Teknos Helo is a fast drying solvent based varnish with good resistance properties. This varnish is suitable for varnishing all demanding woodwork indoors and outdoors. Available in 15%, 40% and 90% gloss levels.
Teknos Helo produces a varnish film which is hard and at the same time elastic and thus withstands abrasion and impacts. Detergents, grease or oil do not damage it. Examples of uses are wooden plank floors, furniture and other wooden surfaces whenever a durable varnish coat is desired.
Clean the surfaces from grease and dirt. Wash varnished surfaces with Teknos Rensa Super paint cleaner. Matt down old, intact varnish coats. If the old varnish coat is brittle or flaking, it is removed by scraper and paint remover. Cautious burning off can also be used. Thereafter the surface is sanded and sanding dust is carefully removed. Objects that are intended for outdoor use are before the varnishing primed with clear Teknos Woodex Base priming oil. Sand the surface again before varnishing and remove the dust.
Before use stir the varnish thoroughly down to the bottom of the can. Use always full gloss Teknos Helo 90 for priming and thin it by adding about 20% Teknos Teknosolv 1621. Sand lightly and remove the dust before the top coating. Top coat with undiluted Teknos Helo 15 by applying 1 – 3 coats. Sand lightly and remove the dust between all varnish coats. Apply the varnish with a broad varnish brush. There must be good ventilation during the application and the drying period of the varnish. For outdoor use we recommend tinted varnish.
The surface to be varnished has to be dry. During the varnishing and drying period the temperature of the ambient air, the surface and the varnish shall be above +10 °C and the relative air humidity below 80 %.
The varnished surface reaches its final hardness and washability within 3 – 4 weeks. Rough handling and washing is to be avoided during this period. Stained surfaces can be cleaned with a moist cleaning cloth or mop. Use a neutral detergent. Very dirty surfaces can later be cleaned with a slightly alkaline universal washing detergent.
