Sika Black Jack 902 Bitumen and Flashing Primer is a thin black primer used to give a key before applying bitumen paints, roof coatings and flashing tape systems. It helps prepare suitable surfaces so bituminous coatings and flashing products can bond more effectively.

The 1 litre tin is suited to small roof preparation jobs, localised flashing work, patch repairs, edge detailing and priming smaller areas before applying compatible bitumen-based products. It can be used on suitable concrete roofs and floors, cementitious screeds and renders, bitumen felt, asphalt, mastic, wood, and weathered corrugated iron or steel.

What This Product Is Used For

This primer is used where a surface needs preparing before a compatible bitumen paint, roof coating or flashing tape is applied.

• Priming suitable roof surfaces before bitumen coatings.
• Preparing concrete roofs, floors, cementitious screeds and renders.

Why Choose This Bitumen Primer

Choose Sika Black Jack 902 when the job needs surface preparation before applying a bitumen paint, roof coating, flashing tape or other compatible bituminous system. It is not the main waterproofing coat itself; its job is to improve the surface key so the following product has a better prepared base.

The 1 litre size is especially useful where only a small amount of primer is needed, such as around roof details, repair areas, edges, gutters, flashing joints, felt repairs or localised coating work. For larger roof areas, calculate coverage against surface porosity before ordering.

How It Fits Into The Job

Use this primer after the surface has been inspected, cleaned and prepared, but before the final bitumen coating or flashing product is applied.

• Step 1: Remove dirt, dust, grease, loose material, rust, moss and green growth from the surface.
• Step 2: Make sure the surface is dry, stable and free from standing water, frost or loose contamination.
• Step 3: Repair cracks, holes, loose felt or damaged areas before priming where required.
• Step 4: Stir thoroughly before and during use. Do not thin the primer.
• Step 5: Apply a thin, even coat by brush or spray, avoiding ponding or pooling.
• Step 6: Allow the primer to dry before applying the compatible bitumen coating, roof coating or flashing tape system.

Quick Use Guide

Good preparation is important because primers work best when the surface is clean, stable and suitable for the coating system being applied afterwards.

• Use on dry, stable and cleaned surfaces only.
• Stir before use and during application.
• Apply by brush or spray.
• Do not thin the primer.
• Avoid heavy pooling, especially when spraying.
• Clean tools immediately after use with suitable wipes or white spirit.
