Materials
PVC
Novojunta® 3 is a prole made by coextrusion of PVC-P (rigid PVC) and PVC-U (exible PVC). PVC-U
allow the prole to absorb expansion and contraction movements from oor and wall tiling where is
installed and PVC-P is suitable, due to its rigidity, to the support of the tile.
El PVC (polyvinyl chloride), is a polar amorphous thermoplastic polymer highly resistant to abrasion,
corrosion and a wide range of chemical products. Has a good resistance to impact, low water absorption,
low electrical conductivity and is dimensionally stable.
Tips of installation
According to our experiencie and our collaboration with specialized companies, we recommend the
following:
- Outdoors: it is recommendable to close areas between 107,6-269 ft
2
(10-25 m
2
) maximum and a
distance between expansion joints not exceeding 16,4 ft (5 l.m.)
- Indoors: it is recommendable to close area up to 430,4 ft
2
(40 m
2
) max. with a distance between
expansion joints not exceeding 26,2 ft (8 l.m.). If the ooring is dark and is under direct insolation, it will
be recommendable to apply the same tips than in outdoor oorings.
You will also need to take into account about the critical points of the installation:
- Take into account the structural joints.
- Install expansion joints:
- Between different materials (orientation, color, etc.)
- In different kinds of supports.
- In joints with constructive elements, narrowing or height changes.
- In perimeters when areas are bigger than 75,3 ft

1. Spread a big amount of gripping material on the surface where the pavement will be installed.
2. Then, place the prole and press it to allow the gripping material pass through the mechanized holes
on the xing wing.
3. Place a tile on the xing wing of the prole and press to an optimal contact with the gripping material.
4. Repeat the previous step placing tiles along the prole until the installation is nished.
5. Before curing, tap with a rubber hammer to align the prole with the pavement.
6. Finally clean the remaining material and let dry.
* If you planned polishing the soil, install the prole slightly below the tile to avoid possible damages.
