{"product_id":"watco-concrex-vertical","title":"Watco Concrex Vertical","description":"\u003cp\u003eWatco Concrex Vertical is a lightweight epoxy repair mortar for damaged concrete and masonry faces. Its non-slump consistency helps it stay in place while you rebuild worn or broken surface profiles on pillars, sills, lintels, beams, render and stonework.\u003c\/p\u003e\u003cp\u003eAt around one third of the density of ordinary mortar, it is easier to handle on vertical surfaces. Use it for frost-spalled concrete and surface damage around exposed reinforcement, after the steel and substrate have been prepared correctly. The grey finish can be smoothed with a steel float to blend the repair into the surrounding face.\u003c\/p\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eConcrete and render must be dry, sound and at least four weeks old. Strip away previous coatings, contamination and loose material. Wire brush powdering concrete, and remove algae and contamination from stone.\u003c\/p\u003e\u003cp\u003eClean exposed rusty reinforcement, treat it with a suitable rust converter and primer, and allow that treatment to cure. \u003cstrong\u003e\u003ca href=\"\/products\/watco-tack-coat\"\u003eWatco Tack Coat\u003c\/a\u003e is required for all vertical applications.\u003c\/strong\u003e Follow the primer instructions and apply the mortar while the primer is tacky.\u003c\/p\u003e\u003ch3\u003eTechnical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePack size: 10kg; colour: grey.\u003c\/li\u003e\n\u003cli\u003eType: epoxy resin repair mortar with lightweight fillers.\u003c\/li\u003e\n\u003cli\u003eCoverage: approximately 2.4m² per pack at 5mm thick.\u003c\/li\u003e\n\u003cli\u003eFinish: smooth and impervious at suitable thickness.\u003c\/li\u003e\n\u003cli\u003eTypical cure: 3–6 hours at 15–30°C.\u003c\/li\u003e\n\u003cli\u003eWorking life: 30–60 minutes at 15–30°C, shorter in warmer conditions.\u003c\/li\u003e\n\u003cli\u003eTools: steel float or trowel.\u003c\/li\u003e\n\u003cli\u003eShelf life: 12 months unopened; protect from freezing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDirections for Use\u003c\/h3\u003e\u003cp\u003eKeep the material at 15–25°C for at least eight hours before use. Follow the pack's mixing sequence: tip the aggregate onto a mixing board, combine the liquid components thoroughly and work them into the aggregate. Mix until the colour is consistent, wearing suitable protective gloves.\u003c\/p\u003e\u003cp\u003ePress firmly onto the tacky primer and shape the repair with a trowel. Smooth with a steel float, occasionally wiping the blade with a cloth lightly dampened with white spirit. Protect from rain during curing. Clean tools before the mortar hardens.\u003c\/p\u003e\u003ch3\u003eLimitations\u003c\/h3\u003e\u003cp\u003eConcrex Vertical is for surface facing and filling, not structural repair or bonding. It has less impact resistance than standard Concrex and may not be impervious below 5mm thick. Do not steam clean or expose to temperatures above 60°C.\u003c\/p\u003e\u003cp\u003eAt 10°C and below, curing slows and can stop; use \u003ca href=\"\/products\/watco-concrex-vertical-cold-cure\"\u003eConcrex Vertical Cold Cure\u003c\/a\u003e for low-temperature work. Check the repair profile and depth against the technical sheet before application.\u003c\/p\u003e\u003ch3\u003eProduct FAQs\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes Concrex Vertical need priming?\u003c\/strong\u003e\u003cbr\u003eYes.
