Cheers for replies lads, church I'm interested what's you're view mate, any knowledge on these materials is much appriciated, I've only used it once on a small job and had a mare trying to use it as a slurry it was like the cement was sinking thru it an had a to keep whisking it thru whilst applying with a brush an roller let alone applying it thick enough to key it up... I've never used rendaid any info on that would be much appreciated to, I don't do much of it so confidence with it isn't what it sould be but any s&c render I have done I've always jus give the walls a light mist with the hose an scratched straight over.. Got 2 extensions over light weight blocks an a gable over face brick work to do , I use 4-1 scratch 5-1-1 top over brick work an 5-1 scratch an a 6-1-1 over block work, cheers in advance for any shared knowledge on these materials:RpS_thumbsup:
