When describing the UK 400, the terms “allrounder” and “specialist” are no contradictions because the product is both: versatile in use, but at the same highly specialized in its respective application field. Just one bucket of UK 400 – this is enough for nearly all standard installations of textile and resilient flooring. It doesn’t take up much space in the van and, more importantly, eliminates the risk of choosing the wrong adhesive on site. These features have earned the UK 400 a large number of fans over the years.

 

 As a result of the most recent facelift and reformulation, the adhesive now features even higher initial tack. On top, the latest UK 400 generation offers a longer and thus optimized working time. This makes the flooring adhesive an ideal choice for major building projects where large floor areas need to be covered.

 

UK 400 can be used for bonding homogeneous PVC flooring (sheets and tiles), PVC design flooring, PVC composite flooring with textile backing, CV flooring as well as tufted carpeting with textile backing, linoleum sheets and tiles, and PVC design flooring in private areas subject to light traffic. Moreover, UK 400 can be combined with Ceresit Floor® damping underlays on absorbent substrates.

 

PVC flooring

When used under resilient PVC flooring, the adhesive is applied with a trowel of notch size A2. Especially on absorbent substrates, only apply as much adhesive as can be covered with flooring within the open time (while the adhesive is still wet).

After a flash-off time of approx. 15 minutes or after doing the finger test, place the flooring into the still wet adhesive. Take care to avoid air pockets and always rub the flooring carefully down to ensure good adhesive transfer to the backing.

After that, the flooring must be free of tension and lie flat on the surface. Otherwise, use weights to flatten the flooring in the respective places. Avoid excessive stress on the seams. Do not expose the freshly bonded flooring to high amounts of moisture, for example by cleaning. Also protect the area from direct sunlight, especially in the curing phase. 24 hours after installation, the seams can be sealed or welded.

 

Textile flooring

Depending on the structure of the backing, the adhesive is applied with a B1 or B2 notched trowel. After a flash-off time of 10 to 15 minutes, the textile flooring can be placed into the still wet adhesive. To ensure quality workmanship, it is vital to avoid air pockets by all means. Therefore take care to rub the flooring down over its full surface. When laying materials under high tension, it is necessary to rub the seams and head ends down again after some time.

Step by step

Substrate Preparation

Substrates must  be clean, free from structural defects, firm, dry and free of substances which may impair adhesion. After mechanical pretreatment (e.g. grinding/vacuuming), prepare the substrate with suitable primers and levelling compounds so that it is ready to receive floor coverings.

See more details for the preparation of the substrate in the Technical Data Sheet.

Application

Stir the adhesive well and apply it evenly on the substrate with a suitable notched trowel.
