    webercote smooth & EC - standard

    Preparation & Application


    If considered necessary, substrates should be primed with webercote primer. New surfaces should be clean, sound and dry. Concrete must be free of coating such as mould oil and any laitance should be removed, following which the surface can be primed with webercote primer. Old surfaces must also be clean, sound and dry. Glossy surfaces should be roughened to provide a key. Lichen, moss or fungal growth must be removed and the areas treated with weber CL150 in accordance with the instructions on the data sheet*.

    Chalky or friable surfaces, or previously decorated surfaces which are flaking, should be wire-brushed to remove loose materials and then stabilised by one coat of webercote primer.

    Static cracks up to 3 mm wide can be covered with webercote EC - ensure material is brushed well into crack. Wider cracks should be filled with webercem fairing coat and allowed to dry, then spanned with a fabric mesh such as mesh NT prior to coating.

    * Full data sheet available from weber on request


    It is recommended that the coating is well stirred prior to use. A two-coat application is required - apply by brush or long haired roller at a minimum of 400 μm wet film thickness per coat. webercote EC is designed as a thick coating material, do not brush or roller out, i.e. overspread. Allow to dry for at least 24 hours between coats. Nominal drying time approx. 4 hours at 20°C; full cure in 2 to 3 weeks. webercote EC should be applied when ambient or surface temperatures are above 4°C. Do not apply below 4°C or when frost is expected.


    webercote EC will require little maintenance. lt can be washed down using clean water with a soft bristle brush. Re-coating should not be necessary for approximately 10 years, but can be carried out after thorough cleaning of the coating.


    Clean brushes or roller in water immediately after use. lf they become clogged, soak in very hot water containing a mild detergent.
