Preparation

Surfaces to be treated with webercote primer must be clean, dry and free from moss, lichen, fungal growth, oil, grease or loose material. 

In addition, new and old concrete surfaces should be free from curing agents and mould release oils. 

Existing coatings and painted surfaces must be checked for integrity and adhesion. A bond test should be carried out to assess suitability of existing coating for priming and overcoating.

Glossy surfaces should be roughened to provide a key.

Remove moss, fungal growth and lichen using weber CL150 in accordance with the instructions on the packaging and datasheet.

Laitance or chalky, friable or flaking decorated surfaces should be removed by wire brushing.

Application

One liberal coat is normally adequate as a foundation for subsequent decoration. Two coats may be applied if used as a surface sealed finish. 

webercote primer should be applied to refusal using a brush, short haired roller or spray, allowing to dry before any further applications or decorative coatings are applied. Drying times depend on surface porosity and temperature, typically 4 - 6 hours at 20°C. 

Do not apply when it is raining as webercote primer is water based and will be washed away. If rain occurs after an hour from application, little damage will occur under normal drying conditions. 

webercote primer can be applied in a confined space, but ventilation is required to ensure proper drying. 

Do not apply webercote primer if the temperature is below 4°C on a falling thermometer.
