Application

When applying the MR1 Monocouche system, firstly apply EcoRend K11 Key Coat Primer at approx. 3 mm thick and brush key, then apply MR1 Monocouche in 2 passes to a total thickness of 15mm.

When applying an SR15 Silicone Thin Coat Render system, apply EcoRend X32 Basecoat at 10mm thick with mesh then apply SP15 Thin Coat Primer then SR15 Thin coat render finish.

Yes, you can. If finishing with MR1, always ensure the base coat has been brush keyed.

If finishing with SR15 Silicone Thin Coat Render, always ensure the base coat has been sponge float finished.

You can but it’s not best practice.

Apply OCR at 5-8 mm thick with fibre mesh and brush key, then follow with 12 mm of MR1 Monocouche and scraped back to 10mm.

If work is interrupted due to weather or unforeseen circumstances, then generally speaking the base coat can be left a couple of days before applying the 2nd pass. However, if the base coat looks really dry then dampen the surface down before applying the 2nd pass.

There is no set time as it is dependent on weather conditions, however, the base coat will go from dark grey to light grey, so when you can see a difference and there are no damp patches you can begin priming.

This is weather dependent, on a warm day after a couple of hours the primer should be dry enough to render onto however on a colder day it could be longer. The best advice is when the primer is touch-dry then it’s ready to render onto.

  • Scratched finish
  • Roughcast finish
  • Sponge float finish (not a typical finish)

The finish for SR15 is dependent on application:

  • Hand applied gives a smoother finish
  • Spray applied provides more texture

EcoRend S10 Bonding Primer is designed to be used on masonry substrates prior to a render system in order to offer the following benefits:

  1. Using the primer will control suction rates which in turn ensures an equal drying rate of the render system therefore supporting colour consistency.
  2. The primer is also used to promote good adhesion of the system to the substrate.

Either process is acceptable and seen as best practice in accordance to our application guides.

This generally depends on the contractors’ preference, however in some instances it may be best to do one over the other, (may not have the option to mechanically fix the beads in place for example).
