Installation instructionsΑ) INSTALLING CONCRETE PAVERS
The main advantage of concrete pavers in comparison with other flooring materials is that they are simply laid on a bed of crushed sand. This results in easy, accelerated and, above all, cost-effective installation. Moreover, in case that later on we wish to perform additional works on the substrate (e.g. cable passing), it is a breeze to “lift” the pavers, conduct any required works and put them back in place!
An essential prerequisite for a proper paver installation is the ground to be hard and settled and definitely not polder. In case of such a non-compacted substrate, one should definitely proceed to soil “modulation” using coarse crushed aggregates (30-70mm), compaction with a road roller and manufacturing of a substrate using mixed crushed aggregates. Some typical decks for installing pavers are: concrete, earth, asphalt.
Below you may find a simplified description regarding pavers' installation guidelines. However, in case you wish high aesthetics results and quality of construction we recommend that you seek for a professional paver contactor or consult us.
STEP 1: SUBSTRATE PREPARATION
Place the aggregate macadam on the surface on which the pavers are going to be laid. Note that, after installation, the surface shall have been elevated about 10 cm (in the case of pavers or 6cm thickness). Wet the macadam and compact it with a road roller. Remember to take into account that the pitch of the surface should be appropriate so that satisfactory drainage of the rainwater is accomplished.
STEP 2: PLACING THE KERBS
“Casing” is essential in all concrete paver works since it provides for tight interlocking and prevents scattering. Dig a ditch 10 – 15 cm in depth. Compute that the curb clearance (over the compacted aggregate macadam is about 10-12 cm. Plumb the curbs and cement them with mortar.
STEP 3: LAYING THE SAND
Before the paver installation you should lay the sand (of crushed stone) bedding. Level the sand using an ell and create convenient pitches for the rainwater drainage.
STEP 4: INSTALLING THE PAVERS
STEP 5: CUTTING THE PAVERS
Using a ruler, measure and plot every paver you wish to cut. The cut may be conducted with a water cutter, an angular wheel or, even better, a paver shearer. Place the cut pavers, wedging them inside the remaining voids of the edges of the surface.
STEP 6: COMPACTION
Spread over the installed pavers, dry sea sand. Brush with a broom so that the sand penetrates into the joints. Vibrate with a vibrator. Your new concrete paver floor is now ready!
Β) MATONELA® TILES INSTALLATION INSTRUCTIONS
The most common installation methods for Matonela® tiles are
- With tile adhesive and
- With mortar
We recommend that during the installation procedure, particular care and attention is paid so that the laid floor is kept clean..
Installation with tile adhesive
A tile adhesive suitable for natural stone, marble or granite is highly preferable.
- The floor on which the tiles are to be laid should be flat, stable and free of foreign substances (dust, grease, wax, etc). The concrete surface should be constructed a couple of days before the installation in order that sufficient time is given to the concrete to set, mature and dry.
- Prepare the adhesive according to the manufacturer’s instructions. A tile adhesive of category C2TES1 is recommended.
- Apply a layer of adhesive on the floor so as to achieve a good penetration. Spread the adhesive using a notched trowel (at least 10 mm notch size).
- Soak Matonela tiles and lay them right away on the adhesive.
- When installing the tiles in exteriors, it is recommended (as in all kinds of tiles) that expansion joints are kept every 10 sq.m. (m2) which should also include the concrete substrate. These joints should be filled with elastomer as it happens in all kinds of flooring.
Prepare a concrete mix using the following.
- 1 part of grey cement.
- 2-3 parts of aggregate sand.
- 1 part lime (or lime substitute).
- Water until the mix becomes liquid enough to be laid with a trowel.
- Lay the mixture on the floor, in small segments in order to place one tile at a time. The mortar bed should be approx. 2-3 cm thick.
- Place one tile at a time flipping it and press it by hand executing small rotational moves so as to bring one tile adjacent to the other.
- Before laying the tiles you should wet slightly the concrete floor.
- When installing Matonela tiles for interiors (Polished or Antique) there is the option of no joint setting. For exteriors we recommend a joint of 6mm or greater.
For achieving a perfect outcome we suggest that you clean and seal the installed tile floor. These works should be conducted immediately after the adhesion of the tiles and before grouting.
All joints should be properly cleaned before grouting. The excess grout should be removed immediately.
- It is advisable to use grout that matched the tile color so as to avoid color variation on the tile surface.
- Especially in the case of installing Matonela tiles of light colours (white, yellow, ochre, etc) caution should be taken that the grout is light-colored as well since, there is a probability, that darker colours stain the tiles (and make after-cleaning a quite difficult task).
- For removing excess grout from Natural and Shot blasted Matonela tiles use a stiff brush or a sponge. Go over the surface as many times as necessary to clean completely the excess grout.
For Natural and Shot blasted Matonela tiles we suggest the following:
- Joints equal or greater than 6mm
- Good cleaning (of tile adhesive residues, stains, dust or other impurities) otherwise the sealing process will entrap all these undesirable substances making further cleaning very difficult.
- Sealing using our impregnating sealer “Seal 10”
- Grouting with coarse grout (used for joints exceeding 6mm) after 24 hours. Remove excess grout immediately using a sponge and water.
For Antique and Polished Matonela tiles we suggest the following:
- Good cleaning (of tile adhesive residues, stains, dust or other impurities)
- Sealing using our impregnating sealer “Seal 5”.
- Grouting 24 hours after the application of Seal 5
Alternatively (for Polished and Antique tiles):
- Good cleaning (of tile adhesive residues, stains, dust or other impurities).
- Soak the tiles and grout using the same color as the tiles (or white). Next, clean using a sponge, well.
