−25 °C to +70 °C (dry)
Joint design
The joint dimensions must be designed to suit the movement capability of the sealant. The joint width must be ≥ 10 mm and ≤ 15 mm. A width to depth ratio of 2:1 must be maintained (for exceptions, see table below).
Typical joint dimensions
| Minimum joint width [mm] | Minimum joint depth [mm] |
| 10 | 10 |
| 15 | 10 |
Triangular joint profiles must have sides for bonding ≥7 mm.
For larger joints, contact Sika Technical Services for additional information.
Application
Sag flow
| < 1 mm (+23 °C) | (ISO 7390) |
Ambient air temperature
+5 °C min./+30 °C max.
Substrate temperature
+5 °C min./+30 °C max. Minimum +3 °C above dew point temperature
Curing rate
| ~4 mm/24 hours (+23 °C / 50 % r.h.) | (CQP* 049-2) * Sika Corporate Quality Procedure |
Skinning time
| ~45 minutes (+23 °C / 50 % r.h.) | (CQP 019-1) |
Consumption
| Joint length [m] per 280 ml | Joint width [mm] | Joint depth [mm] |
| 2,8 | 10 | 10 |
| 1,8 | 15 | 10 |
Consumption calculation formula
Length of joint [m] = 280 ml / (Joint width [mm] x Joint depth [mm])
Litres / Metre run of joint = (Joint width [mm] x joint depth [mm]) / 1000 [m x mm2 / l]
Consumption depends on the roughness and absorbency of the substrate.
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
APPLICATION INSTRUCTIONS
SUBSTRATE PREPARATION
The substrate must be clean, dry, sound and free from oils, grease, dust and loose or friable particles. Sikacryl®-112 Universal adheres without primers and/or activators. For porous substrates, e.g. concrete, plaster and / or wood, Sikacryl®-112 Universal can be dissolved in water (1:1 to 1:5 ratio) and used as a primer if necessary. On plastics and paints, adhesion tests must be carried out prior to application. Iron and steel must be protected with an anti-corrosion primer.
