Regenr8 tile adhesive is a single-part, flexible, standard-setting cement-based adhesive for wall and floor tiles, suitable for fixing ceramic, porcelain, and natural stone. Single-part – or S1 - simply means that the adhesive has increased ‘deformability’, ie it can stand a certain amount of compression and stretch – making it ideal for use where your substrate may bend or deform slightly (we’re talking milimetres, rather than centimetres, so you still need to be careful.  For areas where there is likely to be more movement, use our fast-flex adhesives).  ‘Standard setting’ simply describes the length of time the adhesive needs to cure before you can grout and subject your mosaic to any wear and tear.  This adhesive sets in 16 hours and can be grouted after 18 hours (based on a working environment of 20˚C). The adhesive has a pot life of 2 hours and an open time of 30 minutes (pot life describes the period of time during which an adhesive – or grout – maintains its workable properties after it has been mixed.  Don’t try and add more water after this time is up!  Open time is the amount of time you have between applying the adhesive and getting your tiles stuck into it).  You should always apply the adhesive in dry conditions, but it is very resistant to water (and frost) once it has set.   The adhesive is supplied in a plastic carton. Mix up at a ratio of approximately 4:1 powder to water (by weight). Add the adhesive powder to clean water in a suitable mixing bucket and mix thoroughly to give a lump-free, easily worked consistency. Once mixed, the adhesive is immediately ready for use. Ensure that your substrate is completely clean and dust free.  To cover an area 1m² you will need around 4kg of dry adhesive.  Regenr8 uses a compound of recycled materials in the place of standard sand, thus massively reducing the need for naturally-extracted sand, which is typically taken from beaches and riverbeds.
