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  and side laps of metal and 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.
