Application Instructions


 

Substrate Preparation


All loose, flaking and unstable material must be identified and then thoroughly removed, all surfaces must be thoroughly washed down with clean cold water to remove all surface dirt and dust. When all surfaces are clean, sound, wind dry, dust free and free from all surface contaminants, decoration using KEIM Mineral Paints may proceed.

 

Application


KEIM Concretal Lasur will enable a colourwash appearance to be applied to the concrete; this can match the surface and be employed to minimise any surface variations or blemishes. The system will protect the concrete whilst still maintaining the feel and appearance of a concrete façade.

KEIM Concretal Lasur should be applied by brush and laid off with a lambs wool pile roller or by airless spray, it is important that a wet edge is kept at all times and that contractors work to a natural breakline.

A typical specification would be a two coat KEIM Concretal Lasur system; the first coat to be KEIM Concretal Dilution or Base applied by brush and worked well into all surfaces. After a minimum period of 12 hours a final coat of KEIM Concretal Lasur may be applied, diluted to the required level with KEIM Concretal Dilution or Base.

 

Application Conditions


Ambient and substrate temperature above 5°C and below 30°C. Do not apply in direct sunlight or onto sun-heated surfaces, nor if it is raining or if there is an immediate likelihood of rain.

 

Consumption


For a two-coat system, using a 3:1 dilution ratio on the second coat, approximately 0.025lt/m2 for KEIM Concretal Lasur and 0.075lt/m2 for KEIM Concretal Dilution.

Consumption rates are offered for guideline purposes only and are quoted for smooth rendered surfaces. Actual rates are the responsibility of the applicator. Project specifications should be referred to for specific rates.

 

Cleaning of Tools


Clean tools with water immediately after use.
