INSTRUCTION ON PVC FLOOR COVERING INSTALLATION, TRANSPORTATION AND STORAGE
PVC floor covering presents a rolled material that consists of several layers.
Upper and middle layers are made of polyvinylchloride, fillers, colouring agents, plasticizers and various additives, as well as glass fiber mat in the middle layer in some collections. The back layer of the PVC covering presents non-woven fabric.
PVC floor covering is designed to be installed in residential and public buildings (groups A, B, V according to the classification established by the Russian Ministry of Health and Medicine). PVC floor covering must not be used in rooms with high traffic with an exception of wear resistant collections ANGARA, SOLID, COMMERCIAL, HARMONY, SPECTRUM, EVEREST, ELBRUS. Constant contact with abrasive materials, oil and grease is prohibited.
Warrantee storage period is twelve months from the production date.
PVC floor covering can be delivered by all means of transport in covered vehicles according to the shipping rules, valid for a particular means of transport.
All the measures providing protection against moisture, damage and pollution must be taken during transportation, loading and discharging.
Rolls must be stored in a dry closed area at a minimum temperature of + 10 °C.
PVC floor covering rolls must be stored at least 1 m. from radiators. Spooled rolls of PVC floor covering must be kept no more than 2 rows horizontally or 1 row up right. In case of storage in specialized cells with shelves representing solid sheets spooled PVC floor covering rolls may be kept up to 4 rows high in a horizontal position.
We recommend selecting PVC floor covering with an allowance of 5-8 cm. in relation to length and width of the room, taking into consideration doorways and walls to avoid or minimize seals between the covering sheets. We also advise to take the vinyl covering from one batch to match the shades of the colour.
Vinyl covering rolls should be unpacked indoors at a minimum temperature of + 15 °C. During the transportation at a temperature from 0 °C to +14 °C, unpack rolls not earlier than in 24 hours after delivery, and at a temperature below 0 °C - not earlier than in 48 hours after transfer to a warm room with a minimum temperature of +15 °C.
After cutting PVC floor covering into sheets we advise to roll them face out on the tube with diameter of 70 mm to avoid fractures during spooling, storage and transportation.
While cutting out the rolls of PVC covering it is forbidden to pull the sheet rubbing the pattern side on the subfloor to avoid damage of the face surface.
The installation of the PVC floor covering should be carried out in accordance with requirements of the set of rules 71.13330.2017.
The subfloor must be dry, smooth, solid, without cracks, dust, grease or oil. We don’t recommend installing the new covering on the oil painted subfloor, on the old covering, on the chipboard or plywood that can distort at changing temperature and air humidity. The subfloor must have a good adhesive absorbing ability, that’s why never install PVC floor covering on painted, lacquered or covered with waterproof agent subfloor.
For leveling the subfloor we advise the following:
- to level the concrete floor with the leveling compound;
- to cover the wooden floor with high quality plywood sheets 8-10 mm thick or fiberboard, nailed at intervals of 150 mm, close up the holes with mastic or putty; we recommend to install plywood sheets checker wise.
- to strengthen and clean the tiled floor, to fill the tile joints with a leveling compound, treating with a suitable primer and to smooth out with a leveling compound no less than 3 mm thick to make the absorbent ground.
- to remove carpeting, clean the surface, treat with a primer and apply a leveling layer
- to remove vinyl coverings and adhesive residues from the base, to treat the subfloor with a primer and to apply the leveling compound.
Underfloor heating system should be switched on for a month. 1-2 days prior to installation heating must be turned off and switched on not earlier than in 72 hours after installation. The minimum temperature in the room when the heating system is switched off must be +15. Next, you need to gradually increase the temperature by 3-5 degrees per day until the desired temperature is reached. The maximum temperature at the junction of the floor covering and the floor base must not exceed 27 degrees.
At the installation of coverings it is necessary to comply with requirements to humidity of the subfloor. Humidity must be no more than 4% for panels of floor separating constructions, no more than 5% for caps based on the cement, polymer-cement and gypsum binder and no more than 12% for caps made of fiberboard.
Cutting into sheets is carried out only indoors at a minimum temperature of +15 °C.
When using several linoleum sheets it is necessary to make allowance for matching the pattern.
The sheets of the covering are installed on the prepared subfloor. Attaching pieces, the abutting edges are overlapped to match the pattern. Only after this you cut the covering along the perimeter with an overlap of 5-10 mm to the wall. In this position, the linoleum is kept for at least two days until any undulation disappears. The minimum temperature in the room must be +15 °C and maximum air humidity - 60%. Don’t install PVC floor covering in places with increased humidity (bathroom, lavatory etc.)
Attention! During installation of PVC floor covering in one room or adjacent rooms take rolls from one batch. At the installation of PVC floor covering in a big space take the rolls successively regarding the roll number. The batch number and the roll number are given in the identification tag.
We recommend gluing PVC floor covering along the entire surface with a specialized dispersion adhesive for PVC coverings. The use of adhesives based on organic solvents is prohibited. Apply adhesive with spatula A1 or A2 equally upon all the surface of the subfloor (consumption of adhesive: 250-400 g/m2). The consumption of adhesive depends on the subfloor surface, the adhesive characteristics and tools you apply it with. Install the covering, match the pattern and fold one half of the sheet. Next, gradually apply adhesive on the subfloor and glue one half of the covering and then, in the same way, the second half. The layer of adhesive must be dried a little, but not to the full. It is done in order to let the adhesive penetrate into the subfloor and depends on the subfloor absorbency, temperature and air humidity in the room, the adhesive applied and its thickness. It usually takes 5-10 minutes (drying time is given in the adhesive manufacturer’s instruction). When installing the covering sheets with the help of adhesive it is necessary to monitor the degree of the substrate soaking. In case of uneven adhesive distribution on the covering substrate, stop the gluing and remove the adhesive residues from the subfloor surface and apply the adhesive again. Glue PVC floor covering to the subfloor over the entire surface except for the sheet joint (about 5 mm) necessary to make the final trimming. Press the sheets of the covering to the floor with a roller from the centre to the sides to remove air bubbles. If you install two sheets of PVC floor covering, roll the compression roller from the sheet joint to the sides and then cut the joint. After gluing cut the covering along the perimeter of the room. To cut the external corners, push the covering into the joint between the wall and the floor, make a little cross-cut along the corner of the wall down to the floor and then pull the covering apart.
To cut the internal corners gradually make diagonal cuts across the material corner till it fits precisely into the corner. To make the final trimming, press the covering with your hand to the wall. Next, cut excess material with a knife, pressing the covering to the wall with a metal ruler or a spatula. After cutting the flooring must not lay close to the wall. To avoid bending of the PVC covering, leave a gap of 5 mm along each wall.
PVC floor covering joints are sealed by a cold welding method with the help of special adhesives. The manufacturer’s instruction on cold welding is given on the adhesive package. Thermo-contact method by means of such devices as “Pilad” and “Master” can also be used. To install Angara, Harmony, Everest and Elbrus hot welding method based on heating the PVC cord with a hot air gun is used. Welding prevents moisture from getting under the covering during the service life. The floor exploitation is allowed minimum in 72 hours after the abovementioned procedures.
Installation of PVC floor covering less than 20 square meters can be carried out without adhesion to the subfloor, fixing it with double-sided tape in places of intense loading. However, the manufacturer is not responsible for this way of installation is doesn’t give any warranties.
Wash PVC floor covering with soap solution or water applied with a soft brush or cloth (maximum temperature is 40 °C). Don’t leave water on the covering. Stains from shoe-polish, rubber traces, iodine, brilliant green and tar must be removed immediately.
Chemical solvents such as acetone, ethyl acetate and other cleaning powders, containing abrasive substances, must not be used for cleaning PVC floor covering.
The contact of the covering with rubber leaves indelible stains on the surface, as well as substances containing bitumen and its derivatives. Rubber-based mats should be avoided.
To protect the covering against damage when moving furniture we recommend using furniture glides made of felt, fabric or PVC. We advise to put doormat in front of the entrance to avoid sand, stones from entering the room, it is advisable to use mats or grids.
