FLEXFLOOR-EX 

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.

 

You have to make sure there is no rising moisture in the substrate of the flooring system, which will compromise the drying process of the materials involved (e.g. by emulsifying acrylic materials like top-coat ELASTOTURF 851) or the performance of the dried materials by exerting from underneath vapor or water pressure on them (creating for instance the danger of local swelling of the applied ELASTOTURF 851 top coat).

In case there is rain while a layer is not sufficiently dry, it will be probably have to be laid again or complemented somehow in order to restore the washed-away material. In case there is rain after a layer had dried sufficiently and before the next one, the surface will have to be left  to drain the rain water and get completely dry again completely before proceeding. A layer of ELASTOTURF is considered dry when its surface is not sticky any more (finger test).


1. On dry asphalt (or dry waterproof non-polished concrete, preferably after light grinding to provide grip and “bite” Flexfloor-Exf concrete) surfaces ELASTOCOAT 841 or SUPERELASTOCOAT 842 applied by squeegee

 

 

RITIVEX 1102 ACRYLIC PRIMER

Application temperature:
10 to 30º C

Working temperature of applied material:
-30 to 50º C

Tools of application:
squeegee or brush

Consumption (20-25º C): 
0.2-0.25 kg/m²

Covering in maximum 1 hour
 

ELASTOCOAT 841

Application temperature:
10 to 30º C

Working temperature of applied material:
-30 to 50º C

Tools of application:
Single-rubber-edge squeegee (75 cm length recommended)

Consumption (20-25º C):
At least 1.3 kg/m² for up to 2 mm thickness in 2 layers at least. Three layers are recommended

Covering of the first (or second) layer with the next ELASTOCOAT layer: next day
Covering with ELASTOTURF: next day after the last ELASTOCOAT layer 

or

SUPERELASTOCOAT 842

Application temperature:
10 to 30º C

Working temperature of applied material:
-30 to 50º C

Tools of application:
Single-rubber-edge squeegee (75 cm length recommended)

Consumption (20-25º C):
At least 1.3 kg/m² for up to 2 mm thickness in 2 layers at least. Three layers are recommended

Covering of the first (or second) layer with the next SUPERELASTOCOAT layer: next day
Covering with ELASTOTURF: next day after the last SUPERELASTOCOAT layer

Note that in case the surface is flat and smooth (as it should be), there is no need to have  intermediate ELASTOSPORT layers between the substrate and the ELASTOCOAT or SUPERELASTOCOAT layers. In case the substrate is not smooth enough (which happens regularly in real life), there will be a need for at least two intermediate ELASTOSPORT layers for smoothing (applied in the usual way, with the usual consumption-see SPORTFLOOR-EX system) before the application of the ELASTOCOAT or SUPERELASTOCOAT layers. In the case the surface is concrete, it will need grinding (by mosaic machine) or broadcasting of quartz sand between layers of RITIVEX primer, to create adequate local grip for the materials to be applied on top.


ELASTOTURF 851

Application temperature:
10 to 30º C (for outdoor areas, in the hottest summer days, early morning hours-or late evening hours-are preferred for application. Noon or early afternoon hours-or in general hours when temperature is rising- should be avoided for application)

Working temperature of applied material:
-30 to 50º C

Tools of application:
Single-rubber-edge squeegee (75 cm length recommended)

Consumption (20-25º C):
2.5 kg/m² for 1-1.5 mm thickness in 3 layers at least
Covering of the first (or second) layer: in 3-5 hours
Covering with ELASTOMARK 818: 10-12 hours after the last layer of ELASTOTURF or next day

Alternatively, ELASTOTURF can be applied by spotty roller in one layer (with 2.1 mm spots or so)-followed immediately by spiked roller over the surface to kill the air pockets and level out the surface-but it will be harder to apply.

 

Additional tips:
The RITIVEX layers and the two layers of ELASTOCOAT or SUPERELASTOCOAT could be applied in a single day if needed, early morning and late afternoon or evening hours preferably, with at least 3-4 hours between the two ELASTOCOAT or SUPERELASTOCOAT layers (in case there is a need for quartz sand broadcasting between RITIVEX layers it will take a bit more). The two layers of ELASTOSPORT (if needed) can be applied same day as the RITIVEX layers, in two equal-consumption layers by squeegee. ELASTOTURF in 3 layers will follow next day after the second ELASTOCOAT or SUPERELASTOCOAT layer to let the last ELASTOCOAT 841 or SUPER-ELASTOCOAT 842 layer dry sufficiently. Water addition in ELASTOTURF (concentrated or not) should be 5-8% and it’s better that the final layer of ELASTOTURF will have less water content (around 5% or so), to have better coverage. Again, any ELASTOTURF layer can be covered after 3-5 hours with the next one. Next day ELASTOMARK will be applied for marking (optional). For example, for a basketball court around 10 kg of ELASTOMARK are needed.

● The squeegee should be dragged along to follow smoothly the contour of the surface, not too hard (to avoid “hick-ups” of the squeegee or blocking of its movement), not too soft (to avoid leaving excessive material in places)
● ELASTOTURF should be applied in a meandering way, beginning from one edge of the area, going down to the other edge in one squeegees strip, then turning back on the opposite direction overlapping the previous strip by 20-30 cm or so and continuing the same way. Possible traces of the squeegee edges will have to be smoothed out with the squeegee or other tool (e.g. trowel). In any case, those traces tend to be eliminated after the area is put in use
●For better aesthetic result and consumption control, after the first and second layers of ELASTOTURF 851 have been applied, it is important to cut off any excess 853 material protruding from the surface, bulges or humps by sanding or by straightedge (flat) small metal trowel (with handle or not).
● In any case, rain will compromise the drying process and the integrity of any applied layer that has not dried out. After application of the final layer, ELASTOTURF has to stay at least 3-4 days to dry completely before being given to use. If there is rain before this drying-out period, it should be ensured that at least no standing water stays on the surface, to avoid emulsification of the acrylic topping. Besides, rising humidity will always compromise the drying and stability of the system and its component layers


Besides, note that the first layer of ELASTOTURF 851 will consume more material than the following layer because of filling in the irregularities, small holes, cavities etc. of the ELASTOCOAT or SUPERELASTOCOAT substrate and smoothing it out with its self-leveling ability. Same thing stands for the first layer of ELASTOCOAT or SUPERELASTOCOAT on the substrtate or on the ELASTOSPORT 853 additional layers (if needed) -the consumption will be more than the following layers because of filling in of small irregularities

For around 400 m² you will need three people for 3 days for both systems (ELASTOCOAT or SUPER ELASTOCOAT), average 9 working days in all, in the case ELASTOSPORT is not needed. If there will be a need (most probably) for intermediate ELASTOSPORT layers before ELASTOCOAT or SUPERELASTOCOAT we go to 4-4.5 days for three people, average 12-13 working days in all (and also consider a couple of dead days at least  for the ELASTOSPORT last layer to dry before applying ELASTOCOAT or SUPERELASTOCOAT). So, even with the additional ELASTOSPORT layers, the total application is easier by squeegee than by trowel and cost-efficient because labor cost gets (considerably) down. The dead time between the two ELASTOCOAT or SUPERELASTOCOAT layers (or between the last ELASTOCOAT or SUPERELASTOCOAT layer and ELASTOTURF, or between the last layer of ELASTOSPORT and the first of ELASTOCOAT or SUPERELASTOCOAT) is not considered to be working time. Again, this dead time of course can be utilized for other works, besides the projects are usually considerably bigger than 400m², so the dead time is minimized if different phases of the application take place in different parts of the project. Moreover, for bigger surfaces more square meters are possible per day in average because you will be able to work on bigger open surface with the same materials-and thus minimize dead times.

3. On dry asphalt (or dry waterproof non-polished concrete, preferably after light grinding to provide grip and “bite”) surfaces ELASTOCOAT 841 and SUPERELASTOCOAT 842 applied by trowel (not too common)

Note that we prefer to finish off all exterior acrylic systems with 300gr/ m2 of CONCENTRATED ELASTOTURF 852 (which is mixed 50%-50% with quartz sand 0.1-0.4mm to create ELASTOTURF 851) for better aesthetic result but you could also do it with plain ELASTOTURF 851
