Which is better Dekaseal or Sikaflex?
Dekaseal 8936 is a better product than Sika Lastomer 710: it has a higher viscosity, is very easy and quick to dab and has a lower water vapour permeability. It also pulls fewer threads when applied. However, Sika has launched a new product on the market: Lastomer 514. Lastomer 514 is equivalent to Dekaseal 8936.
Which Dekaseal for what?
Dekaseal 8936 is only for applications where mechanical fasteners (such as screws) are also used. Examples: Service hatch, lights, socket, skylight, etc.
Dekaseal 1512 can be used as a general sealant. It can be used, for example, for skylights, hole penetrations in the floor, general sealing in the floor or for placing side walls on the floor.
Which Dekaseal for sealing?
This depends entirely on what you want to seal. Dekaseal 8936 is ideal for use with screws. For sealing without screws, we recommend the use of Dekaseal 1512 or a Dekasyl product.
What is Dekaseal 8936?
Dekaseal 8936 is a self-swabbing sealant based on so-called polyisobutene (similar to butyl). Polyisobutene-based sealants have the lowest water vapour permeability and are therefore excellent for sealing structures that are also mechanically fastened and for preventing water leaks.
How long does Dekaseal 8936 need to dry?
Dekaseal 8936 can be removed immediately after application. However, it is advisable to wait 1-2 hours, as more solvent will have evaporated by then. It dries only by evaporation of the solvent. If you wait a little, it also pulls fewer threads. Tip: It is also a good idea to allow everything to air dry.
However, the vehicle can be moved again immediately after applying Dekaseal.
What is the shelf life of Dekaseal 8936?
At least 2 years.
When to dab decalin?
Dekaseal 8936 can be dabbed on for applications that are also mechanically attached in the visible area, e.g. side panels. It is recommended that you first cut or push with a plastic card or knife next to the processing area so that no Dekaseal is removed from under the joint when dabbing.
How much Dekaseal for roof windows?
For a 40×40 roof window you need about 220 ml Dekaseal. Care should be taken to use enough Dekaseal. In addition, the part should be squeezed out after use to ensure that it is completely sealed and watertight.
