Applications
UltraCrete M90 is an all purpose fast set mortar ideal for bedding ironwork and general repairs. The product is suitable for use on all ironwork conforming to BS EN 124.
Technical
M90 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. M90 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 on preparation and mixing can be found on the technical data sheet.
