There are two basic techniques to apply colour to concrete. The first is integral color in which liquid colour is poured into the concrete ready mix truck. This method allows the colour to combine with the concrete and the slab obtains colours throughout. The second option is the broadcast method in which colour hardening powder is applied directly to the freshly poured concrete surface. The colour hardener will penetrate the top of the concrete slab 1/8″ and colour thoroughly. Be sure to ask our design experts about our colour options and which method best suits your job.
