Application Advice

Intercromex application recommendations:

Preparation: add 4.5 to 5 litres of clean water per bag. Mix Between 3 and 5 minutes maximum. 

Protection and curing: do not apply in temperatures below 5oC and above 30oC. Dampen the background to control suction prior to application. Protect against drying wind, rain and strong sun. If necessary cure with light water mist for 2-3 days. Wait 7 days before applying a finishing coat.

If required, Intercromex can be floated to a finish and painted when dry. 

It is recommended that Intercromex is cast on or sprayed on. For work on metal lath apply Intercromex as a first coat of minimum 10mm (15mm max.). 

On precast cement blocks make sure that de-moulding oils are eliminated (if necessary by sanding or high pressure water jet). 

Monstastier application recommendations:

On properly prepared background offering adequate keying, cast on or spray on a minimum of 10 mm in one pass for floated finishes or a minimum of 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, porous 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. 

When Monostastier is applied as a finishing coat on a existing backing coat, the maximum thickness for floated finishes is 5-6mm or 6-8mm for scratched finishes.
