SikaTop®-599 Seal

(former MSeal 599)

High range elastomeric, cement-based waterproof coating for concrete and masonry

SikaTop®-599 Seal is a blend of Portland cements, selected silica, micro-fibres and modifying agents. When mixed to a slurry consistency with the acrylic polymer emulsion, it can be easily applied by brush or spray equipment. It cures to give an elastomeric flexible membrane.
The 2mm thick SikaTop®-599 Seal membrane will accommodate movement up to 0.5 mm, or 1.2 mm when reinforced with FIBER mesh.

  • Remains flexible when submerged.
  • Good chemical resistance against soft water, domestic waste water, manure or other liquids moderately aggressive to mineral substrates.
  • Freeze-thaw resistant.
  • Water vapour permeable.
  • CO² barrier.
  • Crack bridging.
  • UV stable.
  • Simple and fast method of treating cracks and joints.
  • Quick and easy brush or spray application.
  • Can be applied to damp substrates.
  • Thin layer application.
  • Equipment to be cleaned simply with water.

Usage

  • For waterproofing water-retaining structures which may be subject to movement like water tanks, pools, reservoirs, etc.
  • As part of the MasterSeal basementwaterproofing system, in areas sensitive to movement, vibrations and slight settlement.
  • To protect concrete from water, carbonation and de-icing salts.
  • Suitable for internal and external use, against positive and negative water pressure.
  • Fiber mesh can be used in strip form over joints and cracks or as reinforcement for the whole application.

Application steps

SUBSTRATE PREPARATION

The surface to be coated must be clean and sound. Remove all traces of formwork, release agents, previous coatings, laitance, organic growth and any other contaminant that may affect the bond adversely. Suitable cleaning methods include high-pressure water treatment and grit blasting. NOT recommended are aggressive percussive methods such as scabbling. After the above treatment, surfaces must be thoroughly rinsed with clean potable water to remove all dust and loose particles.
For Cracks and bolt holes please consulted Sika Solutions technical team for repair advise.

MIXING

Important: Do not add any additional water or other constituents.

  1. Shake carefully Part. A before mixing.
  2. Pour ~½ of Part. A into a suitable mixing container.
  3. Add Part. B slowly while mixing with a low speed (~500 rpm) electric single paddle mixer or other suitableequipment until a consistent mix has been achieved.
  4. Add the remaining amount of Part. A.
  5. Mix thoroughly for at least 3 minutes to achieve a smooth consistent mix.

CURING TREATMENT

Under hot or excessive drying conditions adequate protective shielding should be foreseen. In cold and humid areas it may be necessary to leave the application for a longer curing period. SikaTop®-599 Seal needs to dry under air dry circumstances.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
