Woodblock RE and WE
Laying
The blocks must be laid in conjunction, with continuous straight longitudinal joints. The direction of laying can be left to the contractor, provided that no special agreements have been made. The work must be carried out using only adhesives and other products for undersurface preparation (e.g. preliminary coatings) which have expressly been declared as suitable for the relevant woodblock and application area by the adhesive manufacturer. TRGS 610 must also be observed. Working joints and safety distances must be adapted to the prevailing circumstances.
Before, during and after the laying time, the room temperature must be maintained at >18 °C and the temperature at the underfloor surface at >15 °C. The relative air humidity should not exceed 65% for any length of time. This room climate must be maintained until completion of the surface.
Sanding
Woodblock RE must be sanded evenly. The number of sanding steps and the fineness of the sanding materials depend on the surface treatment. In the case of woodblock WE, the sanding must be agreed separately. Surface treatment A surface protection agent must be applied to woodblock RE after sanding. Unless otherwise agreed, this must be sealed, e.g. cold- or warm-waxing, hot impregnation, oiling or varnishing. DIN 18367 - VOB Part C - Item 3.3 must be observed.
