POLYFLEX PU

APPLICATION TIPS

 

For all flooring types, we are talking about an ideal application temperature of 20-25ºC, on decent substrates. Deviations from these admissions might vary the consumptions/times/sequence of layers/preparation work and the final result in general.


The system is described in detail in the TDS of the materials involved.

 First make sure the substrate is as good as possible (stable, clean, flat), applying, if needed, two ELASTOSPORT layers on the substrate before placing the ISOPOL rolls (see SPORTFLEX-EX system) . This would be needed on asphalt substrates and not on concrete screeds. Then place the ISOPOL rolls on the floor in their final positions without gluing them. Lift each side of each roll and apply the PU glue by either notched (toothed) trowel with 3mm teeth (better and recommended) or by flat (straightedge) trowel and then glue the rolls immediately without waiting. In case there are small bulges (humps, swollen parts) on the ISOPOL after its application, you’ll have to tear it around the edge of the hump without removing it completely (with a knife or something), raise that small part, put some PU glue underneath and glue the hump part again, making sure this time it’s flat. Then you let everything dry.

Do not overlap the rolls but bring them as close together as possible to eliminate gaps. If you use the notched trowel (which we strongly recommend), do not put any weights on the edges or anywhere else, it’s not needed. You could always use a light cylinder (10-15kg maximum) to compact the rolls on the floor right after gluing, especially if you use the flat trowel for the glue.

After the ISOPOL rolls are glued on the surface and at their joints one next to the other in a tight way (without overlapping), it is recommended that the joints (only) are covered flush with ELASTOTURF (or PU FLEX 140) with a flat trowel (or a brush) along their whole length, so that the surface is leveled out. Next day the joints are ground lightly with sandpaper or other grinding device to smooth out the joints with the rest of the surface and create the required roughness, and then ELASTOTURF layers are laid as usual over the whole surface.

*** In case there is rain while gluing, the hardening of the glue will be compromised and the gluing process will have to be repeated. In case there is rain after the ISOPOL rolls have been glued, you’ll have to allow for the water absorbed into the rolls to dry out before covering with the subsequent materials


POLYSPORT STUCCO 950

Application temperature:
15 to 35º C

Working temperature of applied material:
-30 to 60º C

Tools of application:
flat metal trowel

Consumption (20-25º C):
700 gr/m² on power-troweled industrial floors in two layers

Time between layers:
3-5 hours, depending on the ambient conditions (temperature, air dryness)

Covering of POLYSPORT STUCCO: usually next day.

 

POLYSPORT PU 951

Application temperature:
15 to 30º C

Working temperature of applied material:
-30 to 60º C

Tools of application:
notched trowel with 4-5 mm notches in one layer -consumption (20-25º C): 2-2.3 kg/ m² (followed immediately by spiked roller over the surface to kill the air pockets and level out the surface)

Covering or POLYSPORT PU 951:
next day

POLYSPORT MAT 952

Application temperature:
10 to 30º C

Working temperature of applied material:
-30 to 60º C

Tools of application:
mohair paint roller with short hair.  Two layers needed, "dragged" on the floor

Consumption (20-25º C):
150-200 gr/m² on the self-leveling layer of POLYSPORT PU 951

Time between layers:
3-5 hours, depending on the ambient conditions (temperature, air dryness)

3 people will be needed for 4 days for a surface of 500 m², plus one day at least for ISOPOL (shock-pad) installation, usually two days

1st working day (10 hours):
Application of the pore filler (POLYSPORT STUCCO 952) over the whole surface
2nd day: Application of the self-leveling POLYSPORT PU 951 over the whle surface
3rd day: Application of the mat sealer POLYSPORT MAT 952
On the second day of application, one additional worker will be needed to help carry around the ready-mix of the self-leveling POLYSPORT PU 951.

*If extensive repairing will be needed, times will be affected accordingly
*In all cases, the substrate is considered to be a decent power-troweled one.

Make sure that you sand the floor thoroughly before the application of the self-leveling POLYSPORT PU 951.  Before applying the POLYSPORT 952 varnish make sure you check the surface of POLYSPORT PU 951 for local trapped air bubbles, that you will have to burst first and then repair locally with POLYSPORT PU 951 using a small metal trowel
