SURFA-ETCH® 108 – Surface Etching Solution for Improved Coating Adhesion

SURFA-ETCH® 108 is a non-flammable etching solution designed to prepare smooth concrete, masonry, galvanized steel, and aluminium surfaces before applying coatings. It improves adhesion, neutralizes alkaline salts, and effectively removes “white rust” from metal surfaces. With no objectionable odour or fumes, it is safe and easy to use in various indoor and outdoor applications.

Key Features:

• Improves Coating Adhesion – Prepares surfaces for long-lasting coatings
• Neutralizes Alkaline Salts – Prevents coating failure
• Removes White Rust – Ideal for metal surface preparation
• Non-Flammable – Safe to use in various environments
• Odour & Fume-Free – Comfortable and safe application

Directions for Use

To ensure homogeneity shake well before use. Scrape or sweep away grease, oil, dirt and
all other surface contaminations as much as possible. Degrease by means of alkaline
cleaning, high pressure (steam) cleaning or, for small patches, by volatile solvent cleaning.
Apply Surfa-Etch 108 Etching Solution liberally and scrub it into the surface. Allow to stand
for 10-15 minutes, depending on temperature, and clean thoroughly by flushing with plenty of fresh water. Do not allow the Surfa-Etch 108 Etching Solution to dry before rinsing. Concrete and masonry may need a second treatment. After cleaning, remove any
remaining water and allow to dry completely, as moisture left on the surface or entrapped
into pores may cause failure of the coating system. Large surface areas or poor drying
