FIBRE REINFORCED, ONE PART POLYURETHANE ELASTOMERIC ANTI-ROOT MEMBRANE

Surface Preparation:
Concrete surfaces must be float or shutter finished. The surfaces must be free of cavities and projections. Blockwork or brickwork must be flush pointed and of a uniform finish.

The surfaces should be made dry, clean, dust and frost free to expose a sound, clean substrate.

Priming Application:
Priming is not normally necessary on good quality concrete, however for particularly porous or metal surfaces, SpECtite PAR800 Primer must be used.
SpECtite PAR800 should be applied after the primer has become touch dry, usually 2-4 hours following application, but before it has fully reacted.
If the SpECtite PAR800 is not applied within 48 hours after priming, the surfaces should be re-primed.

Application:
The quantity of material used per coat may vary depending on the porosity of the substrate and the surface profile.

Apply the first coat and allow it to become tacky.

Apply the SpEC Geotextile and gently roll into the tacky first coat using a ribbed steel roller. Once the first coat is touch dry, apply the second coat at right angles to the first coat to ensure and even coating application.

SPRAY APPLICATION:
• Only airless spray should be used
• Graco King 60 to 1 ratio or similar
• Compressor:- 100 psi, 60 cfm min
• Tip Size:- 28/30 thous. 50° angle
