ESTERDAN 25 P ELAST AUTOADHESIVE
Waterproofing sheet of SBS modified bitumen with non-protected surface finished with polyethylene film.
Product variations:
ESTERDAN 25 P ELAST. AUTOADHESIVE is a waterproofing bituminous self-adhesive membrane.
Composed of a non-woven polyester felt reinforcement, covered with SBS modified bitumen mastic, self-adhesive on the lower side. A polyethylene film is used as anti-adherent material on the top side and a siliconized releasable polypropylene film is used on the bottom side.
Instruction for Use
- Surface preparation:
- Concrete must be dry, clean and free from sharp projections such as nail heads and concrete nibs.
- Remove all surface imperfections, protrusions, cavities, structurally unsound and friable concrete and repair with a suitable repair mortar.
- Remove contaminants such as grease, oil, dust, dirt, loose stones, debris and wax from exposed concrete.
- Concrete must be properly dried.
- Substrate should be prepared using a primer either IMPRIDAN 100, CURIDAN, MAXDAN or MAXDAN CAUCHO, at the recommended rate (approximately 0,200-0,300 kg/m2) prior to installation of ESTERDAN 25 P ELAST. AUTOADHESIVO.
- Primer should be dry before the application of the membrane. Drying time depends of the temperature and humidity.
- In case that the support is a thermal insulation board, the suitability of the thermal insulation board with ESTERDAN 25 P ELAST.
AUTOADHESIVO must be checked. Alignment: - Start the installation of all membrane plies from the low point or drains, so the flow of water is over or parallel to the plies, but never against the laps. All overlaps at the membrane seams shall be installed so as to have “up” slope laps over “down” slope laps. Membrane installation:
- Roll the bitumen membrane into position and cut to length.
- Roll back the membrane for a portion of its length (approximately 50%).
- Carefully cut across the backing release film and peel the film off the roll.
- Peel the leading edge of the backing film up and tuck it under the roll to enable release of the remainder when unreeling.
- Roll the membrane forward, pressing downward and outward, ensuring that no air pockets are trapped.
- Roll back the other portion of the membrane to the leading edge of release film.
- Peel the remainder of the film away while pushing the roll forward, pressing downward and outward, ensuring that no air pockets are trapped.
- On completion, use a soft broom or roller to apply pressure over the total area.
- The second layer or the top layer/cap sheet is laid over ESTERDAN 25 P ELAST. AUTOADHESIVO in the same direction, and fully bonded. Laps between top layer/cap sheet and ESTERDAN 25 P ELAST. AUTOADHESIVO should be offset by a minimum of 300 mm.
ESTERDAN 25 P ELAST. AUTOADHESIVO is achieved by removal of the backing release film while unrolling the membrane onto the substrate with side laps of 80 mm and end laps of 10 mm. The full work sequence should be as follows.
Indications and Important Recommendations
- Exposure to the sun can make it difficult to remove the release film. The temperature of the membraneduring installation must not exceed 45°C.
- It must not be installed when the ambient, product or substrate temperature is below +10°C.
- Not suitable as cap sheet on green roofs; use GARDEN variant.
Maintenance Recommendations
- Please refer to DANOSA UK Technical Statement ‘Flat Roof Waterproofing – Cleaning and Maintenance Recommendations’.
