Cemlevel 10

Description:

Cemix Cemlevel10 is a pump or hand applied self leveling cementitious underlay & topping designed for application thicknesses from 3mm - 30mm in one operation. It is used for toppings & floor underlays on concrete slabs in residential and commercial applications.

Typical Applications & Uses

  • Self-leveling underlay & topping to concrete slabs in residential & commercial applications.
  • Floor preparation underlay for vinyl, carpets, timber and epoxy overlays.
  • Houses, apartments, shops, offices, schools, hospitals, sports arenas etc.

Advantages:

  • One component.
  • 3mm - 30mm thickness applications.
  • Self - leveling.
  • Easy to apply.
  • Can be walked on in 2 hours.
  • Can be overlayed in 48 hours.
  • Shrinkage compensated.
  • High bond strength.
  • Good abrasion resistance.
  • Durable.
  • Flexible.
  • No casein or protein bearing additives therefore suitable for food or hospital areas.

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.

Mixing:

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.

Application:

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.

Curing:

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.
