PRi 400
PRiBOND’S PRi400 is an anti-skid, high adhesion quartz adhesive. It can be applied up to 10 mm bed thickness. High dispersion co-polymers hydraulic binders composed of only cement clinker in PRi400 provides rheological mixture for a prolonged stability. It serves purpose of high resistance laying.
CEMENTITIOUS ADHESIVE FOR ANY KIND OF TILE & STONE
Areas of Application
- Fixing absorbent floor and wall tiles out doors and in doors.
- Fixing on heating floors.
- Fixing poorly absorbent materials or non-absorbent materials such as single-fired tiles, refine porcelain stoneware and vitrified tiles.
- Suitable for use when high performances are required, such as tile fixing in industrial environment or fixing on top of old ceramic tiles or natural stone indoors, in swimming pools or on facades.
- The tiles can be made of cotto, double fired, single fired ceramic.
Features & Benefits
- Floors and walls, for internal use
- Open and adjustability time >30 min.
- Suitable for facades
- Suitable for homogeneous tiles, ceramics, large formats, low thickness slabs and stable natural stone
- Thicknesses up to 10 mm
Preparation of Substrate
- In general, cement-based substrates must be free from dust, oil and grease, dry and free from any rising damp, with no loose, flaky or imperfectly anchored parts such as residual traces of cement, lime and paint, which must be totally removed.
- The substrate must be stable and without cracks, must have already completed curing hygrometric shrinkage and must present suitable mechanical resistance levels. Undulated areas must be corrected with suitable smoothing and finishing products.
Coverage
Approximately 30 to 35 Sq.ft for 20 kgs bag with 5mm x 5mm square notch trowel for a bed of 5 mm
Packing:
20 Kg Bag
IMPORTANT
Adding extra water does not improve the workability of the product, may cause shrinkage in the plastic phase of drying and result in less effective final performance with a reduction in compressive strength and adhesion to the substrate.
Screeds and plasters which present a weak crystalline structure in the initial mm of thickness which can be easily abraded must
be consolidated by means of Primer, the professional, water – base depth consolidant, to be applied with one or more coatings
and according to the instructions, until a surface has been obtained which is still absorbent but compact.
On screeds and plasters which are compact but highly absorbent, in warm climates and with direct ventilation, it is advisable to
apply in advance Primer, a professional, concentrated, water base, surface insulation product, with one or more coatings and
according to the instructions, to reduce water absorption and to improve spreadability of the adhesive.
- Prepare PRi400 in a clean container, first of all pouring in a quantity of water equal to approximate 5 ltr. of that which will be required.
- Gradually add PRi400 to the water in the container, mixing the paste from the bottom upwards with a low – rev (400 RPM / min.) helicoidal agitator. Then add more water until the desired consistency is obtained, the mixture must be homogeneous and without any lumps. For best results and to mix larger quantities of adhesive, a stirring device with vertical blades and slow rotation is recommended.
- Specific polymers with high – dispersion properties ensure that PRi400 is immediately ready for use. The amount of water to be added, indicated on the packaging. It is possible to obtain mixtures with a more or less thixotropic consistency, depending on the type of application.
- PRi400 should be applied with a suitable toothed spreader, to be chosen according to the size and characteristics of the rear surface of the tiles. It is best to use the smooth part of the trowel to spread a fine initial layer, pressing down hard so as to obtain maximum adhesion to the substrate and to regulate water absorption, after which the thickness can be adjusted as required by tilting the spreader at an angle.
- Spread the adhesive over a surface area which will allow for laying of the surface materials within the indicated open time and check for suitability of the adhesive at regular intervals, the open time may vary considerably during the same operation, depending on various factors such as exposure to sunlight, air currents, absorbency of the substrate, temperature and relative
humidity of the atmosphere. - Press down each tile to allow for complete, uniform contact with the adhesive. In the case of laying in environments subject to heavy traffic or in outdoor locations, the double – spread technique must be used, to ensure 100 % coverage of the rear of the tiles.
- In general, ceramic tiles do not require preliminary treatment, however thes
Do not use on substrates with a gypsum and anhydrite base without use of Primer the professional, concentrated, water-base,
surface insulation product
