Applications
UltraCrete M45 is a rapid strength bedding and repair mortar for use with all ironwork conforming to BS EN 124. The rapid set properties make it perfect for emergency concrete road repairs, the levelling of street ironwork, bedding of kerbs, coastal protection and tidal repair projects.
Technical
M45 is supplied pre-blended in 25kg bags or plastic containers and requires only the addition of water. The product can be used from 10mm-75mm in one pass, with greater depths possible using the layer-upon-layer method. M45 achieves exceptional bond strength without the use of a primer. The product can be bulked out with the addition of up to 30% hard stone clean aggregate. Please note that this will reduce the products strength gain and alter its performance characteristics.
Preparation
Surfaces should be free from any contamination of oil, grease, paint, etc. Remove all loose particles and work on a sound substrate. Pre-soak the area with clean water prior to application to aid bond. Remove ponded water before applying the product.
Further information about preparation and mixing can be found in the product data sheet.
