How to use DURO Natural Rust Preventive Primer No.
Iron and steel preparation: Remove rust completely.
Surface must be dry and free of separation agents, grease and
dust. Do not use any rust conversion products!
Coating format: Stir DURO Natural Rust Preventive Primer
No. 623 thoroughly before use. Apply base coat of DURO Natural Rust
Preventive Primer No. 623 thinned with 5 - 10 % SVALOS Thinner No.
222 with brush, roller, or spraying device. Sand in between with
220-grain sandpaper not earlier than 24 hours after application.
Apply a sparing, undiluted second coat of DURO No. 623. In exterior
areas, a subsequent treatment of the surface with VINDO Natural
Gloss Paint No. 629 must follow within a week. In interior areas
depending on the field of application, a final coat may be applied
of AIDU Natural Radiator Paint No. 624, CANTO Natural White Satin
Paint No. 625, CANTO Natural Matt Paint No. 692 or VINDO Natural
Gloss Paint No. 629.
Zinc preparation interior: A thorough cleaning of the
surface to ensure adhesion is necessary: e.g. create a solution of
5 liters of water, 1/4 liter of a 25 % solution of
ammonia with a tablespoon of a wetting agent ( such as a dish
washing detergent ), then scrub the surface with a corundum fleece
such as Scotch Brite, do not use steel wool or a wire brush under
any circumstances. A grey foam will develop after 10 minutes of
scrubbing, rinse off thoroughly with water. Wear rubber gloves
while mixing solution and scrubbing. Before treating with DURO, the
surface must be completely dry.
Coating format: Follow coating format as for iron and
steel above. Previously varnished zinc surfaces should not be
painted over with DURO Natural Rust Preventive Primer No. 623.
Important tips: The Color tone might vary from batch to
batch du to the raw materials used. DURO Natural Rust Preventive
Primer No. 623 contains little solvent, so it tends to develop a
skin. Before using, simply remove the skin and stir well. Apply
coating only to thoroughly de-rusted surfaces immediately after the
de-rusting procedure. Transfer unused portion of product into a
smaller container for storage.
