Application
Substrate moisture content
Dry or matt damp. Do not apply in construction joints when standing water is existing.
Ambient air temperature
+5 °C min.
For installation below +5 °C ambient temperature, special measures are required in accordance with relevant national regulations and Sika guidelines
Substrate temperature
+5 °C min.
For installation below +5 °C substrate temperature, special measures are required in accordance with relevant national regulations and Sika guidelines
SUBSTRATE QUALITY
The substrate must be sound, clean, dry or matt damp, free from all surface contaminants
SUBSTRATE PREPARATION
Existing Concrete
All loose particles, release agents, laitance, paint, rust and other poorly adhering materials must be removed by suitable hand or mechanical preparation.
Freshly cast concrete
During concreting, compact well around SikaSwell® A profiles to provide a dense concrete without any honeycombing or voids.
Surfaces which are excessively rough can be susceptible to leaking. It is recommend to smoothen the freshly cast concrete with a batten where the sealing profile is to be placed.
