Fine Crack Repair Products
Concrete floors can be subject to small cracks and holes, which need to be smoothed out. A solvent-free two-part epoxy resin, Rust-Oleum Epoxyshield Fine Crack Repair Mortar is really easy to use and repairs fine cracks up to 3mm wide. Simply smooth over the cracks in you concrete floor and it will be dry and sound after four hours. Recoat after the four hours, leave it to dry and you’ll be left with an even, smooth and perfect surface.
204 Fine Crack Repair works in a similar way, but on cracks from 0.2mm up to 20mm. Also solvent free, Fine Crack Repair is an epoxy resin that can be used to fill small cracks, voids and craters in brickwork, concrete and masonry. It’s weather resistant, waterproof, high strength and very easy to use. This particular crack filling resin is recommended to use for filling joints and voids that aren’t subject to movement. It’s worth noting that once it’s mixed, it must be used immediately, so the area that needs to be repaired must be ready beforehand.
Sika Joint Repair Fillers
Sika Primer 3N is a solvent-based primer used beneath elastic adhesives and Sika joint sealants. It’s easy to apply with a paintbrush and provides improved bonding on porous substrates, such as concrete, ahead of applying Sikabond Adhesives.
For a Sika joint filler or sealant, have a look at Sikaflex Construction+, which is a flexible sealant for connection and movement joints in concrete and masonry building facades. Construction+ is great for resisting weathering and ageing, which will prolong the life of your façade and minimise the need for constant maintenance. It doesn’t cause much stress to the substrate and is guaranteed to stick well. Solvent free and odourless, it has the benefit of giving low environmental impact and also works well in tropical and hot climates.
Sikaflex AT Connection is an elastic joint sealant for the connection joints between non-porous and porous substrates so it’s perfect for sealing windows and doors. It’s silicone-free and can be easily painted over, lasts for ages and is simple and straightforward to apply. It can be cleaned with Sika Thinner C or Sika Remover 208.
Known by some as ‘foam boom’, Sika Boom GS is an expansive fixing foam. Applied with a gun Sika foam works well as a joint filler, thanks to its insulating, filling and fixing properties. It insulates really well against draughts and sound and is perfect to use around door and window frames, air-conditioning vents and roller blind fixings.
Flexible Joint Fillers
MMA Flexible Joint Filler is a flexible methacrylate sealant that is extremely tough. It’s hard enough to protect edges from heavy traffic and yet is able to retain a degree of flexibility, enabling it to last a long time. It has a high level of adhesion to concrete and is simple to clean, making it extremely hygienic.
A pourable joint filler for expansion joints, as well as other floor joints, Rust-Oleum 5160 Flexible Joint Filler can be used inside and outside. It remains flexible, which allows the floor to collapse and expand and it’s very fast acting – sealed joints can be walked and driven on after around 12 hours. We advise using 5161 Joint Primer to improve the adhesion of the filler.
