Dubond's pure is a quartz based tile adhesive, that has excellent results for high resistance laying of ceramic tiles on floor, walls on cement based substrates. It is workable up to 10 mm thickness and the formulation ensures optimum-performance for tile setters. It is absolutely reliable and has its base in superiority of its conception
Green Building Rating
Areas of Application
Designed for ceramic floor and wall tiles for outdoor and indoor . The tiles can be make of cotta, double fire, single fire, ceramic. Floors and walls, for internal and external use, in domestic, industrial and commercial applications also in areas subject to freezing.
Features & Benefits
Preperation of Substrate
Method of Application
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 partssuch 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.
Substrates with weak surface consistency
Screeds and plasters which present a weak crystalline structure in the initial mm of thickness and which can be easily abraded must be consolidated by means of Hydro Prime, 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.
High - absorption substrates :On screeds and plasters which are compact but highly absorbent, in warm climates and with direct ventilation, it is advisable to apply in advance Hydro Prime, a professional, concentrated, waterbase, surface insulation product, with one or more coatings and according to the instructions, to reduce water absorption and to improve spreadability of the adhesive.
Type of application
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.
Pure 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 these materials should properly anchored to the substrate or which may modify the absorption characteristics of the tiles.
Replacement of mixing water with Tuffex AD, the professional elastomer latex, provides the adhesive with greater capacity of transversal deformation and greater resistance to water and tensile stress without modifying the open time and adjustment interval. Pure with addition of tuffex AD exceeds the level of performance required by EN 12004 class C2 E. Please consult the Dubond Products (India) Pvt Ltd site to define use of this product for particular purposes such as: laying on deformable flooring and walls in plasterboard, laying on heat-radiant slabs, laying of large-format paving slabs in outdoor applications and in permanently humid environments, direct bonding on substrates in smoothed concrete with reduced water absorption.
Precautions & Limitations
Do not use on substrates with a gypsum and anhydrite base without use of HydroPrime the professional, concentrated, water-base, surface insulation product1. Heat-radiant slabs.
