Mixing hydroflow

Adding colour
Use any water based pigment e.g. resi-TINT acrylic inks, acrylic paints or powdered tempura paints, any solid can be added such as sand, mica, quartzite, dried shards of hydroflow.

Making the shards
Mix and pigment the hydroflow as shown below and then spread thinly on a sheet of plastic / aluminium foil / cling film. Allow to dry then peel and crush by hand into the desired size and shape.

Adding the shards
Only add the shards into the mixture just before pouring.

When using the whole kit
Add colour to the hydroflow activator fluid before adding the powder. Add small amounts at a time and mix in stages until you have achieved a lump free consistency.

When using part of the kit
Pour the desired amount of hydroflow activator fluid into your mixing container. Add colour to the hydroflow activator fluid before adding the powder. Add 2.5 times the amount of powder to the fluid activator e.g. if you started with 100ml (100g) activator fluid then you should add 250g powder. 2.5:1 is the default mixing ratio, but this is not set in stone. You can adapt the ratio with less or more powder to obtain a thinner or thicker consistency to suit the application. If the mixture is too viscous and thick for your application simply add a little water (5-10% by weight), the activator is a water based emulsion and can be extended and diluted further to make it more fluid.

Once you have mixed to a creamy consistency you can top up the pigment addition to achieve a stronger colour shade.


Add the terrazzo shards, immediately pour into your mould and agitate to clear trapped air bubbles. Allow to harden in 40-50 minutes. The mould will feel warm, this is normal. De-mould after 1-2 hours.

Drying / De-moulding & Sanding
Allow 1 hour before de-moulding and 12 hours before sanding. Use a fine-medium grade sandpaper to expose the terrazzo shards, wet & dry sanding is particularly effective. Flush with clean water to remove dust.
