General No. of Coats
New/bare timber - 3 coats alone for a colourless finish
New/bare timber - 2 coats onto Cetol BL decor for a coloured finish
Conditions: Do not apply when air/substrate temperatures are below 8ºC or above 25ºC during application or drying periods. Protect from frost until dry. Failure to meet these requirements may adversely affect the drying, visual quality and durabilityof the finish. Ensure product is thoroughly stirred before and during application, otherwise sheen variations may be experienced.Cetol BL Unitop is supplied ready for use. Do not thin.
For best results use a good quality synthetic-fibre brush specifically designed for the application of water-borne products. Apply the product in a full flowing coat, laying off in the direction of the grain, using the minimum number of brushstrokes
required to produce an even finish. Avoid overbrushing, which creates brushmarks and will reduce the protection afforded.
This initial coat should satisfy the porosity/absorption of the timber. Carefully denib the first 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. Three coats of Cetol BL Decor should be applied, allowing a minimum of 5 hours drying time between coats or a two coat application onto a coloured coating such as Cetol BL Decor for protection.
Brushes should be cleaned immediately after use with warm, soapy water, and then rinsed thoroughly with clean water. If spilled Cetol BL Unitop may be reoved immediately while still wet using warm,soapy water
