{"product_id":"watco-tack-coat-sub-zero","title":"Watco Tack Coat Sub Zero","description":"\u003cp\u003e\u003cstrong\u003eWatco Tack Coat Sub Zero\u003c\/strong\u003e is a two-part \u003cstrong\u003epolyaspartic adhesive primer\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003eUse 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 \u003cstrong\u003e−20°C\u003c\/strong\u003e. Its low-temperature application range gives maintenance teams a way to plan repairs through winter and in refrigerated areas.\u003c\/p\u003e\n\u003cp\u003eUnlike 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. \u003cstrong\u003eConcrex Sub Zero can be placed directly onto the wet primer\u003c\/strong\u003e, so there is no need to wait for the initial tack to develop before applying that mortar.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eRemove 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.\u003c\/p\u003e\n\u003ch3\u003eTechnical Data\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e750ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComposition\u003c\/th\u003e\n\u003ctd\u003eTwo-part polyaspartic resin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUse\u003c\/th\u003e\n\u003ctd\u003eInterior and exterior\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCoverage\u003c\/th\u003e\n\u003ctd\u003eApproximately 3m² per pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCoats \/ Tools\u003c\/th\u003e\n\u003ctd\u003eOne thin coat \/ brush\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication range\u003c\/th\u003e\n\u003ctd\u003eDry floor above −20°C; application up to 30°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWorking life\u003c\/th\u003e\n\u003ctd\u003e20–25 minutes at 15°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTacky window\u003c\/th\u003e\n\u003ctd\u003eAt least 3 hours between −20°C and 10°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShelf life\u003c\/th\u003e\n\u003ctd\u003e12 months, unopened\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eDirections for Use\u003c\/h3\u003e\u003cp\u003eCondition and mix between 10–25°C.
