Priming and Surface Preparation

Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of dust, loose, flaking, friable material and substances that may diminish adhesion.


Surface imperfection should be repaired prior to coating to achieve a good result and desired finish. Surfaces may require patching, skimming or rendering using MaxiCrete [smooth patching & skimming compound], Maxipatch [polymer render], MaxiJoint (flexible jointing compound].

Good preparation is essential. Surface must be sound, stable, clean, dry and free of loose, friable and flaky matter and contaminants.
Cracks should be filled with a suitable filler and finished flush with the surface in accordance with good painting practice.

Prime surfaces with MaxiPrime at the rate of 6 to 8 sq.m. per litre (average of 90 sq.m. per 15 litre pail).  Allow to dry for about 4 hours in good drying conditions before applying MAXIFLEX.
Excessively porous surface may require an additional priming coat.


Stir product well before use. (Power stirrer).
Apply by brush, roller or spray in a minimum of two coats.
MAXIFLEX can also be used in conjunction with fibreglass reinforcing fabric to provide greater trafficability on horizontal surfaces.

Ambient temperature: Min. 10oC  Max. 35oC
Surface temperature: Min. 10oC  Max. 45oC
Do not apply product if rain or frost is imminent or possible before the product has properly dried.

Application Experience
We recommend that the product is applied by person with the appropriate skills and experience for the type of product. The acceptability of the surface is the responsibility of the applicator.


The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique.


On average 22 to 30 sq. m per 15 Litre Pail but dependant on information above. 12 to 15 sq. m per 15 Litre Pail when applied by coarse textured roller. MAXIPRIME. Undiluted: 6 to 8 sq. m per Litre Diluted: +/- 14 sq. m with the addition of 30% clean water.


MAXIFLEX can be tinted to almost any colour. Whilst colour formulations are computer generated and care is taken to accurately colour match, batch to batch variations may occur. It is recommended that single lot orders are placed for the full project. A batch to batch tint-matching charge may be levied. Arrangements can be made for the piecemeal supply of product. Colours and particular batch to batch colour-matching should be checked prior to application. No responsibility will be accepted after the product has been used and/or applied. Product used for touch ups must be taken from the same batch of product used for the original coat. Colours produced from white and light bases are usually included in the price of the product. A premium may be charged for colours produced from deep and accent bases.


Colour Batches
Whilst care is taken to accurately colour match, batch to batch variations may occur for reasons which may be beyond our control. We strongly advise that project requirements are ordered in a single batch lot to avoid colour matching from batch to batch. Minimum quantities and tinting charges may apply.


Contractor Responsibility
It is the responsibility of the contractor or applicator to ensure that the colour is within specification prior to its application. The Company shall not be liable for any colour variations after the product has been applied. Further, the applicator should use product for touch-ups from the same batches used to do the original coats.
