Packaging

Easy, affordable, stylish

Celomix comes as a dry powder in bags of 1, 3, 5 and 10 kg. The colour code, production date and batch number are printed on every bag.

  • Acoustic
  • Thermal
  • Fire-retardant
  • Non-toxic

Which pack for your job?

  • 1 kgAbout 3 m²Local repairs, details and small decorative motifs
  • 3 kgAbout 9 m²One feature wall, such as behind a bed or a TV wall
  • 5 kgAbout 15 m²The walls of a small room or a hallway
  • 10 kgAbout 30 m²Large rooms, halls and projects

Coverage is based on about 3 m² per kilogram on a smooth surface, and about 2.5 m² on rough surfaces. For each wall or project, order the whole quantity at once and from one batch so the colour stays exactly the same. Work out the exact quantity

You will need

  • A pack of Celomix
  • A plastic bucket
  • A plastic trowel
  • Warm water

Application

Five steps to a finished wall

  1. Preparing the surface

    The surface must be dry, clean and free of dust; metal parts are covered with anti-rust paint and the surface is evened out with a primer of matching colour.

  2. Mixing

    Put the contents of the pack into a plastic bucket and add the amount of warm water shown on the bag; use 50 to 75% of it for the first mix and knead thoroughly.

  3. Resting

    Leave the mixture for 20 to 25 minutes, then mix again before applying.

  4. Trowelling

    The paste is spread and smoothed on the wall with a plastic trowel to an even thickness; each wall should be done in one go, without a break.

  5. Drying

    Depending on the weather and ventilation it dries in 8 to 24 hours, after which the surface is ready for use.

The exact amount of water for each pack size is printed on the bag.

For project managers, consultants and clients

Time, cost and quality, all under control

Applying with a single flexible trowel standardises the coating process and clears the usual bottlenecks in handing over the finishing phase.

Controlled consumption

Keeping to the standard nominal thickness holds the consumption per square metre to the approved budget.

Less waste

Leftover paste can be dried and soaked again, with almost nothing lost.

Schedule control

A trained applicator covers more area per shift, shortening the critical path of the finishing phase.

Handover without rework

Local repair instead of re-application, so the handover to the client is not delayed.
