Laying Techniques Laying techniques are crucial to the general appearance of the carpet and the comfort they afford; they also affect the product’s durability and acoustic and thermal properties. Apart from free-form laying, which any skilled handyman can do, we always advise using a professional. Fitted carpet should be laid on a fl at, sound and clean floor in accordance with the requirements of DTU 53-1 standard NF P 62-202 (see page 103). Wool carpets should never be laid in rooms with underfloor heating. The choice of method depends on the type of carpet, the area to be carpeted, the condition of the floor and the financial implications of each of these techniques. It also depends on the backing. Latex foam backing:Replaces the underlay used for stretched carpets. Action back (jute or synthetic) or felt backing (Confortback):These carpets can be glued or stretched for areas under 20 sq. m, or laid free form according to their intended use. Non-slip carpetsTo prevent rugs slipping on smooth floors or bucking on carpet, "non-slip" or "nonskid" products should be used, which prevent premature wear. Free-form layingFor lightweight usage in small rooms, carpet may be laid free form, just cut to shape (free-form laying is only suitable for rooms under 16 sq. m). Use double-faced adhesive tape to maintain the carpet around the side of the room and diagonally. GluingThis method is generally recommended for all types of surfaces and is essential if the P3 class is required. This should be done by a specialist. Only action backed, felt-backed or foambacked carpets can be glued. A suitable glue (see glue manufacturer catalogue) is applied to the entire surface to carpet, which should be fl at, dry and clean or so rendered by suitable preparation (see DTU 53-1). Great care should be taken in gluing carpet. All wrinkles should be removed over the entire surface. Nowadays there is a new generation of glue called "fixer", which is applied with a roller and is particularly easy to remove; only one layer of glue, removable with water, covers the floor. StretchingWeave carpet should preferably be laid using the stretching technique, which can only be done by a specialist. Generally, laying the carpet on an underlay (an elastic underlayer) can prolong the life of a weave carpet by at least 30%. It also is more comfortable to walk on and quieter. This technique consists in stretching the carpet by anchoring it to tackless strips fixed to the floor around the edge of the room. The floor should be fl at, dry and clean or rendered so with an appropriate technique before laying the underlay. Stretching enhances all the qualities of carpet: comfort, resilience, elasticity, soundproofing and thermal insulation. Laying on a textile strip:This new technique can only be used on carpets made with our new underlayer with integrated felt underlay, CONFORTBACK. CONFORTBACK affords:
CONFORTBACK carpet is laid using textile tackless strips a few centimetres wide, which should be installed first on a clean and dry surface, leaving a 1 cm gap between them and the wall all around the room. Press the carpet backing firmly down on one side of the room. Stretch and attach the opposite side. Then stretch the 2 other sides in the same way. | ||
