SELF LEVELING COMPOUNDS

R - 17F

RAPID SETTING AND HARDENING EXTERNAL REPAIR MORTAR

DESCRIPTION

R - 17F is a rapid setting and hardening, slump free mortar which is ideal for external or internal repairs. The mortar sets and hardens rapidly to give a repair of exceptional strength and hardness. The mixed mortar sets after 20 minutes and can be trafficked after only 2 - 3 hours at 27± 1ºC. A 46 is ready to receive floor coverings that are not sensitive to moisture, such as ceramic tiles after 24 hours at 27± 1ºC.

FEATURES

• For infilling holes around fittings and for patch work on wall and floor areas
• For internal and external use
• Rapid hardening - walkable in 2 - 3 hours
• For repairing stair treads and risers
• To produce gradients for ramps
• To smooth wall and floor areas from 2 to 30 mm thick
• Easy to smooth and float
• Stress and crack free
• Wearing surface in lightly trafficked areas
• Ideal for patch repairs prior to the application of suitable damp proof membranes

USE

R - 17F is ideal for : - Repairing and refacing external concrete stairtreads and risers, brickwork (not lightweight concrete), renders and concrete floors.
- Filling and patching cracks in walls and floors.
- Making good around pipework, door and window frames.
- Forming ramps from 2 mm to 30 mm in thickness.
- Making patch repairs prior to the application of a damp proof membrane.
- Forming coves.
- R - 17F may be used as a wearing surface in lightly trafficked areas. For heavy duty areas, consult CLI for guidance.

SURFACE PREPARATION

R - 17F can be applied to dry or moist substrates providing they are hard and the surface is sound and free of dust, grease, oil and other barriers to adhesion. Worn or trafficked surfaces should be mechanically prepared to remove contamination and expose a clean surface to ensure good adhesion. Very dense, smooth, impervious surfaces should be primed with sand blinded CLI IF - 3 E Solvent Free Epoxy Primer. Priming is not usually necessary on concrete, cement/sand, brickwork etc., unless the surface is extremely porous. On absorbent substrates, the mortar must be initially applied firmly in a thin layer, after that, apply the mortar to the required thickness.

MIXING

The R - 17F powder is added to the required amount of clean water in a clean mixing container and mixed thoroughly to obtain a lump free and slump resistant mortar.

The mix proportions are:-
25kg R - 17F powder to 6 - 7 litres of water,
11kg R - 17F powder to 2.7 - 3 litres of water.

Avoid using too much water. The mixed mortar has a working time of 15 to 20 minutes at 27 ± 1ºC, this time being extended at lower, and reduced at higher temperatures.
A 46 can be applied from 2 mm to a maximum of 30 mm in thickness.
R - 17F can be applied from 2 mm to a maximum of 30 mm in thickness.

APPLICATION

Repairs

Apply the mortar with a trowel to holes, cracks and damaged areas, ensuring that the mortar "wets" the surface by trowelling in firmly, leaving the repair proud. After about 10 minutes trim off excess and finish off with a wet trowel, sponge or sponge float to obtain a smooth surface. This smoothing operation needs to be completed within 15 minutes of application. As soon as the R - 17F repair has hardened, the surface of the floor, stairtread etc., can be levelled, if necessary, with the appropriate CLI sub-floor smoothing compound.

Smoothing and Refacing

Apply the mixed mortar with a trowel to the required thickness taking into account the short working time. The material may be finished with a wet trowel after 10 to 15 minutes to provide a finish suitable for direct application of tiles or stone.

Apply at temperatures above 5°C. The finished surface has to be protected against direct sunlight and draughts which could lead to rapid drying of the surface.

CLEANING

R - 17F can be removed from tools and equipment by washing in clean water immediately after use. Any hardened material will need to be removed mechanically.

STORAGE AND SHELF LIFE

R - 17F must be stored in unopened packaging, clear of the ground in cool dry conditions and be protected from excessive draught. If stored correctly, as detailed above, the shelf life of this product is 12 months from the date shown on the packaging. The activity of the reducing agent (added to control the level of soluble Chromium VI) will be maintained and this product will contain, when mixed with water, no more than 0.0002% (2ppm) soluble Chromium VI of the total dry weight of the cement content of this product. R - 17F must not be used after the end of the declared storage period.

PRECAUTIONS

R - 17F is considered non-hazardous in normal usage. The presence of cement in the product gives an alkaline mortar which may cause some local irritation if prolonged contact with the skin takes place. Care should be taken to avoid inhalation or ingestion of dust and prevent contact with the eyes. may cause some local irritation if prolonged contact with the skin takes place. Care should be taken to avoid inhalation or ingestion of dust and prevent contact with the eyes.

DISPOSAL / SPILLAGE

Spillage of any of the component products should be absorbed onto sand or other inert materials and transferred to a suitable disposable vessel. Disposal of such spillage or empty packaging should be in accordance with local waste disposal authority regulations.
