EXP 2090

In-form retarder

Description

A unique series of in-form surface retarders used for obtaining architectural finishes on precast concrete. Tweleve etch-depths provide a full-range of finishes from a very-light acid-etch or sand blast, to traditional deep exposed aggregate finishes. Application rates vay by etch-dpeth from 350 to 500 ft2/gal (8.6 - 12.3 m2/L), see Table 1. No undercoat required and easy cleanup of formwork. A test panel simulating job conditions should be poured to confirm mix design produces desired etch.

The EXP series of products are designed for simulating a light acid-etch, or sandblast appearance to deep expsosed aggregate finishes on precast concrete. Table 1 – provides detailed information on etch-depth and coverage rates. The application rate of 350 - 500 ft² / gal. makes it a very economical product.

In-form surface retarders (IFSR) for simulating acid-etch or sandblast finishes, and creating exposed aggregate finishes.
