PRODUCT DESCRIPTION;

An engineering quality fairing coat for filling minor blow holes and defects, and for repairing surface imperfections. Thin screed applications can be used to level both vertical and horizontal concrete surfaces to provide a fair faced finish. Monolevel FC is a single component, thixotropic, polymer modified, cementitious mortar with high adhesive properties, allowing it to be used as a thin screed, as well as a filler for filling minor voids and defects to provide a fair faced finish. It incorporates the most advanced micro-silica, fibre and polymer technology, curing to provide enhanced freeze/thaw resistance and protection from the ingress of water, acid gases and chlorides. The product is supplied as a single component system requiring only the addition of clean water.

PRODUCT ADVANTAGES;

Incorporates the latest proven cement chemistry, micro-silica, fibre and styrene acrylic copolymer technology.
Pre-packaged material requiring mixing with clean water on-site to give an adhesive mortar which can be rapidly applied in vertical and horizontal situations by brush, bag-rubbing, trowel or spray techniques.
High bond strength exceeds tensile strength of concrete, thus ensuring monolithic performance of the repair.
Dense matrix provides excellent protection from ingress of acid gases, moisture and chlorides.
Non-toxic when cured.
Economic mortar requiring no substrate or inter-layer priming.
Part bags can be mixed.
Suitable for feather edging.
Suitable as an exposed external finish without further protection or coating.
Easily over-coated with specialist membranes to provide further protection and aesthetic quality.

PACK SIZE;

25kg

YIELD;

15.5 litres from a 25kg pack

COLOUR;

Concrete grey or White

PRODUCT PREPARATION;

Mechanically remove all damaged concrete back to a sound core. The areas to be treated must be free from all unsound material, i.e. dust, oil, grease, corrosion by-products and organic growth. Smooth surfaces should be cleaned to remove release agents, curing compounds and surface laitance, preferably using wet grit or water blasting techniques or equivalent approved methods, and any steel cleaned to bright metal. The concrete sub-base should be a minimum of 20 MPa.

PRIMING;

The prepared substrate should be thoroughly soaked (preferably 24 hours before) with clean water until uniformly saturated without any standing water.

MIXING;

MONOLEVEL FC should be mechanically mixed using a forced action mixer or in a clean drum using a drill and paddle. A normal concrete mixer is NOT suitable. Use 3-4 litres of clean water per sack which gives a water : powder ratio of 12-16% depending upon the desired consistency for the chosen application technique. For part bags, this equates to approximately 5-6.5 volumes of powder to one volume of water. Normal mixing time depends on the type of mixer used but 2-3 minutes is average. Mix so as to entrain as little air as possible. Use without delay.

PLACING;

MONOLEVEL FC can be applied to localised minor voids and surface defects using a palette knife. For large areas of pore filling, work well into the prepared substrate using a brush, wooden float or “bag rubbing” techniques.
When used as a fair faced finish, Monolevel FC should be applied to the prepared surface using a steel float to provide a smooth, polymer rich surface finish. An initial thin layer should be worked well into the surface, to fill blow holes and minor defects, prior to building up the thickness to a maximum of 6mm. Alternatively spray techniques can be employed.
Once the last layer has stabilised, trowel marks can be removed using a wooden float or damp sponge to produce a surface comparable to emery paper which provides an excellent finish for the subsequent application of a surface coating.

CURING;

Particular attention should be paid to adequate curing with thin screed applications of MONOLEVEL FC. It is important that the surface of the mortar is protected from strong sunlight and drying winds with FLEXCRETE CURING MEMBRANE WB, polythene sheeting, damp hessian or similar.

CLEANING;

All tools should be cleaned with water immediately after use.
