EXTOSEAL ENCORS
Retrofitting a sub-sill
1. Apply tape at the window frame
Measure out the required length of tape (width of opening + 2 x additional allowance) and cut to size. Gradually remove the narrow release film and stick the tape onto the window frame in the window sill recess.

2. Fold up onto the reveals
Seal the transition between the areas of responsibility of different trades using a suitable sealant. Fold the tape up onto the reveals in the corners and stick it to the window frame. The additional allowance (excess length) for the tape depends on the subsequent procedure: approx. 10-15 cm (4” to 6”) in the case of covering with a reveal plate or for a back-ventilated structure; or approx. 6 cm (2 3/8”) (from upper edge of window sill profile) for a directly plastered window reveal.

3. Apply tape to the sill surface
Gradually remove the main strip of release film and stick the tape onto the sill surface. Ensure that the tape is guided right into the corners. Rub using the PRESSFIX application tool to secure the adhesive bond.

4. Cut off excess tape at window reveals
Cut off any excess tape on the vertical window reveals so that it is flush with the front edge of the wood-fibre insulating panels.

5. Cut off horizontal excess tape
Cut off any protruding excess tape using a spacer, allowing approx. 15 mm (5/8”) so that the tape can subsequently be applied to the plaster or directly stuck onto a suitable drip profile.

6. Install the window sill
You now have a finished lower sub-sill using EXTOSEAL ENCORS! In a subsequent step, the plasterer will stick the plaster-sealing strip to the protruding tape. The fitting of a window sill provides long-term protection for the reveal.
