Morcemrest® RF 35 R3
R3 mono-component medium resistant repair mortar.
Additional information
Composition
Product based on special cements, selected aggregates and additives, reinforced with fibres.
Features and applications
- Class R3 repair mortar in compliance with EN-1504-3
- High strength adhesion for bonding to concrete and average module.
- Thixotropic, no sagging on roof applications.
- Water vapour permeable.
- Retraction compensated to minimise risk of cracking.
- Good resistance to chlorides.
- Resistant to freeze-thawing cycles.
- Good workability
- High resistance to carbonation.
- Suitable for indoor and outdoor applications.
- Weather resistant.
- Repairs to structural elements such as: balcony overhangs, roofs, car parks, beams / pillars on commercial and residential buildings, prefabricated panels, building façades.
- Regularisation of concrete surfaces.
- Lining of canals, tunnels, bridge and balcony overhangs.
- Rendering of elevator pits, chambers, etc.
- Foundations and repairs to paving.
Substrates
- Substrate must be in good condition, clean, free of grease, oil and badly bonded parts (minimum traction resistance of 1.5 MPa).
- If necessary, make a preparation preferably by using mechanical means and leave to cover the healthy concrete.
- Absorbent substrates must be dampened prior to saturating them, avoiding water logging, apply the product once the surface has acquired a matt appearance.
- If there are any reinforcements, these must first be cleaned of rust, grease and other badly bonded parts. If they are rusted, clean them with sand jets or with a grooved metal brush. Protect the rust with IMPLAREST C.
- On joints of vertical and horizontal supporting walls widen the joint by cutting it to a width of 10 mm with a radial arm saw, and removing the cut material.
Instructions for use
Mixing the mortar:
- Add 2/3 parts of water and progressively mix the total amount of powder while stirring. Next add the remaining water and mix for 2 more minutes. Do not prepare more product than is going to be used for 30 minutes (at + 20ºC).
Application:
- Apply MORCEMREST RF 35 with a trowel or spray gun, apply pressure to ensure adhesion and compact the material firmly.
- MORCEMREST RF 35 can be applied in several layers, with a minimum thickness of 5 mm per layer. On vertical surfaces thicknesses of up to 35 mm can be applied without the aid of molds. The maximum thickness per layer on horizontal surfaces is 75 mm.
- On vertical and horizontal interior wall joints, completely fill the width of the joint.
Curing:
- Protect from wind, ice and sun while product is hardening. To avoid excessive drying it is necessary to cover the surface with moist sackcloth or plastic while curing.
- The curing operation is necessary in all cases.
Cautions and recommendations
- Do not extra water to the mortar other than the recommended amount nor remix.
- Do not apply under 5ºC nor above 30ºC.
- Do not add cement, sand or other substances that could affect the material's properties.
- On surfaces exposed to exceptional circumstances, it is advisable to use the epoxy bonding bridge IMPLAREST EPW.
- Tools and instruments should be washed with water immediately after use, to avoid hardening of the material which would need to be removed mechanically.
- Consult the Technical Department for any application not specified in this Technical Datasheet.
- For all information regarding safety during handling, transport, storage and use of product please consult the current version of the Product's Safety Sheet.
