Rated 5 out of 5 by Keeps water out There is little else to say, mix it right and it keeps the water out, just on the prices side but does the job 1 Jan 2016
Rated 4 out of 5 by Mixed for a pond wall render Well this is a partial review as all I've done is apply the coat of render to the inside wall of the pond. Good points so far - the light yellow colour stays in the mixed water solution 1:10 ratio. but does not colour the mix of 1 cement to 2.5 rendering sharp sand. These ratios seem hard to find on directly on the web. It mixed in fine and looked to be quite workable for at least 2 hours, i'd finished by then. I used about a 1/3 of the 5 litre bottle for two bags of rendering sand and just under a bag of cement. so perhaps (my guess) around a square meter of wall for each litre used. Will it do what its meant to? only time will tell. but its well recommended elsewhere and specked for the job. 11 Mar 2015
Rated 5 out of 5 by Perfect product High quality product from sika, Follow the instructions exactly and leave in the mixer until the right consistency is reached. Blocks water forever! very strong when used with stainless expamet. 14 Apr 2014
Rated 5 out of 5 by Trusted brand If you have damp problems and need a permanent cure then Sika 1 is a product that works! Simple to use, just have to add to water and use the diluted sika in your render mix. If you follow the ratio correctly then you will have a waterproof render barrier, essential if you are for example tanking a basement room. 31 Aug 2012

Yes it can be painting provided its dry and fully cured. Apply paint as recommended by the paint manufacturer and trial in a small area first to ensure compatibility but the cured mortar or render will not react differently with Sika 1 added as an admix.
