Application Instructions

Preparation

Foundation Surface

The surface of the substrate must be sound and free from oil, grease or any loosely adherent material. Bolt holes and fixing pockets must be blown clean of any dirt or debris. To assist in the formation of bond between substrate and grout, pre soaking of the substrate surface with water is advisable.

Base Plate

It is essential that this is clean and free from oil, grease or scale. Air pressure relief holes should be provided to allow venting of any isolated high spots.

Formwork

All formwork used for grouting should be leak proof. This can be achieved by sealing the joints/gap between formworks with a foam rubber strip or sealant.

Mixing Water

The quantity of clean water required to be added to a 25kg bag of Estogrout MP 50 to achieve the desired flowable consistency is 3.8 – 3.9 litres

Application

Estogrout MP 50 may be placed in thickness up to 50mm at one pour. For thicker sections above 100mm it is advisable to add in well-graded aggregates, size range between 3mm to 15mm. Quantities of aggregate added to the Estogrout MP 50 should not exceeded ratio of 1:1 by weight.

Curing

On completion of the grouting operation all exposed areas, which are not to be cut back, should be thoroughly cured. This should be done after the initial hardening of the grout by continuous application of water or by application of suitable curing compound such as Estocure Product Range.
