Conditions: Do not apply if there is a risk of rain, or when air/substrate temperatures are below 8ºC or above 25ºC 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.
After applying one coat allow a minimum of 6 hours drying time before overcoating. On new work, where practical the first coat should be applied all round prior to fixing. Pay special attention to exposed end grain, tops and bottoms of doors, and undersides of cills. Where appropriate (e.g. windows and doors), carefully denib the coat using a fine grade nylon abrasive pad or a fine grade (P240 or finer) wet or dry silicon carbide abrasive paper. Remove all dust.
Subsequent coatings should be applied as soon as possible after the previous coat has dried, but no sooner than 6 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.Ensure product is thoroughly stirred before and during application, otherwise sheen and colour variations may be experienced.Cetol BL Opaque is supplied ready for use. Do not thin.For best results use a use a good quality synthetic-fibre brush specifically designed for the application of water-borne products.Apply product in a full flowing coat, laying off in the direction of the grain. Use the minimum number of brushstrokes required for an acceptable finish. Avoid overbrushing, which creates brush marks and produces a poor quality finish.Coating system durability can be improved by use of end grain sealers.Cetol BL Opaque is a two-coat system on most surfaces, however when white or pale colours are being applied over a black or dark substrate, a third coat may be necessary.
Brushes should be cleaned immediately after use with warm, soapy water, and then rinsed thoroughly with clean water. If spilled,Cetol BL Opaque may be removed immediately while still wet,using warm,soapy water
