Watco Tack Coat Sub Zero is a two-part polyaspartic adhesive primer for low-temperature concrete repairs. Designed for use with Concrex Sub Zero, it provides a bonding coat for essential maintenance when cold conditions make a standard repair system unsuitable.
Use this cold-weather bonding primer for prepared floors, walls, ramps and steps, indoors or outdoors. It is suited to repair work in cold environments, including chiller rooms, and can be applied to a dry floor above −20°C. Its low-temperature application range gives maintenance teams a way to plan repairs through winter and in refrigerated areas.
Unlike the original Tack Coat, the Sub Zero version uses a polyaspartic resin formulation. Select it as part of the appropriate cold-weather repair system and follow the instructions for that version. Concrex Sub Zero can be placed directly onto the wet primer, so there is no need to wait for the initial tack to develop before applying that mortar.
The primer must remain wet or tacky while the repair is completed. It is supplied as resin and curing agent for mixing immediately before use, then applied sparingly with a brush. At very low temperatures it becomes thicker, which can reduce the area covered. Allow for the actual surface texture and site conditions when planning the quantity needed.
Surface Preparation
Remove contamination, loose material and ice. Degrease and allow the substrate to dry. Where working over an existing coating, remove poorly bonded paint and roughen sound paint to provide a key. Suitable substrates include concrete, render, stone, sand and cement.

Directions for Use
Condition and mix between 10–25°C. Stir each tin, combine the full contents and scrape the sides to include all material. Mix to an even consistency, one pack at a time. Apply sparingly. Place Concrex Sub Zero directly on the wet primer and complete the repair before the bonding coat hardens.
Limitations
Use on a dry, ice-free surface. Do not allow the primer to form a hard film before overlaying. Protect stored packs from frost. Read the Sub Zero sections of the technical sheet and both safety sheets before use.
Product FAQs
How cold can the application surface be?
The technical sheet specifies a dry floor above −20°C and application up to 30°C. Remove ice and prepare the substrate first.
Must I wait before adding Concrex Sub Zero?
No. Concrex Sub Zero can be applied directly to the wet primer. Complete the repair before the primer hardens.
How much area will a pack prime?
Approximately 3m² per 750ml pack. The primer thickens below 0°C, which may reduce coverage.
How long does it remain tacky?
At least three hours between −20°C and 10°C, according to the technical sheet. Plan the repair around the actual site conditions.
