Standards Compliance of Cementitious Adhesive

BS EN 1504
BS EN 998-1

Cementitious Adhesive, also known as Vetorep CR523, is a ready-to-use cementitious fairing coat that is changed by a single component polymer and just needs water added on location. Vetorep CR523 is a smooth paste that works well with host concrete to repair surface flaws up to a thickness of 3 mm when combined. To give Vetorep CR523 its distinct qualities, a combination of hydraulic cement, precisely chosen fine fillers, and special additives is used.

Storage & Shelf Life

Vetorep CR523 in its original unopened bag has a 12-month shelf life if kept out of the ground in a dry, shady, and temperature-controlled environment that isn’t warmer than 35ºC.

Surface Preparation

All surfaces should be clean, sound, and uncontaminated before the application of Vetorep CR523. Clean the prepared area thoroughly by using a brush and/or compressed air. Soak the prepared with water immediately before the application of Vetorep CR523.

Design Criteria

Vetorep CR523 cementitious fairing coat is designed for vertical and overhead use to infill honeycombing and voids up to 3 mm deep in the surface of concrete. It can also be applied as a render from a feather-edge up to 3 mm thick and as blowhole filler up to 10 mm deep and 3mm wide.

Mixing

To ensure proper mixing, use a mechanical power mixer or drill fitted with a suitable paddle. However, for small quantities, Vetorep CR523 can be hand mixed using the proper tools and bucket.

Pour 7 – 8.5 liter of fresh water into a clean container, then add the powder slowly to the water while mixing continuously with a low-speed mixer/drill (400 – 600 rpm). Continue mixing for 3 minutes until obtaining a uniform consistency. Leave the mixture for 5 – 10 minutes to mature and then remix for 30 – 60 seconds without adding further water.

To enhance the scratch resistance of Vetorep CR523, we advise adding Vetobond PB434. Consult your Saveto representative for further information.

Placing and Finishing

Apply Vetorep CR523 by using a steel trowel. Apply the mixed mortar to the prepared substrates up to a thickness of 3mm. Allow the applied mortar to stiffen before trowelling to a smooth finish.

Blowhole or bug holes might have a larger size, so to ensure the well filling and the right repair of the hole (if it is more the 5mm deep and wide), fill the cavities gradually.

Curing

Vetorep CR523 does not require curing in normal ambient conditions. In harsh weather conditions, such as high wind and temperatures, it is recommended to cure it with Vetobond AB432

Cleaning

Clean all tools immediately after application using fresh water. Clean hardened materials mechanically.

Packaging & Coverage

Stated consumption data are for general guidance. Actual consumption depends on the nature of substrate, method of application, and wastage.

Shelf Life & Storage

The original sealed bag of Vetorep CR523 has a shelf life of 12 months, provided it is stored clear of ground in a dry and shaded temperature-controlled place less than 35ºC.
