Sikagard®-203 W

Single component, waterborne, modified, acrylic resin surface coating

Sikagard®-203 W is a tough and highly durable single component waterborne acrylic, polymer intermediate and topcoat containing an organic in film preservative. Sikagard®-203 W has a vapor permeable structure which allows damp substrates to dry out without causing blistering or loss of adhesion. Sikagard®-203 W is available in white and 30 other standard colors.

Application steps

MIXING

Pre-mix material using a drill and jiffy blade (300–450 rpm).

APPLICATION

Rollers - Use short (3/8–1/2 in.) pile or sheepskin rollers for reinforcement embedment and for the application of primers on flat, low absorbency substrates.
Brushes - A wide, soft nylon or bristle paint brush, apply in 2 coats. Airless Spray - Most types of industrial spray equipment are suitable, use a tip size of 0.15 to 0.21. Two even coats are recommended. Use a nose/face mask when spraying.

CLEANING OF TOOLS

Clean brushes and spray equipment with water. Dried Sikagard®-203 W can be removed mechanically or with paint stripper. Use personal protective equipment (chemical resistant gloves/ goggles/clothing). Without direct contact, sweep up spilled or excess product and place in suitable sealed container. Dispose of excess product and container in accordance with applicable local, state, and federal regulations.
