Will be laying 15Sq m of calibrated limestone stone shortly,is it worth adding SBR to the bedding layer mix or not?If so what proportions should it be mixed at?And what make is recommended or are they all much the same?

ronafix is the best but at a premium cost
i normally add about 100ml to every gauge it just seems to aid adhesion with natural stone
