Surface Preparation
The surface must be solid, compact, clean, free from dust, cement laitance, oil, grease, etc. All loose parts of concrete should be removed. A coarse surface profile with aggregate exposed is preferred.
Saturate the support with water several hours prior to grouting. Concrete surface should be damped (with no free water) in order to avoid possible water absorption at the moment of casting.
Base plate must be clean and free from oil, grease, etc.
Formwork should be constructed to be leak proof as ESPOCEM GP is a free flowing grout. It should also include outlets for the pre-soaking water.
Mixing
To prepare the mortar, pour into a cement mixer or into a container about 3.0 – 3.5 Liters of clean water (depending on the required consistency), add 25kg bag of ESPOCEM GP and mix for few minutes using mixer or drill machine fitted with suitable paddle till obtaining a homogeneous mixture, free from lumps.
Do not add extra water to the mix more than what specified. If the mix starts to harden, do not use the mix, prepare a new one.
Application
The mixed grout should be poured only from one side of the formwork to eliminate the entrapment of air. This can be achieved by pouring the grout across the shortest distance. Maintain a constant hydrostatic hand, preferably of at least 15 cm on the side where the grout has been poured, allow 10 cm clearance between the side of the form and the base plate of the machine.
ESPOCEM GP can be placed in thicknesses up to 20 cm.
Curing
The repaired area shall be cured in accordance with good concrete curing practice and protected from drying winds. Curing shall be done with non-degradable curing compound BETOCURE AR. Alternately; a wet Hessian cloth covered with polyethylene sheet can also be employed.
Cleaning
ESPOCEM GP should be removed from tools and equipment and mixers with clean water immediately after use. Cured material should be removed mechanically.

ESPOCEM GP is a cement-based product.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
