FIELD: construction.
SUBSTANCE: tape is designed to fill seams between construction slabs. It contains a non-woven base, containing fibres, selected from a group made of natural cellulose fibres, synthetic polymer fibres, glass fibres and their combinations. At the same time the nonwoven base has the following properties, determined according to ASTM C474-05: relative swelling in cross direction is below approximately 1.3%; relative swelling in longitudinal direction is below approximately 0.2% and breaking strength in cross direction is at least approximately 2625 N/m. Besides, a method is proposed for finishing treatment of a seam between slabs, including the following: (1) application of a tape for filling seams onto a seam between slabs by submersion of a tape for seam filling into the first layer of the composition for filling seams; (ii) application of the second layer of the composition for filling seams above the tape, besides, the stage (ii) is carried out before the tape for seam filling and the composition for seam filling applied at the stage (i), have dried substantially, and if required, (iii) application of the third, filling or final layer of the composition for filling seams above the tape, besides, the stage (iii) is carried out before the tape for seam filling and the second layer have substantially dried.
EFFECT: improved quality of the tape due to high strength and reduction of swelling during moistening at simultaneous acceleration of seams filling.
