LASTOFLEX-ST is applied by roller, brush, or air gun even in a single layer up to consumption of 1,6 lt /m². For improved mechanical and crack-bridging properties, it is recommended to apply LASTOFLEX-ST together with ELASTOTET GEOTEXTILE (non-woven and needle-punched polyester geotextile of 120 gr/m2).
The geotextile is applied on top of the freshly laid first coat of LASTOFLEX-ST, before the application of the second and the third layer.
The use of LASTOFLEX-ST together with geotextile is highly recommended for sealing the areas of joints and cracks, as well as the corners between the floor and the wall or any other extrusions such as chimneys, bases of solar panels, upstands etc.
Furthermore, the use of LASTOFLEX-ST in combination with geotextiles is also recommended for waterproofing roofs with cementitious screeds which have the tendency to crack. Time interval between each coat is at least 3 h and not more than 48 h.
When primer is applied, the first coat of LASTOFLEX- ST can be applied not earlier than 1 hour and not later than 48 hours from the application of the primer.
The drying time is significantly affected by the environmental conditions (temperature and humidity).
Only for application by airless spray, it is suggested to dilute the product with the nonflammable SOLVENT D 40 up to 10%. Never dilute the product with water.
The same solvent can be used for cleaning the tools or the equipment from the fresh coating.
Once the material is cured, it can only be removed mechanically. LASTOFLEX-ST is not suitable for application as a directly exposed layer on swimming pools.
LASTOFLEX-ST is 100% UV stable and color stable and it can be applied on top of LASTOFLEX-PU to eliminate the chalking effect and to provide color stability, especially in dark colors such as red, black, brown, or blue.
To make walkways or to reduce slip, the coating can be sprinkled on top with an appropriate particle size of quartz while it is still wet.
Consumption: A minimum consumption of 1,1 - 1,3 Lt/m2 (1,3 – 1,6 kg/m2) is recommended. In any case, the consumption depends on the roughness of the surface or the specifications of the application.
