Ronacrete’s Ronascreed DPM and Ronascreed mortar have been specified in a project to expand the waiting area inside Oldham Magistrates Court. Reasons for the Ronascreed specification by the contractor include fast curing properties and suitability for exterior use.

The project required the removal of the internal lobby, which would provide the extra waiting room space. A new lobby would then be constructed outside the building to provide a new court entrance.

A screed had to be laid to an area of 50m², which would raise the floor level up to that of the building’s interior. The new lobby would then be built upon this solid base.

The screed needed to be suitable for exterior application as it would be open to the weather until the new lobby was complete. Rapid curing was another key requirement so the entrance could be used the following morning by court visitors.

Ronascreed DPM and Ronascreed mortar from Ronacrete were selected to meet the application requirements.

Surface treatment process

  • Contractor Foggs Floor prepared the surface of the concrete slab by vacuum shot blasting to ensure it was lightly textured and free from laitance. Loose shot was removed and the surface was pre-wetted with clean water.
  • Ronascreed DPM was mixed using a slow-speed drill fitted with a helical paddle attachment. All the gauging liquid was poured into a mixing vessel and the powder component was slowly added to form a lump-free, creamy slurry. Two coats of the DPM were applied to the damp surface by roller. Each coat was allowed to dry before the next application.
  • Ronacrete rapid primer was then applied to the surface immediately before application of Ronascreed mortar. The primer was mixed thoroughly and applied evenly over the surface ensuring total and uniform coverage.
  • The Ronascreed mortar was mixed in a forced action mixer and placed onto the tacky primer, compacted, ruled and closed with a float.
