Product Specification

Surface Preparation

Substrate Quality

• The surface must be sound, of sufficient strength, clean, dry and free of dirt, oil, grease and other contamination. Depending on the material the substrate must be primed or mechanically cleaned.
• Grinding may be necessary to level the surface.
• Suitable substrates are such as: concrete, bituminous felts and coatings, metal, brickwork, asbestos cement, ceramic tiles, wooden substrates.

Application

• Prior the application of the liquid membrane the priming coat if used must have cured tack-free.
• Damageable areas (handrails etc.) have to be protected with tape or plastic wrapping.

Application Over Bolt Heads

• Pre-cut 50 mm × 50 mm squares of Sikalastic® Flexistrip, remove the backing and fix Sikalastic® Flexistrip by light pressure onto the bold heads.
• Do not exert hard pressure.
• Apply a first layer of the coating on an area of approx. 100 mm x 100 mm over Sikalastic® Flexistrip
• Embed Sika® Reemat Premium approx. 1 cm beyond / away from the edge of the liquid applied membrane and roll it into the fresh membrane.

Application Over End & Side Laps Of Metal & Fibre Cement Sheets

• Remove the backing and fix Sikalastic® Flexistrip by light pressure centralised over the side or end laps.
• Apply a full coat of the coating as required, approximately 33% wider than the tape and whilst wet, insert Sika® Flexitape Heavy into the wet membrane by gentle pressure from a loaded brush, thus applying further material until the tape is obliterated. Embed Sika® Flexitape Heavy into the wet membrane without tension or stretching of the tape.
• Lay the tape as naturally as possible, direct from the roll, inner face upwards in order to avoid edge curl.

Limitations:

• Limitations will be dictated by the individual liquid being used.
