This property demanded a range of different treatments on each different elevation.
Keim systems were utilised in combination, ranging from natural stone repair using Keim Restauro, Keim Universal render; suitable for covering mineral, organic and mixed substrates, Keim Soldalit Fixativ as base coat for strongly absorbent substrates and KEIM Contact Plus Grob used as a bonding bridge.
Finally coatings of finishing coats were applied resulting in a minimum 15 year warranty.
The front elevation render was unsightly and areas of embellishments were broken or missing. The gable elevation had been rendered with a lime render and the rear elevation were of original unpainted sand/cement.
The external elevations commanded three differing specifications –
1. Front Elevation
Front elevation showing cornices and mouldings
KEIM Restauro Top Stone Repair material was utilised to repair and replace existing cornices and mouldings.
The render panels were then “over-rendered” with KEIM Universal Render at 5mm thickness to equalise the surfaces followed by 2 coats KEIM Soldalit-ME mineral paint.
2. Gable Elevation
This had had been completely re-rendered in a lime render; the natural choice is to apply a mineral paint finish; 1 coat KEIM Soldalit Fixativ was applied to reduce the porosity of the substrate whilst maintaining its optimum moisture vapour permeability.
This was followed by 1 coat KEIM Contact Plus Grob, a high build mineral paint and a full coat of KEIM Soldalit-ME.
3. Rear Elevation
The rear elevations were of original unpainted sand/cement render; following repairs to the render, KEIM Algicid was applied to kill algae and fungal spores.
1 coat Contact Plus Grob was applied to equalise the surfaces prior to finishing coats of KEIM Soldalit-ME.
