Todays' product range comprises

For the Pre-Caster:

CSE NOVA a non-solvent, self-neutralising surface de-activator in eleven controlled exposure depths.

MicroGEL FORTE etching gel for very fine slip resistant texture.

CSE NOVA grade 005 and MicroGEL FORTE are used both separately or in combination for the production of very fine exposure of small fraction aggregates in a face mix.

ARCON Fluid is an admixture specially developed for the production of exposed aggregate, which improves workability and through restricting segregation of the aggregate within the mix, helps ensure even distribution of aggregate to be exposed.

For the Contractor:

CSE Multitop – a premium top surface retarder, used primarily in the construction of in-situ exposed aggregate pavement. CSE Multitop has the added advantage of providing rain protection within an hour of application.

Available in 10 pre-determined self-neutralising exposure depths, CSE Multitop is non-solvent based product with no hazardous residue.

CSE PRO – is a solvent based surface de-activator for use on mould and shutters, particularly on in-situ pours, where the added adhesion is beneficial on vertical forms. CSE PRO is available in all the exposure depths indicated above and inclusion of ARCON Fluid in the mix design is recommended for optimum consistency at the surface.

NOTE: As a solvent based formulation CSE PRO is not stocked in the UK, but is available to order.

Surface Protection:
We recommend all exposed aggregate surfaces should be protected with an application of a penetrating dirt and stain resistant sealer. The Hebau Colorfresh Intensiv and Colortec Max products are specially formulated for this purpose and should form part of any good exposed aggregate specification.
