Placing wall coverings step by step

Surface preparation

Each placing of EPIKA DESIGN wall covering should start from surface preparation, which should be vacuumed and free of any residual parts of other paints. First, prime the surface using primers available at the market.

Preparation of adhesive

After priming the surface, prepare the adhesive agent. Using adhesive intended for gypsum tiles, mix it in the bucket according to the instructions found on the packaging.

Cleaning the tiles

Next, prepare the tiles to place them on the wall. Each tile should be cleaned of any unevenness, which may be present on the back side of the tile. Remove any sharp edges as well. Use sand paper, 80 grit, or abrasive net, and a spatula to remove all sharp edges of the tile.

Placing the tiles

Place the adhesive on the tile, and fix it to previously prepared surface of the wall. Start placing at the corner, if there are any, or from the place where the tiles start. When placing the tiles, remember to place them in turns – which means place each layer overlapping. Adhesive should be spread equally on the whole surface of the tile.

Cutting the tiles.

When placing the tiles, it is necessary to cut them, which should be performed with the use of a handsaw or angle grinder with a diamond disc. Additionally, measuring tape and angle plate should be used.

Level control

When placing the tiles on the wall, control the level of the tiles and adjust if necessary.

Tile priming. Finished!

After thorough drying (about 7 days), secure the wall with the preservative EPIKA, which will make it easier to keep clean.

Frequently asked questions:

  • What overage should be assumed when measuring the surface?

    Before you start the work, carefully measure the surface on which the tiles will be placed , and assess how much tiles you need. It is recommended to buy 10% more tiles then results from the calculations (due to cutting). If you wish to cover the edges with edge tiles, you should have 5% more tiles compared to the calculations.

  • Can tiles be painted with wall paint?

    There are several colours of tiles available: white, graphite, and grey. If you wish to change the colour of the tile, cover it with wall paint. However, it is recommended to use white tile if you wish to paint it.

  • Can gypsum tiles be used in rooms where humidity is high (e.g. bathroom)?

    It is not recommended to use gypsum tiles in high humidity rooms. However, if the investor wishes to place them, they should be primed with the uni-ground twice after placing. Places directly exposed to water should also be avoided.

  • Can the fireplace be covered with Epika DESIGN tiles?

    In the case of the fireplace covering, workmanship discipline when constructing the fireplace is very important. Properly constructed fireplace should not heat up to temperature of 75°C. If this condition is met, Epika DESIGN gypsum tiles can be used without worrying about colour loss or resistance.

  • Why colour of tiles is different?

    Even though the formulation is observed and raw materials are inspected, there may be differences in colours. Deviations from colour and texture cannot be avoided.

    The differences in colours may result from maturing conditions (temperature, humidity), as well as various colours of raw materials used in manufacturing process – dye, gypsum. They reflect natural stone even better. Differences in colours are not manufacturing defect, and are not basis for complaint.

    Polish standards regarding gypsum products permit differences in colour on the surface of the gypsum tile.
    In order for the colours to be similar, it is advised to place the tiles random from different packages. It prevents possible contrast differences between individual parts of covered surface.

Plaster decorative stone and concrete decorative stone are tiles produced of synthetic plaster or concrete, respectively. The installation and mechanical processing are easy and effortless.

SUBSTRATE: Concrete, bricks, plaster boards, etc. All substrates should be prepared prior to adhesive application, i.e..: have appropriate bearing capacity and homogeneous structure, be even, clean, dry and free of any dust, oil, grease, adhesive agents, etc. Any surface with unstable, insufficient adhesion must be removed.

INSTALLATION: Use EPIKA GRUNT priming agent before laying the tiles. Start laying the tiles from the bottom, thus supporting the first row of tiles on the floor. Use dedicated EPIKA adhesive agent. If there is no levelled horizontal support for the tiles, before you start laying tiles set the horizontal level at one tile distance from the floor by means of a darby float and level. Apply EPIKA adhesive agent on the tile or along the tile’s edge by means of a notched trowel and push evenly until the excess of adhesive is squeezed out and you feel slight resistance. After the adhesive sets out remove the darby float and fill in the missing row of tiles. Use corner elements to finish the external corners.
Depending on the type of stone, you can lay it with or without grouting. Grouting can only be done after the adhesive has dried completely, with a grout spreader or a home-made grout bag. When the grout has slightly set, you can use a flat tool to smooth the surface. Allow the grouting to dry completely and then use a scrubbing brush to remove the remainings of the grout from the tiles’ edges.

1) Use at least four packages of tiles for laying to obtain a harmonious appearance of shades.
2) Use dedicated products by EPIKA to lay your tiles – the customer bears the responsibility for using other adhesives or grouting .
3) The difference in colour is intentional in order to obtain a natural appearance of the tiles.
4) The ambient temperature during tiles laying and drying must fall between +5C and +25C.
5) Tiles must be cut with metal cutting saw (plaster stone) or with an angle grinder (cement stone).
6) Don’t use an adhesive that may cause discoloration.
7 ) It is recommended to impregnate the surface with EPIKA products after the installation works are finished. Allow at least 7 days after laying the tiles for complete drying before applying the impregnation agent. The impregnant makes cleaning of the stone easier and prevents colour discharges.

EPIKA is not responsible for incorrect laying of tiles on a wall. The differences in shades or shapes shall not give rise to any complaint after installation. All installation works must be performed in accordance with „Technical Guidelines for Performance and Acceptance of Construction and Installation Works“.
