Sika® Hybriflex® SMP

High modulus hybrid flooring joint sealant

Sika® Hybriflex® SMP is a one part, chemically curing sealant and adhesive combining the best qualities of silicone and polyurethane technologies. It is specifically designed as a multi purpose floor and wall grade for all concrete saw cuts and cladding applications and/or slab expansion joints, where abrasion resistance is required.

  • Excellent trafficking resistance.
  • Good slump resistance - suitable for wide joint applications (up to 65 mm).
  • Abrasion resistant.
  • Excellent resistance to chemicals and petrol (10 % dilute acids, alkalis, most solvents).
  • Good flexibility (Butt Joints ±25 %, Lap Joints ±25 %).
  • Overpaintable with most paints (compatibility test should be made).
  • Can be applied on damp surfaces.
  • Durable anti pick formulation for joints subject to idle tampering and acts of vandalism where traditional sealants may be more easily damaged or removed.

Usage

Large expansion joints for:
  • Stadia.
  • Floors.
  • Warehouses.
  • Factory floors.
  • Sports arenas.
  • Shopping centres etc.
  • Secure environments where a tamper-resistant sealant may be required e.g. prisons & secure units (supervised or hard-to-reach areas).

Application steps

SUBSTRATE PREPARATION

All surfaces must be cleaned and be free from dust, grease and frost. Surfaces may be damp, but must have no standing water. For some substrates, priming is not required (except when area is intermittently or permanently immersed). If in doubt contact Sika® Technical Services.
Joints should be designed in accordance with BS 6093. Square cross sections are preferred with a minimum
10 mm depth.

NEW JOINTS: Concrete joints should be sawn, all debris flushed away after cutting, and joints allowed to dry.
RENOVATING OLD JOINTS: Remove all old sealant from existing joint and clean back to sound concrete by wire brushing, grinding or shot blasting.

Fit backing rod and/or joint breakers as required by relevant flooring standards/specifications/codes of practice.
For a neat finish, mask joint edges, removing masking tape immediately after tooling is complete and before sealant skins over.

Primer
Mortar: Use Sika® Primer 3-N.
Improve adhesion to non porous surfaces by using Sika® Aktivator 205.
