VBCS008 - Winkler BC Seal Band 0.8m x 10m roll Butyl Self-Adhesive Band used for reinforcing corners, part of the Winkler One waterproofing system.

Self adhesive band based on butylic mastic covered with non-woven which allows the deformation of the product. The adhesive side is protected by peel off support.

Winkler ONE - BC Seal Band

  • Sealing wall-to-floor joints on cementitious substrates, bricks, asbestos cement, metal or tiled flooring before applying liquid or cement waterproofing products from WINKLER range. The non-woven fabric covering adapts to the shape of the support, can be easily shaped to fit corners, drains, pipes etc. where can be used in combination with BC SEAL PAD.

  • Remove the protection, put the band on the support avoiding the formation of air bubbles between the butyl and the support. For joints superimpose the products of at least 5 cm.
  • For sealing substrates subject to significant expansion, it is recommended to provide a method of application of BC SEAL BAND, suitable to withstand such tensions. For example, in the case of overlapping between corrugated sheets, apply the two edges of the strip on the portions of the sheet to be connected, leaving the central part free, thus creating an "omega". Apply at temperatures between +5°C and +40°C.
Surface Preparation
  • Application surfaces must be clean, dry and free from dust, oils, foreign or non-stick substances. On powdery substrates it is advisable to favour the adhesion, a prior application of WINFIX CONCRETE.
Useful Advice
  • Prior the application it is advisable to restore any irregularities on the surface, glue any detached tiles and check for hidden humidity to avoid the formation of vapour tensions. Avoid use when rainy weather is imminent and on wet surfaces. Cover the product within 24 hours, after its application.

Fast Curing at 0°C

It is a fast curing product that resist at high and low temperature remaining stable at thermal shocks. It tolerates precipitations in a short period of time after its application. Although not fully cured, the product is rain-proofed after just a few hours from its application.

The need of new products and solutions is detected and studied by the Winkler R&D personal since 1987, both in the laboratory and directly with coating applicators onsite.

The average roofer loses approx. 30% of his potential yearly income because he cannot easily waterproof during wintertime

Clean all substrate surfaces thoroughly to eliminate dirt, dust, and loose materials, any form of oil or grease and foreign or bonding-proof matters. There is no need for the substrate surface to be dry, but ponding water shall be removed prior to the application of ONE.

After thoroughly cleaning the surface to be treated, apply ONE (with a consumption of 0.70 gallons/sq.ft. - 400 g / m²) evenly. Immediately lay ONE MAT (90g/m² non-woven reinforcement), by using a spiked roller, and drown it with other 1.23-1.58 gallons/sq.ft.(700-900 g/m²) of ONE.

The use of the bubble-breaker roller after the application of the second coat is always recommended. Wait for the time required for the application of the 2nd coat (see temperature table) and complete the application with the remaining 1.05-1.23 gallons/sq.ft.(600-700 g/m²) provided.

Useful Tips

Do NOT dilute
Apply BC SEAL BAND (Self-Adhesive Butyl Tape) at wall to floor type corners, balcony terminations, around skylights or other alike penetrations.

Use BC SEAL PAD (Self-Adhesive Butyl Square Pad) around tubes, vent pipes, drains, etc. In case the substrate is damp, first apply a skim coat of ONE, prior to the application of any butyl accessory.

After the product dries, resume the normal application of the butyl accessories. Control cuts, contraction and/or most structural joints will be sealed, using the waterproofing elastic band WINJOINT BAND as follow:
Ensure the surface to be treated is clean.

Over the clean substrate apply ONE in two stripes 5 cm wide along each side of the joint, without covering the joint line.

Immediately place WINJOINT BAND over the wet stripes of ONE (the central part of the band will cover the joint line and the lateral wings of the band will be embedded onto the wet stripes of ONE.

After the product dries, cover the lateral wings of the WINJOINT BAND with a skim film of ONE.
