For repairing floors subject to vibration, movement, or impact. Virtually indestructible impact and crack resistant floor repairs.
Note: While great care is taken with the colour samples shown, no guarantee can be given that they represent exactly the colours offered.
Watco Concrex Flex has been specially formulated to resist cracking in areas where floors may be subject to movement, vibration, flexing or impact.
The two-part epoxy resin mortar has outstanding strength and durability and is modified with an epoxy resin blend that offers a degree of flexibility. This means that it is far less likely to crack or break under impact than a conventional floor repair mortar.
Watco Concrex Flex also has excellent chemical resistance and cures quickly to allow the floor to be put back into use. Heavy duty thin section floor repairs are so strong that they can be feather-edged.
Surfaces should be clean, dry, and free of all loose material. Wire brushing or sweeping is generally sufficient. Watco Bio-D degreaser can be used to remove grease and oil. If the surface is damp, it can be primed with Watco Tack Coat.
The resin content of Watco Concrex Flex is very high. This means that a primer is not usually required when filling holes in concrete floors or resurfacing rough or damaged concrete. Watco Tack Coat adhesive primer is recommended when using Concrex Flex as a thin section screed over smooth surfaces. It is also recommended when repairing intricate/high impact areas such as broken floor joint edges, and damaged step nosings.
Wear protective gloves.
The resin and the sand are already pre-blended and is supplied with bottles of curing agent, 4 x 100ml.
The curing agent is added to the sand/resin at point of use, and once mixed the mortar should be used within 15 - 30 minutes depending upon temperature.
If the entire pack of Watco Concrex Flex cannot be used within 30 minutes, it can be part mixed. To split a pack carefully halve the sand/resin (ideally measured by weight), and use half the number of curing agent bottles. Do not mix inside the plastic bucket. Tip the sand/resin into a mixing tray or on a board.
Shake the bottles of curing agent thoroughly until the liquid is a uniform grey.
Form the sand/resin into a mound and leave a small hole in the middle. Empty the curing agent into the hole, ensuring the bottles are completely drained.
Carefully mix the aggregate with the curing agent using a trowel until a smooth mortar is obtained, this will take several minutes. The more thorough the mixing, the ‘wetter’, smoother and more manageable the mix becomes. Alternatively, you can knead the mixture by hand wearing suitable gloves. It is important to mix thoroughly until you achieve a consistent colour.
A ‘Cretangle’ or suitable open pan mixer can be used to mix large quantities.
Trowel the mortar firmly into the repair and finish with a trowel or float. To get a good smooth finish, regularly wipe the surface of the trowel with a cloth dampened with white spirit.
Watco Concrex Flex is normally applied at 5mm - 50mm thick, but repairs can be feather-edged if most of the repair is at least 5mm thick.
For repairs deeper than 50mm apply in separate layers allowing 6 - 8 hours between layers, or use Concrex Deep Fill which can be applied at 15mm - 100mm thick in one layer.
Please contact us regarding applications not described here.
Do not apply to wet surfaces.
Watco Tack Coat should be used for application to damp surfaces before applying Watco Concrex Flex.
