BAL Level Out External Levelling Compound 25kg

Description

BAL Level Out External Levelling Compound is a fast-setting external levelling compound for concrete bases, part of the BAL Eternal Range of tiling products for outdoor patios. It is designed to be used in conjunction with the other BAL External Products – BAL External Terrace Grout, BAL External Priming Slurry Bond and BAL External Bedding Mortar.

BAL Level Out is designed for creating a suitable substrate for laying tiles on externally, by levelling and smoothing rough, uneven or impact damaged concrete substrates. BAL Level Out External Levelling Compound is suitable for use in dry/wet environments, including totally immersed areas such as in swimming pools. It can be used in both domestic and commercial areas.

BAL Level Out can be used at a bed depth from 2mm up to 20mm in thickness and can receive ceramic or natural stone tiles after 3 hours at 20°C. A longer drying period will be required at thicker depths and/or lower site temperatures.

However, BAL Level Out is NOT suitable for:

• Use as a wearing screed.
• For levelling sloped backgrounds where falls have been intentionally designed to divert water to a primary drainage point. Any substrate that has been laid to falls should always maintain a safe slope for maximum effective drainage.

BAL Level Out External Levelling Compound Usage Instructions:

• Surface Preparation: Ensure concrete surfaces are dry, sound, and free from grease, dust and any other contamination/barriers to adhesion. Ensure direct-to-earth sub-floors incorporate an effective damp proof membrane. Concrete must be fully cured and free from efflorescence, laitance, dirt, polished concrete, and other loose materials. Remove using suitable mechanical methods. Some exposed aggregate should be visible in the surface but not loose.
  Allow the following minimum drying times:
  – Concrete: 6 weeks
  Thoroughly dampen the substrate with water, taking care not to leave any pools of water, before applying the product to the dampened substrate.
  Note: Any structural movement or live joints in the substrate must be carried through the BAL Level Out to the surface.
• Mixing: One 25kg bag of BAL Level Out External Levelling Compound requires approx. 5.25 litres of water. Mix thoroughly until a lump-free mortar is obtained.
  If gradient levelling had to be carried out, the water content must be reduced. To pump the mortar, use continuous pumps with a capacity of 20-40 litres of mortar per minute.
  Do not use excess water as this will reduce the strength of the set and hardened mortar.
  The use of a mixing paddle with a 10m chuck slow speed (600-1000 rpm) electric drill makes light work of mixing.
  BAL Level Out should be applied within 30 minutes at 20°C. This time is extended at lower and reduced at higher temperatures.
  NOTE: Working time/setting time will vary slightly with temperature: higher temperatures = shorter; lower temperatures = longer
• Application: Pour the mixed BAL Level Out onto the prepared substrate. The mixed mortar will flow out and self-smooth during the first 10 minutes of its 30-minute working time. Spread the mortar using a steel trowel or float.
  For large areas, it’s recommended to use a gauging tool with thickness height adjustment to spread the mortar. A long handled smoothing trowel can be used to simplify the finishing operation.
  The applied BAL Level Out surface can be left with a trowelled finish. Once set, the freshly applied BAL Level Out External Levelling Compound should be protected from adverse climatic conditions, e.g. rapid drying air flow, direct strong sunlight, rain, frost etc., until hardened.
  Apply BAL Level Out External Levelling Compound at temperatures above 5°C.
  If a second layer of BAL Level Out is required, this should be applied after the first layer has fully hardened. The first layer should be machine sanded (paper 16 to 36), cleaned and dampened down.
