Nu EcoSafe Strip – Concrete Etch

Water-Based Surface Prep Etching Compound

Nu EcoSafe Strip Concrete Etch is a water-based surface prep etching compound specifically designed to provide a surface profile on green and mature concrete. Etching is often a pre-requisite for application of high performance paint/coating systems.

Nu EcoSafe Strip Concrete Etch typical uses

Nu EcoSafe Strip Concrete Etch, has been proven to effectively etch green and mature concrete and masonry. The depth of etching achieved with Nu EcoSafe Strip Concrete Etch is the same as that of hydrochloric or muriatic acid. The residue is easily removed by water rinsing. These products are suitable for treating vertical and horizontal surfaces.

Nu EcoSafe Strip Concrete Etch is suitable for the following projects:

  • Sidewalks
  • Patios
  • Shop floors
  • Factory and warehouse floors
  • Aircraft hanger floors
  • Residential garages
  • Driveways
  • Concrete stairways
  • Tilt slab walls.

Nu EcoSafe Strip Concrete Etch has the following qualities:

  • Fast acting
  • Will not burn skin on contact
  • No corrosive fumes like muriatic acid
  • Will not run or migrate
  • Clings to vertical and horizontal surfaces
  • Easy clean up with running water
  • Non ozone depleting
  • Water-based
  • Biodegradable
  • Non-flammable
  • Contains no TAPs or HAPs (Toxic/Hazardous Air Pollutants)
  • Will remove most concrete
  • No muriatic acid
  • Low odour

Additional Benefits that contribute to Cost effectiveness:

  • Reduces man-hours and effort required to complete a project
  • Reduces cost of waste disposal
  • Reduces down time since other work at site can continue while safe etching is being conducted
  • Lowers insurance costs for worker safety and storage hazards.

Applications & Features

Equipment & Tools

This product is engineered for brush or broom application. Other equipment: brushes, broom, plastic watering can, masking tape, polyethylene sheet, pressure washer, empty pails for clean-up, running water, rags.

Preparation

Ensure that all areas not to be etched are suitably protected. Ensure that all areas to be etched are clean, dry and free of oil and grease. Optimum surface temperatures should be in the range of 20° to 32°C. The product performs effectively at lower temperatures (even at 0°C) but the dwell time increases.

Test Patch

Conduct a small test on an inconspicuous area to ensure product performance. This will indicate the time required and dilution rate for project completion and suitability of product for the substrate.

Application Guidelines

Application Procedure

Pour product on area to be etched and spread using a nylon brush, broom or rag. Allow to dwell for 15 minutes. Agitate with a nylon brush or broom and allow to dwell for another 15 minutes. Most concrete will be etched within 30 minutes of exposure. Rinse or preferably high pressure clean the surface as soon as an adequate etch has been achieved.

Dwell Time

The time required to etch the concrete depends on the type and age of the concrete. Most concrete will be etched within 15 to 30 minutes. Rinse the product off as soon as an adequate etch has been achieved. If you want a deeper etch, apply fresh product and allow another 15 minutes of contact time. Repeat if additional etch is required.

Coverage

Depending on the substrate, the coverage rate normally falls between 2 to 3 sq.m/L.

Dilution

For rough stipple finish concrete, dilute 1 part to 10 parts water and for smooth steel troweled concrete, dilute 1 part to 5 parts water. For surfaced hardened concrete or high MPA concrete do not dilute. Always check concrete to ensure concrete has been etched and is porous. Repeat process if required.

Re-Coating

As with any etching compound, it is advisable to check the pH of the substrate before recoating to ensure that it is compatible with the new coating system to be applied

Removal & Clean Up

Be sure to use generous amounts of water. For small areas, removal of residue can be completed by wiping with a dry cotton cloth, followed by generous water rinse. For larger areas, best results are achieved using a pressure washer. It is important to remove all loosened concrete residue in the rinsing process. You can use a wet vacuum to remove the excess water to allow concrete to dry faster. Nu EcoSafe Strip Concrete Etch will remove rust on paint but will not affect the painted surface.

Safety Precautions

Proper safety procedures should be followed at all times while handling the product. Wear rubber gloves and safety goggles.
