Installation Recommendations

Deflex 446/c installation instructions

1. The base surface, to which the profile is supposed to be installed, must be even, smooth, free of any contaminants. After the surface is cleaned, the profile installation location needs to be primed (binding layer must be applied).

2. In order to even out the surface, it is necessary to create a base layer using epoxy resin (on both sides of the expansion joint) or using modified cement mortar, with a width of approx. 20-30 mm more than the support arms of the aluminium profiles.

3. The aluminium surfaces adhering directly to the floor level must be thoroughly cleaned, with the removal of any oils or fats, before installation.
Lay out the side profiles on the initially prepared epoxy resin or modified cement mortar layer, making sure that no air bubbles are created. Gently press the profile with a rubber hammer until evened out with the floor finish top surface.
The laid-out fresh resin or mortar layer must pass through the openings in the side support aluminium profiles. Top support surfaces must be cleaned of the fresh mass squeezed out this way.
Make sure the profile joints are level, so that equal height is maintained.

4. After the epoxy resin or modified cement mortar dries, anchor the profile and remove the installation 'beams'. Use anchors appropriate for the load values and surface type for the installation. Adhere to the recommendations of the installation anchor manufacturer.
Anchoring the profile must be made at a spacing of approx. 300 mm, and not closer than 50 mm and no farther than 150 mm from the edge of the aluminium profile. In case of an overlay profile, the recommended anchoring distance from the profile end edge is 150 mm. In order to install four running metres of profile, one needs approx. 30 anchors, which gives a use of 7,5 anchors for a running metre of expansion joint.

5. After the side profiles are mounted, install the elastomer inlay.
During installation, make sure that the inlay is installed with adherence to the dimension S (visible profile width on floor surface) - fig. 5.

1. The base surface, to which the profile is supposed to be installed, must be even, smooth, free of any contaminants.

2. In order to remove any possible unevenness, the undersides of the aluminium profiles should be covered with foam rubber, synthetic rubber spacers or a different permanently elastic material. It is important for the profile to adhere well and to rest on the support surfaces.
In case of dynamic loads (vehicle traffic) acting on the profile, support profiles should be embedded (glued) to the surface by using i. e. epoxy resin.

3. After the load bearing profiles are arranged properly, the lower surface may be installed (overlay installation using rawplugs).
There are conical openings in the aluminium profiles, spaced approx. 300 mm apart.In case of an overlay profile, an opening separation from the end edge of the profile of 150 mm is recommended. For the installation, use rawplugs and screws of stainless steel with conical cross heads.
For dynamic loads (vehicle traffic) acting on the profile, installation should be executed using installation anchors of galvanised stainless steel and conical head screws.
In order to install four running metres of profile, one needs approx. 30 anchors, which gives a use of 7,5 anchors for a running metre of expansion joint.

During installation, make sure that the inlay is installed with adherence to the dimension S (visible profile width on floor surface).
