EQUIPMENT

Mixing

  • Electric drill paddle mixer (> 700 W, 300 to 500 rpm)

  
Application

  • Hard bristled brush
  • Squeegee
  • Flat trowel

MIXING

IMPORTANT

Do not add water in any circumstances.

  

Waterproofing coating

  1. Pour full quantity of SikaTop®-107 Seal IN Part A into a clean mixing container.
  2. While stirring slowly, add SikaTop®-107 Seal IN Part B.
  3. Mix thoroughly for 3 minutes, until free from lumps and smooth consistency is achieved.

  

Waterproofing mortar

  1. Pour 90 % of SikaTop®-107 Seal IN Part A into a clean mixing container.
  2. While stirring slowly, add SikaTop®-107 Seal IN Part B.
  3. Mix thoroughly for 3 minutes, until free from lumps and smooth consistency is achieved.

APPLICATION

IMPORTANT

SikaTop®-107 Seal IN may display signs of “blooming” after rain or in damp weather. This does not affect the performance of the coating in any way.

IMPORTANT

Do not apply in direct sun and/or strong wind.

IMPORTANT

In areas of severe water penetration, three coats might be required.

IMPORTANT

Protect freshly applied material from freezing conditions, rains etc.

  

Detailing

  1. Seal all penetrations with a suitable Sika sealant like SikaSwell® S-2 or Sikagard® 694 F(I) epoxy putty to prevent any leakage from the periphery of the down take pipes.
  2. Additionally, if so desired cut Sika® Fabric-50 to desired dimensions for detailing on intersections and also around pipe penetration by embedding it with the SikaTop®-107 Seal IN. 
  3. Sika® SealTape F is recommended to be used as a component of a composite sealing system in conjunction with SikaCeram® tile adhesive and ceramic tiles to achieve water tightness in wet rooms and around wet areas.

  

Waterproofing coating 

  1. Thoroughly pre-wet the prepared substrate (2 hours recommended) before application. Keep the surface wet and do not allow to dry. Before application remove excess water, e.g. with a clean sponge. The surface must appear a dark matt appearance without shining and surface pores and cavities must not contain water.
  2. Apply the first coat of SikaTop®-107 Seal IN with a hard bristled brush or broom applied in the same direction and leave to harden for 2 to 6 hours.
  3. (Optional) Wherever coating is to be reinforced with glass fabric, lay Sika® Fabric-50 into the freshly applied base coat and embed firmly into the wet coat with brush. 
  4. Apply the second coat of SikaTop®-107 Seal IN in crosswise direction to the first application as soon as first coat has hardened.

  

Waterproofing mortar

  1. Thoroughly pre-wet the prepared substrate (2 hours recommended) before application. Keep the surface wet and do not allow to dry. Before application remove excess water, e.g. with a clean sponge. The surface must appear a dark matt appearance without shining and surface pores and cavities must not contain water.
  2. Apply the first coat of SikaTop®-107 Seal IN by a flat trowel applied in the same direction and leave to harden for 2 to 6 hours. For pore / blowhole filling, tightly trowel into the pores / blowholes of the surface.
  3. (Optional) Wherever coating is to be reinforced with glass fabric, lay Sika® Fabric-50 into the freshly applied base coat and embed firmly into the wet coat with trowel.
  4. Apply the second coat of SikaTop®-107 Seal IN in crosswise direction to the first application as soon as first coat has hardened.

Note:

If the second coat is applied 12 hours or later to first coat, the first coat shall be slightly pre-wetted by using a fine spray.

  

IMPORTANT

Slight fabric marks may be visible after application of the second coat, but it will have no adverse bearing on the performance of the waterproofing system.

  

Protection

  1. The top coat while wet, sprinkle clean quartz sand. 
  2. Once top coat has sufficiently cured, apply protection plaster, mortar, screed or any other adhesive layer. A bonding agent may be necessary.
  3. Alternatively, a separation layer like PE sheet or geotextile can be used before any plaster / screed / interlocking paver blocks.
 

CURING TREATMENT

Cure SikaTop®-107 Seal IN for minimum 7 days to ensure full cement hydration and minimise cracks. Use wet hessian cloth, spray curing or similar approved methods during the recommended period of curing.

CLEANING OF TOOLS

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