Substrate Preparation:

Concrete substrates should be sound & roughened to ensure a good bond. They should be uncoated & clean, free from all contaminants, loose particles, dirt, oil, mould, curing compounds, sealers & paints etc. Acid washing, rough honing or scabbling & then water blasting or vacuuming may be required to prepare the surface depending on substrate condition. Washing with soap & water blasting may also be required if oil is present. Cracks should be repaired with a suitable Cemix repair product. The better the substrate preparation & condition the better the end result. The concrete substrate should ideally be at least 1 month old.

Movement / Control Joints:

Honour any control joints in the concrete substrate – do not apply product over control joints. Mimic control joints in concrete substrate up into the topping. Install suitable control joints in topping if required.


Mix whole bags of product. Add 4L of water to mixer & then add product to water. Add rest of water slowly whilst mixing until the desired consistency is achieved. Maximum total water is approximately 5 to 5.5L per 25kg bag. Mix thoroughly for 2 to 3 minutes using a drill & paddle or mechanical mortar mixer. Do not mix more product than can be mixed, placed & finished in 30 minutes.


Dampen the concrete substrate & then prime it with Cemix® Multibond brushed undiluted into the surface just prior to mortar application. Apply the Cemix® Cemlevel10 on to the Cemix® Multibond primer before the primer dries completely. The ideal application timing is when the Cemix® Multibond is still tacky, but not dry. Pouring & leveling should take place in one operation. Cemix® Cemlevel10 can be used from 3mm to 30mm in depth. The freshly poured material can be gently worked to release any air bubbles etc. Trowel finish the semi-hardened surface as required.

Floor Tolerances:

A level survey of the existing surface is recommended prior to the application of Cemix® Cemlevel10. In order to achieve the required tolerance, large deviations in the existing surface should be pre-leveled prior to the application of Cemix® Cemlevel10.


Prevent early plastic state moisture loss prior to the product setting. Where possible, cure product thoroughly after it has set by keeping it wet & covered for at least 3 to 7 days. Can be walked on in 2 hours under normal conditions. Can be overlayed in 48 hours under normal conditions. Avoid product freezing for at least 2 days. Avoid dehumidifiers for at least 2 days.
