Application recommendations: on properly prepared background offering adequate keying, cast on or spray on up to 10 mm in one pass for floated finishes or 15 mm if a scratched finish is required. On waterproofed or smooth backgrounds spray or cast on a 1st bonding coat of about 3 mm adding 500 grams of SBR per bag of product. Straighten the work immediately after with an appropriate tool. Float (sponge, wooden or plastic) after 2-3 hours or more depending on weather conditions.
Not suitable for light weight cement blocks.
Do not work in temperatures below 5oC or above 30oC. Protect fresh mortar from rain, frost or strong drying wind. In hot weather, dampen the background adequately and cure the work by applying a light water mist several times for a period of 72 hours.
