Montage Instruction

2. Measurements

Measure the dimensions of the window sill:

1. Length in the light of the window (photo 2.)
2. The depth of the window's light (together with the part of the window sill that will be enter under the window frame) (photo 3.)
3. part of the window sill that will protrude from the window (from rule 3 - 16 cm depending on the stucco installed). (photo 4.)

3. Window Sill Cutting

Conduct cutting using a wood saw (photo 5.), a saw blade or an angle grinder (photo 6.).

4. Gluing

Before gluing, make sure that the cut sill fits the window (photo 8.). For gluing, use Ceresit CT84 polystyrene adhesive. Apply glue around the perimeter of the window sill (~ 2cm from the edge), in strips on the window sill (photo 9.) and on the wall (photo 10) (maximum spacing between glue bands ~ 5 cm). After 2-4 minutes after applying the adhesive, the sill should be applied to the wall and pressed with a small force using a long lath. The window sill should be mounted so that the drop is not less than 7 ° (photo 11.). In order to ensure a proper drop, you can use spacers (photo 10.).

5. Finishing Window Sill Ends

The window sill ends (areas without a coating) should be covered with the WMB repair compound (photo 12) so as to cover the entire exposed surface of the expanded polystyrene (photo 13.).

6. Seam Grouting with Wall and Window

Connection of the window sill with wall should be protected with Ceresit CS29 polyurethane sealer. To do this, you need to secure with window (wall) masking tape window (wall) and window sill (photo 14). The joints must be filled continuously (without technological breaks), leaving no empty spaces in them (photo 15). Within 5 minutes, the filling surface should be sprayed with an aqueous soap solution and smoothed with a similarly wetted tool, while removing the excess material (photo 16, 17).

7. Painting

After drying of the repair mass and sealer (about 24 hours depending on the conditions), start painting. Recommend application of Tikkurila Finngard Elastomeric façade paint (photo 18). The surface must be load-bearing, dry and clean. Humidity of the painted substrate should not exceed 4%. Mix the paint. Do not dilute. Apply the product once with a brush (photo 19.) or with a roller (photo 20.), with a thick layer of approx. 300-400 g / m2. With a two-layer system (ensuring consumption 3.3-4.5 m2 / l for 1 layer) keep min. 16-hour time interval between applying subsequent layers. Work with the "wet on wet" method, painting the surface continuously to avoid traces of the used painting tool, streaks and discoloration. Provide enough paint from one production batch.
