EXTOSEAL ENCORS

1. Preparation

Select the width of the tape so that the entire side of the window frame can be covered and that a minimum width of 5 cm (2") of the concrete is covered.

2. Check the initial situation

The windows and all fasteners must be correctly installed.

3. Clean the subsurface

Remove loose material using a brush or vacuum cleaner.
Strengthen unstable (e.g. crumbling) subsurfaces with TESCON PRIMER, if necessary.

4. Cover brackets

Select the width of EXTOSEAL ENCORS so that brackets are covered by at least 3 cm (1 1/4").
The minimum coverage width on the wall is 5 cm (2").

Alternatively, large side lengths can be covered with suitably cut sections of EXTOSEAL ENCORS.

Practical tip

Create a marking in order to achieve a uniform lateral protrusion distance for EXTOSEAL ENCORS at the centre of the window.

Practical tip

To ensure a straight adhesive joint on the front of the window frame, apply markings 1 cm (3/8") from the outer side of the frame.
This is necessary for the joint at the top.
This is recommended particularly for the side / bottom joints for plastic windows.

5. Cut the tape to size

When cutting tape for the bottom and side adhesive tape sections, add 2 x 5 cm (2") to the relevant frame dimension, and add 2 x 10 cm (4") for the top tape piece so that water resistant adhesive bonds can subsequently be created at the corners.
If joints are created in a number of parts for a particular side, the tape overlap must be at least 3 cm (1 1/4").

6. Stick to the window

Create adhesive bonds in a waterproof manner starting at the bottom of the window and working up.

Fold the tape to half of its total length and remove the narrow release film strip on one side.
Position the tape at the centre of the window and stick in place.
Completely remove the narrow release film strip, unfold the adhesive tape and stick it to the window frame.

7. Stick to the wall

To create an adhesive bond with the wall, remove the remaining release film strips and stick the tape to the frame and/or the masonry subsurface.
Avoid hollows between the window frame and the masonry/concrete subsurface so that the thermal insulation material can be pushed right up to the window frame.
Rub the adhesive tape using the PRESSFIX application tool to secure it.

8. Create adhesive joints at the corners

Pre-stretch EXTOSEAL ENCORS uniformly so that the adhesive tape can be stuck around the corners of the window frame both to the frame and to the masonry/concrete without any tension.
After sticking, rub the tape firmly into place using PRESSFIX.

9. Top connection

Guide 1 cm (3/8") of the upper adhesive joint onto the front of the window frame so that water can run off in waterproof manner.
If the distance between the window frame and the wall is greater than 50 mm (2"), it is recommended to use a slope wedge.
