Sigmacrete Urp

SIGMACRETE URP (For Repairs & Rehabilitation)  Features/Advantages: Increases flexural and tensile strength . Compressive strength is comparable with concrete.Reduced shrinkage, water permeability. Good bonding between old & new concrete. High strength mortar with good resilience.Durable structural repairs, restoration & waterproofing . Improved abrasion resistant flooring . Simple to use as it is a single component. Cures to a hard, tough & wear resistant surface. Bonds (adheres) strongly to the most surface types. Can be applied to an uniform thickness coating on horizontal and vertical surfaces. Allows trapped water vapours to escape and prevents blistering and adhesion failures. Makes cement mortar or coating compact which prevents salt penetration into the concrete. It is unaffected by UV light and prevents fading of concrete. It acts as anti-corrosive for steel. SBR is highly durable even in continuous contact with water. It is resistant to water, dilute acids and alkali solutions. Non-flammable,Non-hazardous, Non-toxic. Resistant to fungus and micro-organism growth. Typical Applications: Waterproofing of building, toilets sunken portion basement. Waterproofing of water tanks and swimming pools. Repairing of concrete and masonry walls-internal, external & terrace roofs by                          cement mortars. Renovation and protection of concrete against corrosion and salt petre. As a bonding agent for old concrete to new concrete, industrial floor or floor duct nosing repair. Direction for use : a) Method : (1) On a clean & well prepared surface apply SIGMACRETE URP cement slurry (SIGMACRETE URP : Cement: 1 : 1 Part by weight). (2) Apply SIGMACRETE URP mortar by trowel to achieve uniform & smooth finish. Application of SIGMACRETE URP modified mortar should be very fast as it cures fast. (3) Moist cure for 24 hours & then allow it to cure b) Preparation of mortar : Cement                      1.00 Kg Sand                           2.50 Kg Water                          0.16 Kg SIGMACRETE URP   0.20 Kg Adjust quantity of water for workability if required. Do not add excess water. Increase the proportion of SIGMACRETE URP for more demanding situations. Structure Repair : (a) Remove all sealed / loose concrete to reach up to the concrete or reinforced structure and remove all loose dust by means of wire brush. b) Remove all dust particles by means of high jet water. c) Apply one coat of SIGMACRETE URP with cement (Ratio of SIGMACRETE URP : cement :: 1 :1 PBW) on cleaned reinforcement & allow to dry for 2 - 3 hrs. Coverage: 60 + 5 sq.ft. / Litre / coat d) Apply SIGMACRETE URP coat i.e. mixture of cement: SIGMACRETE URP (1:1 by PBW) on entire surface. Allow it to dry for 1-2 hrs. Coverage: 30 + 5 sq.ft. / lit / coat e) Now prepare polymer modified mortar as given below and apply it on entire concrete substrate at 10mm or 20mm thickness as required. Cement                      : 50 Kg Sand                          : 125 Kg Water                         : 8-10 Kg. SIGMACRETE URP  : 8-10 Kg. Apply above polymer mortar by hand pressing over tacky SIGMACRETE URP   f) Allow to cure above polymer mortar for one day.
