Water addition: 4 to 5 litres per bag of 20 kg.

Consumption: 1.7kg per mm of thickness per m2.

Shelf life: 12 months if kept in dry storage conditions.

Re-seal partly used bags.

 Application on clean and dry backgrounds where loose or friable parts have been removed:

 R100: Painted backgrounds (subject to paint being sound and well bonded), smooth concrete/cast concrete (free of demoulding oils),waterproofed surfaces, tiles, metal components (rust treated).

 R 50: all other backgrounds, including plasterboards, timber elements,bricks, stones,construction blocks, non waterproofed cement surfaces,gypsum plasters. On internal insulation panels, MDF, plywood, the application is permitted. Externally it is important that the insulation panels or other materials are not affected by humidity(dew point forming within the panel) causing in time a deformation of the panel and consequent movement. Please check with the manufacturers of the panels.

On COMPOSITE BACKGROUNDS: dress joints between different materials.Dub out, if necessary using Ecomortar R or, for large areas, NHL 3.5 mortar. If working on an NHL 3.5 dubbing out mortar, wait 1 week before applying Ecomortar R. Apply a 1st coat of about 3mm, bed in a fibreglass mesh. Apply a 2nd coat of 2-3mm.

 Waterproofing: in exterior applications, R100 and R50 require an effective waterproofing finish with

 Lime paint containing Uniprotect or suitable breathable mineral paints.

Alternatively it can be coated with a finishing coat of Ecomortar WP (5mm minimum), also available in a vast range of colours.

Precautions: do not apply in temperatures below 8oC or over 30oC. Protect work from adverse weather conditions until the finishing coat is applied and fully cured. In hot weather, cure with light water mist for the first 48 hours.

Observe current health and safety regulations.
