In-Form Retarder for Exposed Aggregate and Construction Joints

Vertical ETch Retarder is a ready to use, water based red liquid which reveals aggregate in fresh concrete by delaying the surface set, so that the mortar paste may be brushed and washed from between the aggregate particles to produce an attractive exposed finish. Used anywhere you desire an exposed aggregate finish on vertical surfaces such as steps, walls, pre-casts, decorative concrete work. Also used for preparing concrete construction joints for better bonding.
TECHNICAL DATA
Appearance - Red liquid.
Specific gravity - 0.98.
Viscosity - Sprayable with normal spray equipment.
Vertical ETch Retarder is Non staining, Fast Drying, Non corrosive, Non flammable. safe and easy to use. With guaranteed results.
Vertical ETch Retarder will retard the set of the surface cement normally 12 - 24 hours when applied as directed. The setting time will be influenced by air temperature, cement type, content and slump. If the surface is not washed off within 24-48 hours the surface concrete will set and reach full strength. A trial run is recommended before general application to determine timing and the depth of etch required.
INSTRUCTIONS FOR USE
Agitate Retarder thoroughly before use. Be sure all form materials are dry and clear of debris. Using a low pressure sprayer, spray affected areas of formwork to be exposed. It is important that formwork does not get wet after being applied. Vertical ETch has been designed to be fast drying and will dry into most form surfaces within 20 minutes. Including plywood, dura-forms, soft or hardwoods. Vertical ETch has been formulated to be easy to use, with excellent results every time. Vertical ETch is totally environmentally friendly. Place concrete in formwork (3 parts cement, 4 parts sand, 6 parts aggregate by volume is a typical mix) Protect the coated surface from abrasion when placing concrete.. Within 12 - 24 hours after application remove form work and proceed to remove retarded vertical layer of mortar with a stiff broom and garden hose water, leaving a clean exposed aggregate surface. If extremely small aggregate is used, it is important not to start the wash off too early, as bare spots may be created.
