APPLICATION INSTRUCTIONSSUBSTRATE QUALITY

Substrate must be homogeneous and offer sufficientstructural properties to resist the forces generated bywind suction.

SUBSTRATE PREPARATION

The substrate must be clean, and free of all contamin-ants such as dust, dirt, oil, grease, cement laitance andpoorly bonded paint coatings which could affect adhe-sion of the adhesive.All dust, loose and friable materi-al must be completely removed from all surfaces be-foreapplication of adhesive.Damp surface is acceptablehowever wet, saturated substrate or standing watershould be avoided.Sika® RoofBond adheres withoutprimers or activators.

MIXING

Ready to use product.

APPLICATION

1. Shake the can well ap-prox. 30 times.

2. Remove small black lidfrom the top of the can.

3. Screw Sika® RoofBondcan into Spray ApplicationGun..

4. Apply the flat nozzle tothe end of the Spray Ap-plication Gun.

5. Sika® RoofBond isready to use. The amountof expanding foam can beadjusted by applyingmore or less pressure onthe trigger.

6. Apply Sika® RoofBonddirectly onto the surface,then quickly press the in-sulation panel onto theflat roof with light pres-sure and adjust. Use thespacer to ensure right dis-tance between the nozzleand a substrate.7. Apply the appropriateamount of Sika® Roof-Bond according to theroof wind-load zone re-quirements.

Sika® RoofBond must be applied according to the re-quirements of the wind-load zones. Wind load mustnot exceed 2,4 kN/m2.Advisable application of product:

Middle zone: 3 beads / m▪ Perimeter zone: 4 beads / m▪ Corner zone: 5 beads / m▪ On trapezoidal metal clad min. one strip per crown▪

CLEANING OF EQUIPMENT

Clean all tools and application equipment immediatelywith Sika® Boom Cleaner. If application gun is notcleaned properly, it will be blocked and unfit for nextapplication.
