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.
