he core of our products (Polystyrene) as well as the protective coat (polymer-quartz mass) are flexible materials, which is why it is very important to use installation materials which remain flexibile over a wide temperature range.
We recommend the use of flexible adhesives used for embedding and spackling fiberglass mesh for insulation systems, for example:
In place of the above mentioned adhesives, can also be used polyurethane foams for facade, such as:
During adhesive bonding, larger and heavier elements can be fastened mechanically. (strips, nails, screws, etc…)
a) While gluing elements to the base, on contact area of two elements apply permanently flexibile adhesive - sealant (Ceresit CT84). It is recommended to leave an appropriate gap (0,5-0,8 cm) between profiles in order to fill effectively the empty space between two profiles (see picture 1, 2, 3).

b) When dry, glue seam must be cleaned (see picture 4,5,6) and then primed to provide better adhesion for the repair compound (spatula)(see picture 7,8).

c) After permanent immobilization of glued components (adhesive bonding on the base), the contact edges of elements with a wall, especially the horizontal section should be joined with permanently flexibile sealant. It prevents water infiltration under profiles and the formation of damp patches on the wall.
Recommended adhesives - sealants:
Joint sealant StoSeal F505
After the primed section is dry fill the joint with repair mass WMB (See picture 9,10,11).

On the next day, or after about 6-8 hours the joint can be polished and after that put again repair mass. High humidity can extend the drying time of the repair mass (see picture 12, 13, 14).

After the installation is finished it is necessary to paint the stucco elements using appropriate compatible with our products facade paint.
Make sure that the surface is clean, dry and dust free.In case of poor weather conditions we recommend waiting 12 hours so the stucco can be completly dry before any paint coatings are applied.Pay Attention: We do not recommend priming of our products.
In the construction field there are at least two basic types of substrates:
Choose an appropriate paint to the surface!
Recommended paints:
For possible negative effects (cracks, scratches and similar) of paints, spatulas and adhesives other than the above mentioned the WMB company does not take responsibility.

We strongly recommended not using silicate paints.
These paints can enter in chemical reactions with the base and can irreversibly damage the polymer quartz coat of our products.
It is forbidden to use solvent-based paints.
One of the most important technical parameters of paints is the reflection coefficient of scattered light-HBW. For white color HBW = 100, for black HBW = 0. If color is darker, the value of HBW is lower.
Painted elements in dark colors absorb much more sun rays than elements painted in light colors, that leads to excessive heat and the formation of large thermal stress and causes of cracks in the layer of paint and sometimes also in the base.
We strongly recommended not using of dark colors for which the coefficient HBW is smaller than 30.
During installation respect the technical guidance of manufacturers and materials used. Such information can be found on the packaging of these materials and their technical data sheets. In case of doubts, consult with your materials dealer or technical adviser of the brand.
