Woosoung should confirm, in prior to the PVC vinyl tile flooring, the appropriateness of the products delivered to the site, and report to the supervisor on the flooring condition in accordance with the specifications.

(1) Samples of Woosoung Floor Tiles
(one of the following products that meets the requirements.)
455x455x3 mm, 920x180x3 mm, 920x100x3 mm, 227.5x455x3 mm)
(2) Floor Color Index

A copy of the KS Mark Certificate (KS M 3802), a copy of the Quality Certificate (ISO 9001), test reports, etc.

(1) Tile-flooring test area should be larger than 10 ㎡.
(2) The tile-flooring test areas can be regarded part of the tile-floorings with the supervisor’s approval.

Wousoung reviews all the necessary matters for the PVC vinyl tile flooring and consults with the supervisor.

The materials should be carried to the site as wrapped in packaging and stored undamaged in a clean and well ventilated area.

The materials should be carried and handled with care not to be damaged, and the damaged ones should be taken out in no time.

There should be proper lights at the flooring site.

Completion of tile-flooring should come only after the completion of walls, ceilings, windows and so forth.

Tiles and adhesives should be stored at the site, 24 hours prior to the flooring, in a room temperature (18~22℃). In case of a site that needs floor heating, heating should be off 3 hours before commencing tile-flooring.

Flooring sites should be maintained to be well ventilated.

A written confirmation with examination sealing on should be submitted to the supervisor which requires re-flooring or repairing with free of charge under the contractor’s responsibility in the case that the flooring results in the outcome do not meet the specifications or the requirements stated on the drawings.

Damages to the PVC vinyl tiles that have been finished flooring with should be properly repaired and regularly coated with wax.

Materials, equivalent to or better than Woosoung floor tiles, should be approved by the supervisor with samples as to the colors, property and efficiency, and also with the color index of the manufacturer, test reports and others that the supervisory service requires.

Properties of the materials are subject to KS M 3802(HT type) and ISO 9001 certification.

(1) Clean the existing floor thoroughly → (2) Line up the boxes of tile by lot → (3) Snapping the chalk line in the center → (4) Spread the adhesive → (5) Start laying down the tiles lining them up with the lines → (6) Finish up by mudding and taping the joint of the wall → (7) Press each tile gently → (8) Remove the access and all the haze left over on the tile and clean up the site

(1) Check the followings with the flooring drawings of the site
(2) Before tile proceeding, the floor should be sufficiently and properly dried up to be under 4.5% of water content.
(3) Check the hardness of the floor and if there is any spot that is too soft or dust, make up the surface with mortar and wait until the water content rate goes down less than 4.5% before proceeding.
(4) Clean up the contaminants on the floor such as varnish, paint, lacquer, wax, and the like before commencing tile flooring. Cover up with the contamination preventing tape should there be any surface with no further cleaning up is possible.
(5) Remove the existing floor and the adhesive in order to prevent the products from possible contraction and expansion in case of laying up tiles to wood (plywood) and existing PVC tiles (tiles / light, heavy weight bearing linoleum).
(6) Make sure before proceeding that the floor is flat with no unevenness or curves.
(7) It is important that the concrete and the mortar on the floor is hard enough and that the floor made of artificial marble for watering tools (artificial marble) should be sufficiently dried up with mortar as the adhesiveness could not be strong enough particularly due to its dampness.
(8) Fill up the crack on the floor if any with proper substance to prevent any unevenness before proceeding.
(9) The floor repair substance of Epoxy may migrate the hardener to the product surface. Therefore, it is crucial to finish the area with contamination preventing tapes.
(10) The builder should check all of the above and inform the supervisor or the manager at the site of any problems that he or she may find for resolutions before proceeding.

(1) The materials should be carried in the site prior to tile flooring. Through inspections over the packaging, carry out the damaged ones if any.
(2) In order to screen out the tiles with different colors, if any, from orders, tiles should be arranged by lot prior to tile flooring and the builder should use the tiles from the same lot.
(3) In winter, a room temperature (18~22℃) should be maintained. The tiles and the adhesive should be carried in the site 24 hours prior to flooring for adaptation to the conditions of the site. The area with heating should disconnect the heating 3 hours prior to the commencement of flooring.
(4) Supplementary materials should be ready before the commencement of flooring and should be used after the completion of flooring.

(1) Draw chalk lines according to the construction drawings and the approval of the supervisor should advance to tile flooring.
(2) No other adhesive should be used than the applicable adhesives. User manual should be carefully studied before tile flooring.
(3) Square shape tiles should be constantly lined up.
(4) Placing tiles on the floor to keep going forward is not allowed. Make sure that tiles are tight to the floor at all time with no gaps. Check them frequently and press down for any gap found.
(5) Remove the adhesive left over on tiles at once.
(6) During the winter, the supervisor or the manager at the site should prevent lights from coming directly down to the tiles that may cause expanding and swelling of tiles.

(1) Set up the chalk string in the center of the floor and divide into four equal parts. Proceed on a quarter section in a ‘L’ shape as shown in the picture below.
(2) How to Mark the Center Line
- Length of one side of the room ÷ Length of one side of the tile = An odd number, which makes the central spot the center line.
- Length of one side of the room ÷ Length of one side of the tile = An even number, which makes the spot 1/2 of the length of the tile away from the center the center line.
(3) Spray the adhesive appropriately considering the work speed due to time limit.
(4) Press onto the outer edges of tiles with hands and feet after having the tiles bonded onto the floor. After flooring, finish up with 50Kg roller to press down with no gaps allowed.
(5) When tiling onto walls with floor tiles, care should be taken by tailoring the tiles as small as 1mm away from the wall for insertion, and repeat pressing for a perfect bond.
(6) The builder in charge should review the floor installed with tiles after completion of tile flooring.

Subject to the quality and construction management rules.

(1) Check the directions of the tiles, bonded area and tailored shapes.
(2) Check the possible swells and gaps.
(3) Check the finishes on walls

(1) Keep the room temperature for 48 hours at least to prevent the swelling of the outer edges of tiles that may happen due to possible changes in the nature of the adhesive caused by air conditioning and heating before the adhesive gets hardened enough.
(2) Carefully keep the tiles from any damages that can be done during heavy-carries by being dragged or dipped.
(3) Do not use strong solvent such as acetone or thinner but alcohol to remove contaminants on the surface of tiles.
(4) Take special care against contamination that may occur after flooring on the surface of products as contaminants (acid substances) might drop on.
(5) Neither moving household stuff nor heating rooms is allowed until 48 hours after flooring, except for walking as it takes 48 hours for the oil-based adhesive to get completely hardened.
(6) After flooring, install supplementary components and fix the floor by taping the area that is over-layered in order to prevent them from being shoved.
(7) After flooring, regularly coat the tiles with wax for on-going maintenance and durability increase of Woosoung floor tiles.

(1) Remove water, oil and sand that may cause the floor slippery. Do not use any polish that may cause the floor slippery.
(2) Neither a rough handling nor a high-stacking of the products is allowed. It may cause injuries and property damages as well as products break downs due to the heavy weight.

(1) Do not use strong solvent such as acetone or thinner but alcohol to remove contaminants on the surface of tiles.
(2) Clean up the drops of chemical agents like bleach and dyeing in no time because it may cause spots and speckles to accelerate changing colors as the transparent chemical substances penetrate into the floors.
(3) Burning the left over after construction would cause the noxious fumes. Entrust industrial waste treatment companies to handle such disposal.
(4) Do not wrap off boxes and keep them in a flat area. Staking tiles on layers for a long term or standing tiles up may cause them distorted in shapes. Direct sunlight and being wet may also cause distortion of the quality and colors.
(5) Avoid furniture paint, insecticide and preservatives that may cause tiles contaminated. Take a special care when using them not to stain tiles. (6) Woosoung floor tiles are only for floors.

(1) Place the adhesive case upside down for 20 minutes and then shake before using adhesive for coating.
(2) Spray only the instructed amount of the adhesive over an appropriate area of the floor for one time work. (It is important to use a proper amount of adhesive as instructed for quality bonding to avoid defect that may occur by using too much adhesive for one time work as it gets hardened fast.)
(3) Pay attention and keep the open-time because the open time and the pot life depend on the season and weather.
(4) Neither moving household stuff nor heating rooms is allowed until 48 hours after flooring, except for walking as it takes 48 hours for the oil-based adhesive to get completely hardened.

(1) Warning: The adhesive for tiles installation contains organic solvents harmful to human body and may cause an addiction or a hallucination once inhaled over certain amount. Wearing a protective gear is mandatory. Frequently ventilate the area and inhale fresh air.
(2) Watch point: Right after the construction, there could be strong smell of the adhesive remained. Sufficient ventilation is required.

Woosoung is not responsible for any defect that might be caused by not following the instructions of the tile flooring. Please be fully aware of the content stated in the floor tile specifications herein and also stated in the sample book prior to commencing tile-flooring.
