Joint Design
Joint width of between 10 mm and 35 mm. Minimum Joint depth of 10mm. Width-to-depth ratio of 2:1 for wall joints and 2:1,6 for floor joints.
Typical joint dimensions for joints between concrete elements:
| Joint distance | Joint width | Min. joint depth | Min. joint depth |
| Wall | Floor | ||
| 2,0 m | 10 mm | 10 mm | 10 mm |
| 4,0 m | 15 mm | 10 mm | 12 mm |
| 6,0 m | 20 mm | 10 mm | 16 mm |
| 8,0 m | 30 mm | 15 mm | 24 mm |
| 10,0 m | 35 mm | 17 mm | 28 mm |
All joints must be correctly designed and dimensioned in accordance with the relevant standards and codes of practice before their construction. The basis for calculation of the necessary joint widths are the type of structure, dimensions, technical values of the adjacent building materials, joint sealing material and the specific exposure of the building and the joints.

Calculation:
Metre run = Packaging Volume / Joint width (mm) x Joint depth (mm)
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.
SUBSTRATE PREPARATION
The substrate must be sound, clean, dry and free of all contaminants such as dirt, oil, grease, cement laitance, old sealants and poorly bonded paint coatings which could affect adhesion of the adhesive / sealant. The substrate must be of sufficient strength to resist with the stresses induced by the sealant during movement.
Removal techniques such as wire brushing, grinding, sanding or other similar mechanical tools can be used.
All dust, loose and friable material must be completely removed from all surfaces before application of any activators, primers or adhesive / sealant.
Sikaflex®-134 Bond & Seal adheres without primers and/or activators.
However, for optimum adhesion, joint durability and critical, high performance applications the following priming and/or pre-treatment procedures must be followed:
Non-porous substrates
Aluminium, anodised aluminium, stainless steel, PVC, galvanised steel, powder coated metals or glazed tiles, slightly roughen surface with a fine abrasive pad. Clean and pre-treat using Sika® Cleaner P or Sika® Aktivator-205 applied with a clean cloth.
Before bonding / sealing, allow a waiting time of > 15 minutes (< 6 hours).
Other metals, such as copper, brass and titanium-zinc, clean and pre-treat using Sika® Cleaner P or Sika® Aktivator-205 applied with a clean cloth. After a waiting time of > 15 minutes (< 6 hours). Apply Sika® Primer-3 N by brush.
Allow a further waiting time of > 30 minutes (< 8 hours) before bonding / sealing,
PVC must be cleaned and pre-treated using Sika® Primer-215 applied with a brush.
Before bonding / sealing, allow a waiting time of > 15 minutes (< 8 hours).
Porous substrates
Concrete, aerated concrete and cement-based renders, mortars and bricks, prime surface using Sika® Primer-3 N applied by brush.
Before bonding / sealing, allow a waiting time of > 30 minutes (< 8 hours).
Note: Primers and activators are adhesion promoters and not an alternative to improve poor preparation / cleaning of the joint surface. Primers also improve the long term adhesion performance of the sealed joint.

CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Remover-208 immediately after use. Once cured, hardened material can only be removed mechanically. For cleaning skin use Sika® Cleaning Wipes-100.
