ARDEX BG 40 GP is a ready to use cementitious non-shrink grout to suit various purposes. It is nonmetallic and chloride-free. It requires addition of water to 

The product is specially formulated to create a non-shrink, non-metallic, chloride and nitrate free grout. Small amount of water is mixed to ensure early strength and long term durability. The selected composition of silica sand enables homogeneous blending and minimizes separation.


Bedding bearing plates

Precast applications: bedding precast units (walls, slabs, refuse chutes) and filling of precast joints and gaps

Small patch repairs


Premixed cementitious grout, economical and easy to use

Shrinkage compensated

Non-corrosive, no corrosion to rebar, staining or deterioration due to rust expansion

Chloride-free composition allows high early strength development without the use of chlorides

LOCATION: Internal and external applications


13.5 m2 (flowable consistency)

12.0 m2 (trowelable consistency)



For horizontal application, apply well-mixed ARDEX BG 40 GP to the prepared surface at a thickness of 10 mm to 40 mm in one layer. For vertical applications, reduce the ratio of water to a drier consistency.

For placement of more than 1 layer, the surface of the intermediate layer should be scratch-keyed prior to the application of subsequent layers. Application of the next layer may proceed as soon as the previous layer has fully set. Consistent with cementitious toppings, it is essential to allow ARDEX BG 40 GP to cure naturallly in ambient conditions.

Protect ARDEX BG 40 GP against rapid drying due to strong wind and direct sunlight or high temperature by covering it with poletylene sheet, or wet hessian.


Place specific amount of water into a clean container. Slowly add the contents of ARDEX BG 40 GP (powder) and mix with a slow speed drill fitted with a paddle type mixer blade of approx. 3−5 minutes until a homogenous and lump-free consistency is achieved.


Semi Precast (Trowelable): Approx. 12.5 litres/25 kg when mixing with water volume of 3.3−3.5 litres.

Flowable: Approx. 13.5 litres/25 kg when mixing with water volume of 4.25−4.5 litres.
