ARENA RepairMaster R500 REPAIR COMPOSITION FOR CONCRETE HIGH-MARK

The dry construction mix ARENA RepairMaster R500 is the effective repair structure of superficial action recommended for production of responsible construction and recovery work. The most important components of repair structure for ARENA RepairMaster R500 concrete are the quick-hardening portlandtsement, a complex of the special modifying additives and the polymeric reinforcing fibers intended for giving to the grabbed solution of special durability. As filler – a basic basis of the mix ARENA RepairMaster R500, clean quartz sand of different fractions is applied.

Purpose:

The dry mix is intended for restoration of geometrical and operational parameters of a structure by their surface restoration. Can be applied by dry or wet tampering. DESCRIPTION: Dry construction mixture waterproof surface to stop active leaks mixture, consists of a mixture of alumina and Portland cement, quartz sand and a complex of additives accelerators for setting and hardening, as well as additives that prevent the mixture from blurring.

Benefits:

  • High strength (especially in early hardening).
  • No shrinkage.
  • High adhesion to the substrate and water resistance.
  • The possibility of applying up to -10°С (ARENA Repair Master R500 Winter).

Material application technology

WORKING  PROCESS:

Conduct a visual and instructional assessment of defective areas of concrete to calculate the required amount of materials. Clean the damaged areas from structurally weak concrete of other contaminants, preventing adhesion of the mortar to the surface of the repaired concrete. When bare reinforcing bars, remove the concrete around them no less than 15mm. If there are active leaks, remove them with a dry ARENA PlugMix PW "Hydraulic plug" mixture. Attention! Before applying ARENA RepairMaster R500, it is necessary to moisten the substrate with water to the maximum possible saturation.

PREPARATION OF SOLVENT MIXTURE:

Attention! For preparation of solution mix to use only clear water and a container. To prepare such volume of solution mix which can be developed within 60 minutes from the moment of mixing with water. The optimum temperature of the mixing water of 20°C per 1 kg of dry mixture requires 0,15-0,16 liters of water. It is best to mix with a low-speed drill. Mix for 3 minutes before forming a homogeneous plastic mass without lumps. Dissolve the mortar during use to maintain its original consistency. Re-adding water to the solution is not allowed. At temperatures close to 0°C, use a dry mixture of ARENA Repair Master R500 Winter.

APPLICATION:

Work should be done at a temperature of at least 5°C. Before applying the mortar mixture on the concrete surface of the repaired area should be abundantly moistened. Depending on the amount of work, the mortar can be applied with a trowel, a spatula manually or by wet-rolling. The optimum layer thickness of the applied material is 10 mm. When using a construction mixture ARENA Repair Master R500+ the maximum layer thickness of the applied material is 40 mm. The subsequent layers can be applied after 60-120 minutes, pre-moisturizing. The application of the repair mixture on large areas must be done on a masonry net. CARE OF PROCESSED SURFACE: It is necessary to ensure that the treated surfaces remain  moist  for  3  days.  For  what  you  need  to moisturize the surface 2-3 times a day.

Manufacturer`s warranty

The manufacturer guarantees compliance of mix to requirements of specifications at observance by the consumer of storage precautions and indications of this instruction. A warranty period of container storage of the manufacturer – 18 months from the date of production on condition of undisturbed tightness of an original packing.

Safety:

It is necessary to avoid hit of mix in eyes and on skin. Mix contains cement and in interaction with water gives alkaline reaction therefore during the work it is necessary to use rubber gloves and goggles. At hit of mix in eyes it is necessary to wash them with water and to ask for the help the doctor. Storage conditions: Storage is allowed at any humidity and temperature from - 60oC to 50oC.
