Stonex Sand

Stonex sand consists of fine quartz combined with an epoxy binder. These surface are extremely hard and ideal for heavy industrial use.

Overview

A stonex sand floor is comprised of millions grains of coloured sand that was processed for millions of years on river beds by erosion. This grains are coloured and sieved to produce a high quality, very fine aggregate.

The grains are then combined with an epoxy binding agent, trowelled into place before being pore filled with another epoxy and finally sealed with a polyurethane sealing coat.

The result is a very hard, wear resistant, seamless floor with infinite colour choices available.

Characteristic and benefits; hard wearing, colourful, non porous, chemical resistant, non slip (with additive)

Typical uses; Swimming pool surrounds, changing rooms,.commercial kitchens, nightclub floors,

Quartz Sand

Flexflooring source high quality quartz and can colour match or come up with unique coloured blends that will be bespoke to the individual or you can opt for some of our popular blends.

Binder

epoxyThe small granules of sand are combined with a low viscosity, colourless epoxy binder, mixed together before being trowelled into place. Epoxies are known to be very hard and resistant to various chemical and mechanical loadings.

Flexflooring source various different epoxies from around Europe.

Pore filling and sealing

Pore Fill

Once the Stonex sand floor has been laid and sufficiently cured (normally around 24 hours), the surface has to be pore filled with another epoxy substance, know as a thixotropic epoxy. This epoxy is forced into the surface filling all the microscopic pores that exist, making it a non porous surface. Normally two coats are applied to fill all the pores.

Once this has all cured, a final matt seal coat is normally applied. At this stage, an additive can be made to improve the non slip qualities of the surface, especially important in wet environments such as changing rooms.

Wet epoxyEpoxy surfaces do not like moisture, as this picture displays.

In this instance, water leaked from pipe work not long after the floor was installed and as can be seen the water reacted with the epoxy causing it to go a deep milky white.

The surface had to be cut out and re-installed.

It is therefore of vital importance that when these surfaces are installed it is bone dry with no chance of water ingress, while the Stonex sand is curing.

Description

Stonex Sand is 100% solids epoxy combined with a bespoke graded fine quartz. It provides a high build system that is impact resistant, can withstand chemical loading and is very durable. Otherwise known as an epoxy mortar.

Use

Stonex sand can be used to create a hard wearing, seamless surface, and can be used in industrial environments, where traffic is heavy, such as fork lifts etc

Preparation

Surfaces must be structurally sound, dry and degreased. The surface must be of sufficient texture to allow the material to key. New concrete surfaces must be allowed to cure for at least 28 days. Test for moisture content before installation.

Mechanically abrade the surface to obtain textured finish, grinding / shot blasting etc.

Crack filling, infill or cracks with a suitable epoxy and tape.

Application

Prime the surface with a suitable epoxy primer and to improve the mechanical key further, broadcast sand into the primed surface.

Mix the Stonex Sand with the epoxy, with a binder ratio of 10%, apply to the surface with a metal float.

Once cured, use a squeegee, to force in a thixotropic epoxy gel to pore fill. Allow to cure and apply again.

Finishing coats

Once cured, apply a PU matt coat evenly with a roller.
