Conditions: Do not apply if there is a risk of rain, or when air/substrate temperatures are below 5ºC or above 30ºC during application or drying periods. Protect from frost and rain until dry.Failure to meet these requirements may adversely affect the drying, visual quality and durability of the finish.
Initial procedure Ensure product is thoroughly stirred before and during application, otherwise sheen and colour variations may be experienced.
It should not be necessary to thin Rubbol AZ plus. Excessive thinning will reduce opacity, and a third coat may be required.
Applying the product: For best results use a good quality, long-haired, soft bristle brush.
Two coats of Rubbol AZ plus should be applied, allowing a minimum of 18 hours drying time between coats. On new work, where practical, the first coat should be applied all round prior to fixing. Pay special attention to any areas of exposed end grain, tops and bottoms of doors, and undersides of cills. The second coat should be applied to all exposed surfaces, as soon as possible after the first coat has dried, but no sooner than 18 hours and within 48 hours, in order to provide full protection. In any event this period
should not extend beyond three months, otherwise additional preparation and coating may be necessary. If applied to exterior wood and the contract is of long duration, it is suggested that a further coat be applied prior to hand over to make good any weathering during the construction period. If the second coat is not applied within 48 hours, light sanding with a medium grade abrasive, to provide a surface “key” will be required. Ensure all dust is removed.The product should be applied in a full flowing coat, laying off in the direction of the grain, using the minimum number of brushstrokes necessary to produce an acceptable finish. Avoid overbrushing, as this will reduce the protection afforded. Apply to a minimum wet film thickness of 70 micrometres
