SikaRoof® Adhesive-200

Polyurethane foam

12 months from date of production

The product must be stored in original, unopened and undamaged packaging in an upright position in dry conditions at temperatures between +5°C and +30 °C. Always refer to packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

Beware of condensation. The substrate and uncured applied product must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product. Low temperatures and high humidity conditions increase the probability of blooming.

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

CONSUMPTION ON NEW SUBSTRATES

CONSUMPTION ON EXISTING SUBSTRATES

Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment. It might be necessary to introduce moisture by lightly over-misting the applied adhesive with water.          

• The supporting structure must be of sufficient structural strength to apply all new and existing layers of the roof build-up.

• The complete roof system must be designed and secured against wind uplift loadings.

• The substrate must be clean, and free of all contaminants such as dust, dirt, oil, grease, cement laitance and poorly bonded paint coatings which could reduce the adhesion of the adhesive.

• All dust, loose and friable material must be completely removed from all surfaces before application of adhesive.

• A moist surface is acceptable, however standing water must be avoided and removed before application of adhesive.

• For dry surfaces, typically with less than 35% humidity, moisture will need to introduced to the adhesive after application.

• Primer 610 and Primer 600 can be used to improve the adhesion on certain substrates. Contact Sika Technical Services for more information.

IMPORTANT

Application by trained personnel

The application of this Product must only be carried out by an applicator that is trained or approved by Sika. The applicator must also be experienced in this type of application.

IMPORTANT

Applying sufficient adhesive

Application consumption is based on substrate type and exposure zone. Using insufficient adhesive can have a negative impact on the Product's performance.

1. Refer to the Consumption section to make sure the correct product quantity is applied corresponding to the number of beads per metre and the bead width listed in the Application Instructions.

Colder weather working

Note: At temperatures less than +10 °C the container can be heated in warm water (max. +50 °C) to lower the viscosity and increase fluidity.

Low humidity/dry working

Note: At an atmospheric relative humidity is below 35 % or if the conditions/surfaces are lacking sufficient moisture then spraying a fine mist of water onto the adhesive after application may be required.

BONDING INSULATION BOARDS ON FLAT ROOFS

1. Shake the container vigorously before use.
2. Remove the lid from the container and pull out the pouring spout.
3. IMPORTANT: Only apply the amount of adhesive that can be covered within 5 minutes. Pour out the product onto the substrate in continuous straight-line liquid beads. Apply each line parallel with each other.
4. Central zones: 4 beads per metre. Bead width of 10–20 mm.
5. Perimeter and Corner zones: 6 beads per metre. Bead width of 10–20 mm.
6. Press the insulation panel immediately onto the adhesive with light pressure and adjust into position.
   Note: Do not let the applied adhesive form too much.
7. IMPORTANT: Make sure the adhesive beads have been squeezed flat and have not been absorbed. Lift the insulation board at the leading edge then press board back onto the adhesive. This check is important on very uneven substrates.

BONDING INSULATION BOARDS ON ROOF SLOPES GREATER THAN 10°

Mechanically fix insulation boards or bituminous vapour control layers to prevent slipping until the adhesive has cured.
