Product Details

Fosroc Renderoc SP40Shrinkage controlled, polymer modified, fibrereinforced cementitious repair mortar, specificallydesigned for sprayingUsesRenderoc SP40 is suitable for wet spraying and hand applicationin a wide variety of repair applications, and is particularlywell suited to vertical and overhead repairs. Typical applicationswould include, but not be limited to, the following Mass infill to large areas Repairs to irregular profiles Excellent for repairs to fire-damaged concrete Fast track repair programmes, where rapidapplication at high volume is required Single layer, high build applicationsAdvantages Cost effective - shrinkage control enables repairs to becompleted „right first time Very low rebound is an additionalcost benefit Enhanced durability - works in tandem with extremelylow permeability to prolong effective working life Compatibility - aligns performance closer than ever before,to that of host concrete User friendly - specifically developed to provide an easyto-apply product, suitable for local conditions Definable performance - positive benefits are easilydemonstrated via a single, simple measurementDescriptionRenderoc SP40 is supplied as a single component, ready touse blend of dry powders and fibres which requires only theaddition of clean water to produce a highly consistent, handand spray grade, repair mortar suitable for most structural andload bearing repairs.Technical supportFosroc offers a comprehensive technical support service tospecifiers end users and contractors. Fosroc is also able tooffer on-site technical assistance, an AutoCAD facility anddedicted specification assistance in locations all over the world.PropertiesThe following typical results were obtained at a water:powderratio of 0.18.Test method Typical resultDrying shrinkage to ASTM C 157-9328 days : <1000 microstrainFlexural strength : >7 N/mm2 at 28 days(BS 6319 Pt.3)Tensile strength : >2.5 N/mm2 at 28 days(BS 6319 Pt.7)Compressive strength : >20 Mpa at 1 dayhand application(BS 1881 Pt.1161) : >45 Mpa at 28 days(iterative result, basedupon spray application)Note 1: 70mm cubes, air cured @ 25°C.Design criteriaAttention to the basic design criteria given below should ensurethat the full benefits of this technology are achieved :(i) Recommended limits for a single Spray/Trowel/Handapplication are:Minimum applied thickness : 10 mmOverhead sections : up to 150 mm thick*Vertical sections : up to 200 mm thick*Surface area of a single repair : see ‘Note'NOTE : The restricting factor on surface area will be thepracticality of maintaining a continuous application* built in layers of 10mm(ii) In situations where a substrate/repair barrier is required,or enhanced bond strength/working time is required, or wherethe substrate is likely to be damp (e.g. seawalls, quays etc.),Nitobond EP epoxy bonding agent should be used.(iii) Water addition - between 4.25 & 4.5 litres per 25 kg bagUnder no circumstances should part bags be used or additionalwater be employed. Either of these two actions willadversely affect material performance, automatically invalidatingFosroc???s standard product guarantee.Instructions for useRenderoc SP40 should be mixed and applied in strict accordancewith the Product Method Statement, a copy of which maybe obtained from your nearest Fosroc office.
