. If its S1 rated, it’s deformable. If its S2 rated, it’s even more deformable. However the deformability test does not take into account flexural strength as part of the test - which manufacturers more often use to promote ‘flexibility’ of the adhesive - nor does it test adhesives with elastomeric properties (such as BAL Fast Flex) which exceeds the S2 requirement by a factor of three! [/FONT][/B][/LEFT]
[LEFT][B][FONT=Arial] [/FONT][/B][/LEFT]
[LEFT][B][FONT=Arial]We’ve been making all of these adhesives for years and therefore have no reason to push fixers towards any particular product. Some applications require greater flexural strength in the adhesive and some will require greater deformability and the two can easily be confused. If we’re asked which is best, we ask for details of the job, then say which is the right type in that case. If anyone wants to know all the technical details, just call us on 0845 600 1222.

[LEFT][B][FONT=Arial]Hope this helps to resolve your queries ...Happy fixing![/FONT][/B][/LEFT][/LEFT]

This is a Tilers forum.....and any manufactures on here promoting products are actually sponsors of the forums dave and pay for the privalage of doing so...
BAL products are also heavly promoted on here as well by many members ( tilers ) who use them along with many other brands...that is whole purpose of a tilers forum to give feedback on products that tilers use and what they like using...is it not.. as well as other advice...

The man BAL TAS Dave is apologising for the fact he may seem to be plugging his product he is not getting at the forum. The operative word is BUT did everyone miss it or just fail to read it properly
