What is a contact adhesive? Deep Dive into Tremco’s SF115 Contact Adhesive

Rejoice Chikosi / 02 February 2024

When talking about adhesives, contact adhesives are a key bonding solution for a wide range of floor solutions. When applied they form a strong bond between the two surfaces. Tremco’s SF115 Contact Adhesive, is a single part, modified elastomer contact adhesive. Tremco SF115 Contact Adhesive is suitable for horizontal and vertical surfaces applications. The Tremco SF115 is specially formulated for use with a wide range of flooring solutions including rubber, vinyl sheet, PVC skirting, cork, cap, and coving.

Understanding Contact Adhesives:

Contact adhesives are generally applied using a ‘V’ notched trowel and allowed to dry before application. With some rubber floor coverings, it is recommended that the adhesive is applied to the floor with the ‘V’ notched trowel and to the back of the rubber with a flat spreader. For vertical surface, a bristle brush application may be convenient. This enables a strong bond to form between the two surfaces. Always refer to the floor finish manufacturers installation instruction.

Tremco’s SF115 Contact adhesive is ideal in those difficult situations where a normal adhesive is unsuitable, which sets it apart from alternative adhesives. It adheres well to non-porous surfaces and can also be applied directly to dry (Below 75%RH) concrete and sand and cement which are fully cured and free from laitance. Subfloor which are above 75% RH or have no structural Damp Proof Membrane must incorporate a suitable Tremco Surface Damp Proof Membrane.

Tremco’s SF115 contact adhesive has the following key benefits:

  1. Extra strong bond: SF115 creates a robust bond that stands the test of time. Its strength and durability make it a reliable choice for projects that demand a long-lasting and secure adhesive connection.
  2. Extended working life: Critical for projects that require precision and alignment, long working life means installers have the flexibility to ensure correct install before the adhesive starts setting.
  3. Suitable for the widest range of floor coverings: Whether you're working with wood, laminates, rubber, or metal, skirting, cap and coving SF115 demonstrates excellent compatibility across a range of materials. This versatility enhances its usability in diverse settings.
  4. Fast drying but long ‘open time’: Ensuring quick and efficient bonding. This makes it a time-saving solution for projects that require a speedy turnaround.
  5. The dry bond does not support combustion: SF115 excels in applications where heat resistance is essential. This makes it suitable for use in environments where temperatures may fluctuate.
  6. Ease of Application: SF115 is user-friendly, allowing for easy application with a trowel, flat spreader, or bristle brush. Tremco SF115 consistency ensures a hassle-free process, enabling professional installers to achieve optimal results.
