Application steps

MIXING

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

APPLICATION

Rollers

Product may be applied by short to medium 1/4–3/8 in. pile synthetic rollers. Two coats are recommended. Rollers are also used during reinforcement embedment.

             
Brushes

A wide soft nylon or bristle brush, Two coats are recommended, ideally product is applied with second coat at 90° to first.

               
Spray Equipment

Most types of industrial airless spray equipment e.g. GRACO ULTRA are suitable, pressure 3,000 p.s.i. tip size .11 to .15 and 60° fan angle. Although the product is designed with built in flow, the finer tip sizes provide the smoothest finish.

                   

Tooling & Finishing

Note: All reinforcements using Flexitape and Reemat GFM must use Sikagard 203 W as the Finishing base coat.

CLEANING OF TOOLS

Clean brushes and spray equipment with water. Dried Sikagard®-307 W can be removed with paint stripper, cellulose thinners, xylene or toluene. Use personal protective equipment (chemical resistant gloves/ goggles/clothing). Without direct contact, sweep up spilled or excess product and place in suitable sealed container.
