MEP®. CREPI PRO is a one-coat weather resistant grey render for internal and external walls

MEP®. CREPI PRO is classified as a W2 render with a water absorption coefficient ≤ 0,1 kg/(m2·min0,5)

CE marking No 16-13431-2784


MEP®. CREPI PRO can be used as a grey coat finishing render or as a base coat for receiving a decorative finish: Tiling / Paint / textured finish…


MEP®. CREPI PRO is suitable to masonry and walls conforming to DTU 26.1 / 20.1 and constructed from the following:

  • Concrete blocks
  • Bricks
  • Concrete (using MEP®. PRIM Pro as a bonding agent)
  • Natural stone
  • Fine Scraped
  • Sponge or Trowel Smooth
  • Rustic textured - from tyrolean style to heavy roughcast effect
  • NB: For additional information on the finishes refer to the data sheet on Textured Finishes
  1. Surface preparation

    ▪ Ensure that surfaces to be rendered are clean, sound and free of dust, release agent, fungi and/or any material which may affect adhesion
    ▪ Remove all traces of plaster, paint, etc
    ▪ All unsound areas, flaky or peeling layers must be removed and repair
    ▪ Construction of the masonry must be compliant with DTU 26.1 / 20.1
    ▪ Day before the application - pre-wetted up to saturation point
    ▪ Day of application – surface should be moistened (not wet) prior to the application
    ▪ On concrete surface such as ceiling / beam / column…, first apply a 2mm coat of cement-based key-coat/primer MEP®. PRIM PRO
    Notes: New walls must be allowed to cure for minimum periods to ensure that movement does not affect the rendering

  2. Mixing

    Mixing ratio: 4.5 lts (+/- 0.5lts) water per 25 kg bag
    ▪ Gradually add the powder into the required water quantity while mixing to avoid lumps forming
    ▪ Mix thoroughly to a creamy consistency
    ▪ Allow mix to gel for 2-3 min and then remix before use
    NB: Never add more water to the mix. Should the mortar stiffen up due to delays in application then discard the product and mix a fresh batch

  3. Application (Suitable for machine or manual applications)

    For float smoothed finishes for receiving a painted or decorative finish.
    ▪ MEP®. CREPI PRO should be applied directly on concrete block or “primed” concrete surface by hand troweled or spray applied
    ▪ Level, ruled and lined to a maximum thickness of 15mm
    ▪ Wait for the mortar to set sufficiently before final profiling and finish using a trowel, wooden, plastic or sponge float according to the desired effect
    For base coat finished for receiving tiling
    ▪ Apply one level, ruled, lined and compact 15 mm thick coat. Give a rough finish to optimize mechanical bonding

  4. Reinforcement – Alkaline resistant fiber glass mesh

    Where the block wall joins the slabs, columns, or lintels in door and window frames, particular points are formed in the façade, where stress from the works builds up. Consequently, they must be treated appropriately to prevent the one coat render cracking
    - At the junction between masonry and chaining, lay a strip of MEP.TRAM reinforce mesh suitable for this use overflowing 15 cm above the floor and 15 cm below the 1st joint of the underlying masonry
    - At the junction between different materials, bridge with an overflow of 15 cm on both sides
    - 50 x 30 cm mesh must be laid in the corners of the door and window frames
    - Good practices _DTU 26.1 / DTU 20.1


    Do not use on:
    ▪ Gypsum
    ▪ Paint
    ▪ Wood
    ▪ Weak mortar or plaster
    ▪ All type of metal : steel, aluminum …
    ▪ Other surface not mention in tds


    ▪ Do not apply in wet weather, or in temperatures below 5ºC or over 35ºC
    ▪ Dampen the surface prior to application
    ▪ Avoid application under a full sun or on a very hot surface. This can cause shrinkage cracks and/or the loss of mechanical strength in the one coat mortar applied
    ▪ To prevent it from drying too quickly in windy condition, it is preferable to protect the surface receiving direct dry warm winds
    ▪ Optimization of the curing - The day after the application, it is possible to moisten the plaster from the bottom up with a jet set in fog to rehydrate it. Do not perform this operation in direct sunlight
    ▪ Do not apply more than 15 mm or less than 3 mm thick
