According to the method of stretching floor materials, the tetrahydrofuran-based solvent-type adhesive has a low viscosity and is easy to apply, and only the periphery of the floor material is joined to the waterproof sheet. Therefore, the floor material can be stretched with excellent workability on the upper surface of the soft polyvinyl chloride waterproof sheet stretched on a flat roof or the like, and the working time can be greatly reduced. In addition, since the bonding layer made of the solvent-type adhesive is formed by mutually melting the polyvinyl chloride resins constituting the waterproof sheet and the flooring material, the bonding layer has excellent water resistance and heat resistance, and has excellent long-term adhesion. It can maintain its properties and has excellent durability. The flooring since only the peripheral portion is joined, tarpaulin same
Hardly conspicuous unevenness of flooring even at the stepped portion of the joint portion, and to the appearance is very beautiful, even if the air layer is expanded occurring between even waterproof sheet and the flooring, similar For that reason, the uneven shape of the flooring is hardly noticeable.

Arranging spread by cutting more Do that long flooring long the required length, the peripheral edge portions of the flooring, characterized in that joined to the waterproof sheet through a tetrahydrofuran-based solvent type adhesive, The tetrahydrofuran-based solvent-based adhesive has low viscosity and is easy to apply, and since only the peripheral edge of the flooring material is bonded to the waterproof sheet, the workability is good and the flooring material is very easy to use. It can be stretched, and the working time can be greatly reduced as compared with the conventional case of full-surface bonding using an epoxy resin-based adhesive. Moreover, since the bonding layer made of the solvent-type adhesive is formed by dissolving the polyvinyl chloride resins constituting the waterproof sheet and the flooring material with each other, it has good water resistance and heat resistance,
It can maintain excellent adhesiveness for a long time and has excellent durability.

Further, since only the peripheral portion of the flooring material is joined, the unevenness of the flooring material is hardly conspicuous even at the step portion of the joint portion between the waterproof sheets, the appearance is very clean, and even if the waterproof material is waterproof. Even if the air layer generated between the sheet and the flooring is inflated, the unevenness of the flooring is hardly noticeable for the same reason.

When replacing the floor material, the floor material must be
Because only the periphery of this is bonded to the surface of the tarpaulin, it is relatively easy to peel off, and after removing the old flooring, slightly displace the joint of the new flooring with the tarpaulin. Just as in the initial case, the same excellent adhesive effect can be obtained as in the initial case, so that the work of replacing the new flooring material can be done very easily and quickly, and the finish can be neatly done without unevenness.
