SikaTop®-300 Seal

Polymer-Modified Highly Elastic Cementitious Waterproofing Coating

SikaTop®-300 Seal is a 2-component, polymer-modified elastic cementitious waterproofing coating. It is applied to concrete and mortar as an elastic waterproofing coating to prevent water infiltration.

  • Highly elastic with good crack bridging capability
  • Pre-batched components with consistance quality
  • Easily applied by roller or brush
  • Good adhesion to sound substrates
  • Cementitous with low VOC
  • Impermeable
  • Increased frost and salt resistance
  • Decreases carbon dioxide penetration
  • Non-toxic, same as cement
  • Resistant to freezing & thawing (-10 °C)

Consumption

Consumption

Approx. 1 kg/m²/coat

(Overall coating thickness depend on the application area, substrate roughness and surface profile)

  

  • SikaTop®-300 Seal must be applied in a minimum of 2 coats.
  • For high risk areas, apply an addition third coat.
Application steps

EQUIPMENT

  • Slow Speed Mixer (maximum 500 rpm)
  • Mixing Paddle with uplifted notched disk.

MIXING

Shake component A before using it. Pour the whole component A (liquid) into a clean mixing container. While mixing at low speed, add slowly

component B (powder) to the liquid component. Continue mixing for approx. 3 minutes until a creamy, lump free consistency is achieved.

APPLICATION

Whilst the substrate is still damp but free of standing water, apply the first coat by brush, roller or squeegee, working the material well into the surface to achieve full bond. Allow 2-4 hours (at 25 oC) for the first coat to cure before applying following coats.

  

An additional stripe coat is recommended over cracks, wall/floor intersections, etc. as these locations are where movement is most likely to be expected in service.

   

Sika® SealTape F is a recommended product to be used in conjunction with SikaTop®-300 Seal in order to achieve advanced water tightness in wet rooms and around wet area.

CURING TREATMENT

For cement based products, proper curing is important. Protect newly applied SikaTop®-300 Seal against direct sunlight, wind, rain and frost to ensure full cement hydration to minimize cracking.

CLEANING OF EQUIPMENT

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