MEP®. MUR FIN is a specially formulated grey cement based ceiling & concrete surface render for internal and external application.

MEP®. MUR FIN is a ready-to-use product that does not require the use of an adhesion primer.

USES

FEATURES AND BENEFITS

• Shuttered Concrete - concrete wall / ceiling / beams / Column
• Concrete blocks
• Natural stone
• Clean, sound, well adhered existing render
• Fiber cement board (using MEP®. PRIM GP as binder)

FINISHES

• Sponge finish
• Trowel Smoothed
• Fine Scraped

The float/sponge/trowel smoothed finishes produce inherent micro cracking on the render surface which may affect the aesthetical appearance but does not affect its durability

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 23.1 / 26.1 / 20.1
   ▪ Surface should be pre-wetted prior to application
   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 20 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)

   ▪ MEP®. MUR FIN is ready to use and does not require the use of an adhesion primer
   ▪ MEP®. MUR FIN should be applied directly on concrete surface by hand troweled or spray applied
   ▪ Ruled to a maximum thickness of 8mm per coat
   ▪ Wait for the mortar to set sufficiently before final profiling and finish to the desired effect

4. Reinforcement – Alkaline resistant fiber glass mesh

   Good practices _DTU 23.1
   - 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

5. LIMITATIONS

   Do not use on:
   ▪ Gypsum
   ▪ Paint
   ▪ Wood
   ▪ Weak mortar or plaster
   ▪ All type of metal: Steel, Aluminum…
   ▪ Other surfaces not mention in this tds

6. RECOMMANDATIONS

   ▪ 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
   ▪ 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 (optimization of the cure). Do not perform this operation in direct sunlight
   ▪ Do not apply more than 8 mm or less than 3 mm thick

7. PRACTICAL INFORMATIONS

   ▪ Packaging: 20kg triple-ply paper bags
   ▪ Handling and storage: 6 months if kept in a dry cool place in the original packaging
   In more extreme conditions this period might be shortened
   ▪ Tools: Mechanical mixer, Spray machine, trowel, sponge
