Sikalastic®-618 is a one-component, cold applied, moisture-triggered polyurethane membrane. It cures to form a seamless and durable waterproofing solution for exposed roof areas and structures.

Single component - No mixing, easy and ready to use
Cold applied - requires no heat or flame
Seamless membrane
Compatible with Sika® Reemat Premium - easy to detail
Easily recoated when needed - no stripping required
Economic – provides a cost efficient life cycle extension of failing roofs
Vapour permeable - allows substrate to breathe
Elastic - retains flexibility even at low temperatures
Good adhesion to most substrates – see table
Fast curing - Free from rain damage almost immediately on application

Usage

For roof waterproofing solutions in both new construction and refurbishment projects
For roofs displaying complex detail areas, even when accessibility is limited
For cost efficient life cycle extension of failing roofs

Pot Life

Sikalastic®-618 is designed for fast drying. High temperatures combined with high air humidity will increase the curing process. Thus, material in opened containers should be applied immediately. In opened containers, the material will form a film after 1 hour approx. (+20 °C / 50 % r.h.)

Waiting Time / Overcoating

Ambient conditions	Minimum waiting time*
+5 °C / 50 % r.h.	18 hours
+10 °C / 50 % r.h.	8 hours
+20 °C / 50 % r.h.	6 hours
+30 °C / 50 % r.h.	4 hours

*After four days the surface must be cleaned and primed with Sika® Reactivation Primer before continuing.

Note: Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

Applied Product Ready for Use

Ambient conditions	Rain resistant*	Touch dry	Full cure
+5 °C / 50 % r.h.	10 minutes	10 hours	19 hours
+10 °C / 50 % r.h.	10 minutes	6 hours	10 hours
+20 °C / 50 % r.h.	10 minutes	4.5 hours	6 hours
+30 °C / 50 % r.h.	10 minutes	2 hours	4 hours

*Be aware that impact of heavy rain or rain showers can physically damage the still liquid membrane.

Note: Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
