- Applications
- Compatible Substrates & Surfaces
- Primary Applications
- Repairing concrete with cement based mortars
- Concrete overlays and toppings
- Interior or exterior use
- Repairs that will be frequently wet or submerged after curing
- Clean Up
Clean tools and equipment with soap and water immediately following use. Clean drips and over-spray with water while still wet. Dried EUCOWELD 2.0 may require mechanical abrasion for removal.
- Directions For Use
Surface Preparation
The concrete surface must be clean, dry and structurally sound. The substrate must also be free of all curing compounds, form release agents and any other contaminants, which may prevent the proper adhesion of EUCOWELD 2.0. When using EUCOWELD 2.0 to bond Euclid Chemical cementitious repair mortars. After surface preparation is complete, rinse thoroughly with potable water. Allow the concrete to dry before applying EUCOWELD 2.0.
Application
Stir EUCOWELD 2.0 thoroughly before use. Do not dilute. For hand application, dampen brushes or rollers before use and shake out excess water. For larger areas or faster applications, use airless spray equipment or an industrial pump-up sprayer with a fan tip nozzle. Hold spray nozzle 12 inches to 18 inches (30 cm to 46 cm) from the surface and apply EUCOWELD 2.0 using a cross coat technique consisting of a horizontal pass followed by a vertical pass. Extremely porous surfaces may require two coats of EUCOWELD 2.0.
EUCOWELD 2.0 may be allowed to dry before placing repair mortars, concrete, or toppings, or the repair materials may be placed in a “wet on wet” fashion, immediately after application of EUCOWELD 2.0. EUCOWELD 2.0 will dry in approximately two to three hours depending on the temperature and humidity. If more than 7 days pass between EUCOWELD 2.0 application and placement of the concrete, topping, or mortar, the surface must be abraded to remove the existing product, and EUCOWELD 2.0 must be re-applied. During the product’s open time, regardless of the length of time, the surface must be protected from dust, dirt, foot traffic, and any other sources of contamination or abrasion before application of the concrete, topping, or mortar. Any dust, dirt, or other contaminants will severely affect the bond strength of the concrete, topping, or mortar.
