Instructions for applying and maintaining the decorative elements:
Decorative elements are manufactured in order to resist temperature variations. Even so, during the cold season they must be water emptied from the inside out, dried and foiled, in order to protect them from the harmful effects of the frost-defrost process.

Useful information before applying/mounting:
Natural stone plates are often tightly packed in crates and might be dirty from the different finishing processes which occurred prior to packaging. It is therefore recommended to wash and dry the natural stone plates prior to installing, using either water or a professional cleaner. The plates must be dried so that those which present themselves with minor faults are placed in less visible areas or are used for cutting up. Please make sure that the natural stone plates are mixed up before mounting. This means that you must open up all crates and all pallets from the delivery. All plates must be unpacked and those responsible for applying them must be aware of your requirements.
Minor damages such as cracks often come up while packing or unpacking of the plates and it is perfectly normal. Use those plates for cut-ups or in less visible areas. Apply the plates starting in the middle of the room. Make sure to dry them before mounting in order to prevent improper cuts or so that you can adjust the layer of putty for uneven plates. These kind of plates should be picked out and marked. The thinner pieces will determine the height of the floor so they should be applied in the beginning. In this way they can be heightened with an adhesive fit for the floor in large format.
The presented dimensions are nominal meaning that small variations in size and thickness may occur in the case of flooring tiles. The support surface should be uniform, evened out, dry and free of dust, grease or dirt. Make sure to talk to those who are going to apply the floor so that they are familiar with the products which they are going to apply in order to meet your expectations.
All natural stones, terracotta, ceramic and porcelain tiles must be extremely well fixed once applied. Use a flexible adhesive such as weber.set stone or weber.set marmoplus for areas with high levels of humidity or for heated floors. The color of the adhesive which you are going to use depends on the color of the stone and the grout. For example, if you want to apply pale limestone you must use a white adhesive in order to prevent any shadow or sign of dirt.
Mix the adhesive following the instructions, add the powder in clean water and stir until you get a smooth consistency. Make sure to mix enough adhesive for your product. The support surface must be cleaned, always even, dry and stable. Make sure to also clean the faces of the ceramic plates so that they are free of grease, oils, dust or other impurities. The adhesive mortar must be laid on the supporting surface using a grooved trowel. In the case of big dimensioned plates, the adhesive will be applied on both the supporting surface and the back of the tile. The plates are then manually pressed until an even surface is obtained.
The plates must be placed on the adhesive layer in the designated time. Work on small areas and remove all traces of dry adhesive. The back of some plates which are totally uneven such as some types of travertine must also be heightened using adhesive. Make sure that the substance is perfectly laid on the plate so that no empty spaces are left on the plate's surface. You may clean the extra adhesive before it dries out using a wet sponge. It will be a lot harder to clean once dried. Do not step on the freshly mounted tiles before the adhesive fixes. This may take 3 hours for quick fix adhesives and up to 4 hours for the standard ones.
In order to even out the differences which occur when applying uncalibrated pieces of natural stone on a large area you should use flexible adhesive. These will only be noticed if you apply a mix of different sizes from an uncalibrated material.
When joining natural stone it is recommended to use cement-based grouting. The stones which have a textured surface may need 6-10 mm grouts whereas finished and matted stones could use 3-5 mm grouts. All grouts should be cleaned free of dust and dried out adhesive. Before grouting it is also recommended to wait 24 hours since cladding the floors or walls.
Mortar is applied in the opened joint network using a rubber float or a squeegee for joints until the grouts are completely filled. Excess material is then removed with moistened sponge float. The grouts must have at least 3 mm of space for allowing any movement of the tiles. It is not recommended and it is not possible for the tiles to be completely attached. The grout's width must allow any plate whose dimension varies to be attached to the floor. When applying a mix of different sizes such as a French pattern flooring, the empty space between grouts will vary in terms of thickness because of the plates' configuration model.
Use LTP wall and floor grout protector in order to protect the newly applied pieces from the residual mortar and the grout used for cladding. It plays a great part in protecting the grout from water, dirt, oils, greases and limescale. Any trace of dirt or putty found on the surface of the tiles should be removed while grouting. It is recommended to wash them immediately after grouting using a proper cleaning solution, but before waterproofing.
In case you need flexible adhesive you should only use one side of flexible grouting. All natural stone pieces must be waterproofed using a thin layer of water repellant right after grouting because some plates might absorb pigments out of the cement-based grout. The powerfully pigmented grouts can be subjected to efflorescence as the salts contained in the pigments will be releases once the stone dries.
Rock Star Construct offers to apply natural stone, decorative stone, marble and granite. The price of installing will be determined on site. The appliance is taken care of by our specialists, ensuring a professional installation for any of the following: granite, marble, travertine, natural stone, paving, pavement.
How to build a stone walkway over sand bed
Building a stone walkway in your courtyard does not require a lot of experience and you don’t even have to cut or arrange the stone in a special way. All you need is a large quantity of sand for underlay and just lay the stone over a sand bed, then tamp it with a rubber mallet (hammer).
You have to carry stone and soil (more or less, depending on your walkway) so you will need shovel and wheelbarrow. If you have a longer walkway, use a lawn mower, but you can also strip the grass with spade and pickaxe. You will also need a rubber mallet for fixing the stone in the sand and hand tamper or jumping jack tamper for soil compaction. Other essential tools include: broom, spirit level and a pair of work gloves.
Calculating the area | Expert advice
Calculate the total walkway surface and add 15% more for making sure you never run out of materials, while also covering possible losses (cracks or tiles that you do not like). If you want stairs for your walkways, better ask professional advice from your stone provider, or from a qualified person in natural stone installation. This will clarify exactly the required quantity of stone for this project. Although many natural stones for walkways have a price per sqm, there is also natural stone (cobblestone) sold by weight (1 tone).
Steps for installation
1. Mark the pattern on the grass, using spray or colored dust.
2. Dig for at least 20 cm in depth. Ideally, soil should be levelled afterwards with hand tamper or jumping jack tamper.
3. Pour a layer of sand of approximately 7 - 8 cm. Sand thickness have to be estimated because you don’t want to exceed grass level. Perhaps test it on an inconspicuous area: pour the sand, lay a stone then fix it with rubber mallet and use tools for soil compaction.
Depending on the stone level, you may need extra sand (or not). Because you want to level the stones, use a levelling rope attached by 2 sticks on both sides of the alley. Using the rubber mallet or a soil compaction tool, strike the tiles until reaching the same level.
Very important: keep in mind the drainage gradient of walkway, for keeping the water out.
4. Sand is poured from edges to center, at the same time with laying stones over sand.
5. Stones layout needs at least 5 cm between them, for obtaining that natural look. Also because of this, tiles layout will combine many colors and shapes, for avoiding areas with similar shapes and colors. There is no problem if you have 10 cm distance between stones, because these will be filled with grass, moss or other plants, rendering a very “virgin” look, looking as if it was shaped by nature.
For a general view over your project, step back, examine and move or replace the stones that you do not like.
6. Using the wheelbarrow, mix sand with potting soil in equal ratios and pour the mixture over the tiles joints, spreading it with a broom.
7. Use the spaces between stone for sowing plants. The deeper the roots, the more steady over time will be your walkway.
You can choose your natural stone for this project from the category “Polygonal Flagstone” available on PIATRAONLINE extended range of products.
How to obtain French Pattern layout?
French Pattern Layout (also known as Versailles) exhibits a very dynamic and relaxing structure in every decoration project that use it. It can be used for flooring in public or residential areas, such as bathrooms, kitchens, living rooms, restaurants, hotels, swimming pools, saunas, lobbies etc. Usually, this pattern fits perfect in projects with rustic or Mediterranean design. There are many French Pattern models, with structures established by the number of pieces and size. Many French Pattern models are available as sets, but there are also models sold by piece.
Regarding the finish, we have: brushed with chiseled edges, tumbled, bush hammered, brushed and chamfered, polished etc. French Pattern models are mainly associated with travertine, but there are also with marble and slate.
The list includes: trowel for applying mortar, bucket for mixing adhesive (and also for grout, if you want joints), carpenter pencil (or a tool for scratching the tiles to be cut), angle grinder with diamond blade, spirit level, sponge or damp cloth for wiping excess adhesive (or grout if you want joints), mortar and adhesive power mixer, working gloves, safety glasses.
Calculating the area
We recommend you to buy with 15% more than quantity needed for flooring, for covering your losses with transportation and installation. Depending on model, each set will have a specific surface, so before buying make sure you have sufficient tiles/sets for covering your needs.
1. Before starting, make sure you have a working surface that is steady, even, dried and perfectly clean, free from impurities. Observing these conditions will guarantee a better contact between adhesive and underlay. An imperfect contact may lead to tile detachment and even cracking.
2. Tiles have to be prepared (washed and dried) for installation. A tile free from impurities will have a better contact with adhesive.
3. Pour adhesive in a bucket and mix it with a power mixer, according to directions printed on packaging box. We recommend using a flexible adhesive.
4. Apply adhesive evenly, on both underlay and tiles surface; use a trowel.
5. French Pattern tile installation starts from the middle.
6. For cutting tiles extremities, use an angle grinder with diamond blade.
7. Each specific model should have a sketch, available online or at your stone supplier. This sketch features a digit or letter stamped on each piece of the set.
8. Use back of your hand for softly pressing the tile over the adhesive.
9. Use a spirit level, for making sure you have an even surface.
10. The adhesive protruding from under the tile when pressing softly is wiped out with a sponge.
11. For avoiding color levelling, we recommend using tiles from different packs during installation. Color levelling means that some spots from your flooring will look like stains over large areas, due to similar shades exhibited by tiles from the same package.
12. The ideal procedure for installation includes laying out the tiles over a flat surface prior to installation, for giving you an idea of how flooring will look like.
13. Prior to sealing, wash the tiles and allow them to dry.
14. For installation with joints you have to use standard spacers (common for installation of natural stone or ceramic tiles), available in any DIY stores.
15. Grout is mixed in a clean pot, using directions printed on label.
16. Grouting is done with putty knife. Using a sponge or damp cloth to remove excess grout immediately, before it hardens. While removing excess grout, make sure tile is consistent and even, for creating a well-balanced and pleasant appearance.
17. In the end, apply a professional sealing solution for natural stone, for better protection of surface against liquid absorption.
Wall Cladding with polygonal flagstone (interior & exterior)
Polygonal flagstone is usually associated with rustic and Mediterranean design styles. Both are very popular in Romania and you can see it in residential or public decoration projects (hotels, wine cellars, restaurants, tourist villas etc.)
- if your location is not close to warehouse, use wheelbarrow for carrying tiles,
- trowel for applying mortar,
- hammer for cracking stones to obtain the needed profile,
- carpenter pencil or tool for scratching tiles and marking the profile,
- bucket for mixing mortar and later for adhesive,
- rubber mallet,
- angle grinder with diamond blade,
- mortar and adhesive power mixer,
- working gloves,
- safety glasses.
Add an extra 15% to the total surface that needs to be cladded, for making sure you have enough for your decoration project and also covering the possible losses (cracks or tiles that you don’t like etc.). Usually, you can buy natural stone by sqm and sales experts will tell you exactly how many tiles from each product are included in a square meter.
1. Because polygonal flagstone have considerable weight, we recommend welded wire mesh for reinforcement.
2. Mesh is attached to the wall with plaster.
3. Wash and dry the tiles, before installation.
4. Wait for the plaster to be fully dry, then apply adhesive on both underlay and tile. Tamp down the tile with the back of your hand or a rubber mallet.
5. You can install tiles as they are or you can use a hammer for chipping edges, for a wilder look.
6. If you want a specific shape, cut tiles with diamond blade.
7. Polygonal flagstone can be installed with larger distances (joints) between tiles or smaller distances. The latter solution requires a lot of effort, skill and time for fitting the tile shape with contour of an adjacent tile. For larger joints, tile chains can form shapes similar with the adjacent ones.
8. Joints can be covered with grout for natural stone. Use matching color grout or different for marking your pattern resulted from joining tiles. Complete grouting stage, then wipe the excess grout immediately after application, with a sponge or damp cloth.
9. Joints can be left un-grouted; just fill spaces with adhesive up to a certain level. For aesthetic purpose, level should be the same all over.
You can choose polygonal flagstone with different shapes and colors for wall cladding, available in the category “Polygonal Flagstone” from PIATRAONLINE range of products.
How to Install Terrazzo Tiles?
Terrazzo is a hand-crafted, special, decorative tile used for wall cladding and flooring. The precious figures should not be expected on the surface of a terrazzo tile as much as an industrial printed tiles have. And the small design flaws should be considered a unique character of that tile itself like a handmade carpet. With proper care, your terrazzo tiles will last for years without losing their beauty.
Instruction to Fix Terrazzo Tiles:
1. It is suggested to fix the tiles after all other applications are completed. If any application (painting, repairing etc.) is necessary after terrazzo tiles are put in place, we recommend covering the floor, to protect it from dirt.
2. If the surface is not plain enough, use Weber.Set Stone for levelling the differences. Otherwise the joints between tiles may look imperfect due to different levels of tile edges. It may also cause difficulty to use.
3. Before starting, each box should be checked for tonality. The tonality code is printed on each box. The tiles having the same tonality code should be used on a particular area.
4. It is recommended to use white tile adhesives for fixing. The dark colored adhesives may cause dirt. The back side of the tile must be clean. The adhesive is spread on both to the floor and the back side of the terrazzo tile. The tile is placed on its position and pressed gently. A soft rubber hammer is recommended to use for fixing. A metal hammer should not be used; it may crack or break the tile.
5. The wide joints between the tiles are not recommended. The distance between terrazzo tiles should not exceed 2 mm.
6. One day after fixing, grout the joints with Weber.Color Comfort in your desired color. Prepare your grout by adding it in water and mixing until it becomes a paste. The grout is applied between joints by a putty knife. The excess grout should be cleaned immediately with sponge and water.
7. The surface over which terrazzo tiles are installed should be used according to “Instructions to Use and Clean”.
Instructions to Use and Clean:
1. The resin to protect the surface against stains is applied on the tile surface at the factory. But due to certain water absorption of the tile, it may not provide complete protection against stains. Therefore stains from coffee, tea, meals or painting residues should be removed immediately.
2. You can use soap, brush and sponge for cleaning. Any acidic cleaners (such as hydrochloric acid) must not be used because they damage surface and tile colors. For aggressive stains, use LTP Power Stripper - Professional natural stone intensive cleaner. (You are recommended to use gloves for your personal safety).
