Patch EverFlor FlowFix®

EverFlor FlowFix Patch is a concrete floor repair mortar for holes, spalls and localised damage in working floors. It is a reinforced, polymer-modified cement powder. Add clean water, mix and pour it straight into the prepared repair. There is no resin or hardener to weigh, and no primer to apply first.

The mixed material is a flowable mortar rather than a stiff, hand-packed one. It runs into irregular holes and broken edges under its own weight, so finishing is limited to a steel float or trowel where placement needs help. Place it at any depth from 5mm to 100mm in a single application.

FlowFix Patch is the standard repair product in the EverFlor FlowFix range. Use it for general holes and damaged concrete. For deeper or larger-volume repairs, use FlowFix Deep Patch, which is formulated for deeper sections.

Recommended areas of use

• Damaged concrete floors
• Warehouse and factory floors
• Loading bays and distribution centres
• Workshops and industrial premises
• Internal and external concrete surfaces
• Holes and voids filled prior to resurfacing

Features

• Single component: the powder needs only clean water, so there are no resin parts to measure or mismatch
• Flowable consistency fills irregular holes without packing, which cuts trowelling time
• Reinforced, polymer-modified cement gives a hard repair under foot and forklift traffic
• Rapid strength gain: above 20N/mm² at 1 day, above 35N/mm² at 7 days and above 45N/mm² at 28 days
• No primer required on prepared, sound concrete
• Interior and exterior use, with an operating range of -20°C to 70°C once cured
• Tools clean in warm soapy water before the mortar sets

Good to know

The working time is short. Mix beside the repair, and mix only what you can pour straight away. Do not add water beyond the stated ratio, and do not re-mix mortar that has started to stiffen.

Preparation decides the repair. The concrete must be sound, clean and free from loose material, oil and grease. Cut the edges of the repair square rather than feathering out, so the mortar sits at a working thickness right to its edge. Remove any standing water before you pour.

A flowable mortar finds its own level, so FlowFix Patch is not suited to repairs on sloping surfaces. Apply between 5°C and 30°C and protect the fresh repair from frost. Return-to-service times depend on temperature, repair depth and site conditions; cold sites and deep fills take longer.

SURFACE PREPARATION

The concrete must be structurally sound and clean. Remove all loose and friable material by mechanical preparation. Wire brush sound concrete to remove dust and laitance. Remove oil, grease and any other contamination that would stop the mortar bonding.

Cut the edges of the repair square to depth. Do not feather the mortar out to nothing in trafficked areas; a thin edge breaks away under wheels. Remove any standing water before you pour. No primer is required.

MIXING

Mix 25kg of FlowFix Patch with 8 litres of clean water. Mix 10kg FlowFix Patch with 3.3l of clean water. Put the water in the vessel first. Add the powder gradually while mixing with a slow-speed drill and paddle. Mix until the mortar is smooth, lump-free and pourable.

Pot life is 5-10 minutes at 20°C, and shorter in warm conditions. Mix beside the repair. Mix only what you can place at once. Do not add extra water to extend working time.

APPLICATION

Apply between 5°C and 30°C. Pour the mixed mortar straight into the prepared repair and let it flow into the hole. Use a steel float or trowel to level the surface where needed. Do not use FlowFix Patch on sloping surfaces; it will run to the low side.

CURING AND RETURN TO SERVICE

At 20°C the repair takes foot traffic after 30 minutes. Full cure takes 24 hours. Lower temperatures, deeper repairs and damp site conditions all extend these times. Protect the fresh repair from frost until it has cured. Clean tools in warm soapy water before the mortar sets.
