Optimum heat transmissionfor new buildings & renovationThe STRONGBOARD FL element is a polyester fi breboard with a high proportion
of aluminium, laminated fl eece and thermoplastic binders with high tensile and
compressive strength. Due to the low weight of 4.9 kg per m², it is also suitable in
static sensitive constructions. As a load distribution layer, STRONGBOARD FL is used
for tile coverings and for fl oating laminate fl oorings
The result: The good thermal conductivity ensures rapid transport of heat into
the room.

Laying of additional insulation and heating elements
Laying instructions
If possible, screw the support batten indoorways to the substrate. This eases theinstallation of transition rails.
Adhere panels full-surface to the ground anduse max. one insulation layer. Only use fullpanels in doorways.
Begin with the head or side elements. Headelements with aluminium are recommended inorder to improve pipe installation.
Glue elements fully onto insulation/ground. Apply the adhesive (MAPEI Ecofix) thinly and allow the water to evaporate completely.
Fix edge insulation strips on the wall. Ends mynot overlap. Pay attention to the height of theoverall construction.
Lay insulation panels. Place panels in a staggeredbond, i.e. with offset-joints and crosswise to thelater laying of IDEAL elements.
When using blanc cuts, pay attention that theprofi led fold stays intact and always fi ts tightlyagainst each other.
Laid surface of the System IDEAL EPS – Until the STRONGBOARD FL elements are laid,use e. g. insulation panels as routes to protect the system from compression.
Push system pipe in huge arcs and stress-freefrom above into the pipe channels.

Laying STRONGBOARD FL
Laying instructions
The fixation attains an optimum adherenceafter air drying. Lay the elements and pressfirmly.
A tension-free installation is to be observed forsurfaces completely laid using STRONGBOARD FL.
Fix the STRONGBOARD FL to the heatingelements with adhesive, e.g. Ecofix from MAPEI, across the whole surface in case of tile coverings.
Apply Ecofix thinly and allow to air dry. Afterthe water has completely evaporated, theadhesive adheres and turns dark yellow.
Laying is performed as an English bond. The joint offset must be greater than 20 cm – cross joints are not permitted.
The cutting of the panels can be performedusing commercially available circular saws,plunge-cut saws or jigsaws.
Place smaller pieces into the second-last rowfor improved load distribution. Maintain thebond.
Protect the finished surface from soiling, adequately cover walkways e.g. using insulation panels.The surface floor can be laid directly.
In case of tile coverings, cover the butt joints using a joint adhesive tape. The tape must not overlap.

Laying tiles on STRONGBOARD FL
Laying instructions
Joint the tiled area at the latest after 24 hours with approved jointing material.
Lay tiles in buttering-floating procedure wit-hout cavities onto the prepared substrate.
After insertion, press down tiles firmly and adjust. The adhesive bed thickness must then total at least 4 mm.
Maintain joint widths; up to 30 x 30 cm at least 3 mm, up to 40 x 40 cm at least 4 mm and up to 80 x 80 cm at least 5 mm.
Mix approved tile adhesive and apply as a contact layer onto the substrate.
Create ridged surface depending on the tile size; from 10 x 10 cm to 30 x 30 cm: 8 mm notched trowel, up to 80 x 80 cm: 10 mm notched trowel.
Apply approved tile adhesive onto the rear side of the tile, also across entire surface and with small ridges.
The waiting times for entering the surface and the commissioning of the floor heating must be observed in accordance with the manufacturer‘s instructions.
After setting of the joint mortar, clean the tiles diagonally to the joint.
! Only lay tiles in combined procedures (buttering-floating) with MAPEI Elastorapid and Ultra-color Plus or Sopro megaFlex S2 turbo (MEG 666) and Sopro DF 10® / Sopro DF 20®!
