APPLICATION
IMPORTANT
SikaTop®-107 Seal Plus IN may display signs of “blooming” after rain or in damp weather. This does not affect the performance of the coating in any way.
IMPORTANT
Do not apply in direct sun and/or strong wind.
IMPORTANT
In areas of severe water penetration, three coats might be required.
IMPORTANT
Protect freshly applied material from freezing conditions, rains etc.
Detailing

Note: If the second coat is applied 12 hours or later to first coat, the first coat shall be slightly pre-wetted by using a fine spray.
IMPORTANT
Slight fabric marks may be visible after application of the second coat, but it will have no adverse bearing on the performance of the waterproofing system.
Protection
CURING TREATMENT
Cure SikaTop®-107 Seal Plus IN for minimum 7 days to ensure full cement hydration and minimise cracks. Use wet hessian cloth, spray curing or similar approved methods during the recommended period of curing.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
