Site Visit:
Prior to installation, arrange visit to project site with the authorized representative to inspect and certify that concrete surfaces are in acceptable condition.
Verification of Substrates:
Verify that concrete surfaces are sound and clean. Ensure that concrete surface has not been treated with wax based curing compounds and does not have residues from formwork release agents left on the surface as they can cause loss of adhesion. Steel trowel finished concrete must be wire brushed prior to tiling
Surface Preparation
All surfaces must be cleaned and free of oil, dust, paint, curing compound etc. Thoroughly damp all surfaces before starting and keep in a moist condition during placing.
Mixing
Damp the grout mixer with water prior to mixing the initial batch of Lanko Grout 180 ECO.
Ensure that the mixer is free of standing water. Add the pre-measured quantity of water. Slowly add the Lanko Grout 180 ECO, mixing continuously for at least 3 to 5 minutes until a homogeneous consistent grout is achieved.
Water Required
Application
Underplate:
4.5 – 5 litres/ bag for flowable consistency
3.0-3.2 litres/bag for pasty consistency
Check that the formwork is sealed against grout leakage and that a minimum hydrostatic head of
100mm can be maintained. Ensure sufficient material is available to complete the work and obtain a continuous fill. Pour from one side only to avoid air entrapment, keeping a head on the grout to promote flow.
Do not vibrate, but rods, straps and chains can be used to aid complete filling.
Preplaced Aggregate Grout:
Grout should be pumped or poured into place. Compressive strength development and ultimate strength of the concrete are reduced slightly compared with flowing grouts.

Grouting Large Volumes:
For grouting thickness greater than 75mm, the addition of clean well-graded 10mm aggregates is recommended to reduce temperature rise. Use a maximum of one part aggregate to 2.5 part of grout by weight. Conventional concrete pan mixers and pumps can be used for mixing and placement.
Curing
Immediately after finishing, exposed area are should be thoroughly cured with water or curing compound.

Manufacturer’s Warranty:
Manufacturer shall provide standard product warranty executed by authorized company official. Term of warranty shall be [specify term] years from the Date of Substantial
Completion.
Applicator’s Warranty:
Applicator shall warrant the tile installation against defects caused by faulty workmanship or materials for a period [specify term] years from the Date of Substantial
Completion. The warranty will cover the surfaces treated and will bind the applicator to repair, at the expense of the applicator, any and all leaks through the treated surfaces which are not due to structural weakness or other causes beyond applicator’s control such as fire, earthquake, tornado and hurricane. The warranty shall read as follows:
Warranty: The applicator warrants that, upon the completion of work, surfaces tiled with
Lanko Grout 180 ECO will be and will remain free from any defect, due workmanship or materials for a period of [specify term] years from Date of Substantial Completion. In the event of any defects occurring within the warranty period from such causes, the applicator shall, at his sole expense, repair, replace or otherwise correct such defective workmanship or materials. Applicator shall not be liable for consequential damages and applicator’s liability shall be limited to repair, replacement or corrected of defective workmanship or materials. Applicator shall have no responsibility with respect to defects caused by structural failure or movement of the structure, or any other causes beyond the applicator’s control.
