Double-sided foam tape Deka D-300-0050 19 mm × 5 m — foam adhesive tape for mounting and sealing

Deka D-300-0050 double-sided foam tape, 19 mm × 5 m, is a foam adhesive tape designed for bonding, sealing and mounting lightweight materials. The closed-cell foam core provides conformability to uneven surfaces and gap-filling capabilities, while adhesive layers on both faces enable secure attachment to a variety of substrates. The product is intended for indoor applications in construction, finishing work, mounting trims and signage, as well as general repairs where a thin, flexible bonding solution is required.

Advantages

The foam construction delivers cushioning and compensates for minor irregularities, improving contact between bonded surfaces. Dual-sided adhesive offers immediate tack and reduces the need for mechanical fasteners in many light-duty installations. The tape’s narrow width and roll length make it easy to cut to size and apply in confined areas. It provides a discreet, low-profile bond that resists movement in typical indoor conditions.

Suitable for

• Mounting lightweight trims and profiles
• Sealing gaps around frames and panels
• Attaching signs, nameplates and decorative elements
• Repairing loose fittings and small fixtures
• Fixing lightweight materials to painted, coated or smooth surfaces

Key specifications

• Width: 19 mm
• Length: 5 m
• Material: closed-cell foam core with adhesive on both sides
• Function: double-sided bonding, sealing and gap-filling
• Suitable environment: indoor use

How to use

Prepare surfaces by cleaning them of dust, grease and loose particles; ensure surfaces are dry and free from coatings that could prevent adhesion. Cut the required length of tape and apply the adhesive side firmly onto the primary surface, pressing along the tape to ensure full contact. Remove the protective liner from the exposed adhesive side and press the mating surface into place, applying consistent pressure to achieve an even bond. Allow the assembly to settle without disturbance for a short period to reach initial tack.

Usage recommendations

For best results, use at typical room temperatures and on smooth, dry surfaces. Avoid application on damp, dusty or highly textured substrates. For heavier loads or outdoor exposure, supplement with mechanical fasteners or choose a product rated specifically for outdoor and structural applications.
