Application steps

MIXING

SikaTop®-501 Seal powder in a clean mixing container. Add recommended amount of water while mixing with a 400-600 RPM mixer at least for 3-5 minutes until a homogenous and uniform mixture is obtained. After waiting for 3-5 minutes, mix again for approximately 30 seconds and it becomes ready to use.

APPLICATION

Apply SikaTop®-501 Seal with brush on the dampened substrate. When the first layer sufficiently cured apply the second coat. This period may change between 3 to 5 hours depending on environmental temperature. Application period between each layer must be less than 6 hours.

CURING TREATMENT

After SikaTop®-501 Seal application, material must be protected from losing its water rapidly. Do not use curing compounds. SikaTop®-501 Seal must be kept wet for 5-7 days. 

CLEANING OF TOOLS

Clean all tools and application equipment with clean water immediately after use. Hardened / cured material can only be removed mechanically.
