Ensure product is thoroughly stirred before and during application, otherwise sheen and colour variations may be experienced. Cetol Novatech is supplied ready for use. Do not thin.For best results use a good quality, long-haired, soft bristle brush. On new work, where practical, the initial 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 product should be applied in a full flowing coat (working well into joints and open grained timber, ensuring end grains
or sawn timbers are saturated with product). Excess surface material may be re-distributed after 5-20 minutes (depending on conditions), using the minimum number of strokes required to produce an even overall colour. This ensures that the first coat satisfies the porosity/absorption of the timber.
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.Allow a minimum of 12-24 hours drying time. Where appropriate (e.g. for joinery items such as windows and doors), the first coat should be carefully denibbed using a fine grade nylon abrasive pad or a fine grade (P240 or finer) wet or dry silicon carbide abrasive paper, in the direction of the grain. Do not break through the surface coating. Remove all dust.Subsequent coatings should be applied as soon as possible after the previous coat has dried, but no sooner than 12-24 hours,
in order to provide full protection. In any event this period should not extend beyond three months, otherwise additional
preparation and coats may be necessary. If applied to exterior timber and the contract is of long duration, it is suggested that a further coat be applied prior to handover to make good any weathering during the construction period.
These coats should be applied in a full flowing manner 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 60 micrometres
