Morcem^® Dry Fix

Technical Caracteristics

Product based on high resistance hydraulic binders, selected aggregates, synthetic resins and special fibres.

Advantages and Uses

• Waterproofing and adhesive mortar in just one single product,it allows the application of the grouting mortar in 8-12 hours (depending on environmental conditions).
• Great capacity to bridge cracks.
• Swimming pool waterproofing.
• Waterproofing of bathrooms, showers, terraces, balconies, etc. and tiles adhesion in just one product. 
• High performance adhesive,fast setting and high deformability (C2FE S2 category) for laying even large format ceramic and thin sheets.
• Excellent adherence to all types of support: ceramic tile, concrete, cement mortar, screeds, stone and brick. 
• MORCEMDRY FIX meets the minimum requirements for the CMO2P category of UNE EN 14891: 2012 "Waterproofing membranes to be used under ceramic tiles"
• MORCEMDRY FIX meets the minimum requirements for the C2FES2 category of UNE EN 12004: 2008 + A1: 2012.

Suitable Substrates

• Direct application on cementitious substrates, concrete and old tiles.
• The substrates must be perfectly cured and resistant, free of dust, dirt, loose materials, release agents, organic products and efflorescence.
• The substrates must have a suitable flatness. 
• A previous treatment by mechanical means, with hydro-pressure washing or sandblasting, may be carried out to remove all old coatings and ensure a healthy and clean surface to provide good adherence of the waterproofing layer.
• When carrying out applications under high weather temperatures, absorbent substrates and porous surfaces will be pre-moistened until saturated , avoiding puddling or condensation.
• Before applying the waterproofing layer, it is recommended to make half rods where the wall meets the slab, using products from the MORCEMREST range. Expansion joints and openings, lights and installations must be sealed with suitable products from the PUMALASTIC range.
• Small honeycombs, cracks or irregularities in concrete can be repaired with suitable products from the MORCEMREST range.

Application Procedure

Mortar mixture:

• Mix the product with the recommended water according to consistency (fluid consistency: 25%; thixotropic consistency: 20%, total mixing time of 3 Min, with an electric mixer at low revolutions (approx. 500 rpm.), until obtaining a homogeneous and lump-free paste. Let the mass rest for 5 minutes and mix again before the application.

Application:

• Preliminary application treating singular points with the BANDTEC band, in the different materials meetings, in construction joints (subjected to limited movements) and other critical areas (such as corners, drains, etc.)
• It is recommended to treat all critical points such as the junction between wall-wall, wall-slab with BANDTEC band.
• BANDTEC is a waterproofing self-adhesive band that can be applied directly on a clean surface, free of dust and below a 4% of humidity , otherwise, apply IMPLAREST EPW primer (see BANDTEC technical data sheet). Once BANTEC is placed, proceed with the application of MORCEMDRY FIX. Structural joints with high movement must be sealed with the ELASTIC MEMBRANE system and MORCEMREST EPOXI T.
• For the application of MORCEMDRY FIX at critical points and other hard-to-reach areas (e.g. corners, half-rounds, drains, etc.) the product can be applied by brush or roller.

Fast waterproofing and tile bonding in 2  simple steps.

• In cracked substrates or substrates subjected to service temperatures below -20ºC, it is recommended to reinforce the waterproofing layer by placing DRY POOL mesh between the two layers of product, avoiding pockets or folds in the reinforcement. The reinforcement joints will be made by overlapping with a minimum width of 5 cm.
• Apply MORCEMDRY FIX with the help of a trowel adding  a suitable compacting pressure on the substrate and creating a homogeneous layer of the product on top of it, with a 2 mm minimum thickness in two layers. Apply a first layer in one direction and let it set for two hours (at 23ºC). Apply a second layer perpendicular to the first one), not giving more than 2 mm thickness in each of the layers (layers must be continuous and with an uniform thickness).
• After 3 hours (23ºC) tiles can be glued on the second layer with MORCEMDRY FIX, for gluing the tiles with MORCEMDRY FIX make sure you are using the corresponding trowel according to the size of the tile.
• The thickness of the product under the tiles must be a maximum of 3 mm (not taking into account the first two layers).
• Spread the kneaded product on the substrate with a trowel to a maximum area of 2m². Place the pieces on the fresh adhesive, pressing and moving until the grooves are completely flattened and the entire surface of the ceramic is correctly adhered. Periodically check the tackiness of the adhesive by lifting a previously laid tile; if a non-transfer film appears on the surface of the adhesive or if the adhesive dehydrates, remove the material and apply a new product.

Waterproofing layer and fast gluing in one coat with a special trowel 

• The application of MORCEMDRY FIX by means of a special trowel (skid trowel) provides us with a monolithic and continuous layer of at least 2 mm.
• Once applied MORCEMDRY FIX, ceramic tiles should be placed immediately after, while still fresh, carefully adjusting and pressing the tiles.
• Total thickness should be between 3 and 4 mm in a homogeneous and continuous layer.
• Remove any possible excess of product from the junctions being careful not to remove the product from underneath.

Fast waterproofing layer, along with special adhesives

• Apply MORCEMDRY FIX with the help of a trowel adding  a suitable compacting pressure on the substrate and creating a homogeneous layer of the product on top of it, with a 2 mm minimum thickness in two layers (Apply a first layer in one direction and let it set for two hours (at 23ºC). Apply a second layer, perpendicular to the first one, not over 2 mm thickness in each of the layers (layers must be continuous and with uniform thickness).
• Three hours after (23ºC) tiles can be placed on top of the second layer with the chosen adhesive.
• The appropriate adhesives will be C2 S1 type (see adhesive technical data sheet), choose the adhesive according to the tile to be laid and the area.
• Respect the construction joints (expansion, contraction, fractionation, perimeter corner joints) and installation joints between tiles (minimum of 2 mm indoors and 5 mm outdoors).
• MORCEMDRY FIX might take longer to cure when laying large format tiles.
• Tools and equipment should be cleaned with water immediately after use being used. Once the product has been completely setted, it can only be removed by mechanical means.

NOTE: The shorter the time between combing and laying the tile, the better results will be obtained.

Recommendations

• Do not apply the product under extreme weather conditions.
• Do not apply under risk of frost, rain, strong winds or direct sun, protect from rain for 12-24 hours after application.
• Hardening may slow down in the presence of high humidity, such as in poorly ventilated rooms or basements.
• If the operating temperature is expected to be -5 ° C or lower, it is recommended to reinforce
• MORCEMDRY FIX with an alkali resistant fibre-glass mesh.
• The product is not passable 
• On ceramic floors (overlays), remove the badly adhered pieces and fill in the gaps with mortar the day before applying the product. Make sure that the old ceramics are free of grease or wax residues, if necessary proceed with the milling of the glazed surface until the old ceramics lose their shine. Check with the Technical Department in case of doubt and carry out the corresponding previous test to stablish the suitability of the given solution.
• On pavements and wall tiles with a surface greater than 50 m² indoors and 30 m² outdoors, or on elongated surfaces of more than 15 linear meters, it is recommended to leave partition or fractionation joints filled with a deformable material from the PUMALASTIC range. It is recommended to leave a free perimeter expansion joint between the flooring and the wall or pillar, hidden by the skirting board, of 8 mm approximately . These joints must be filled with a deformable material from the PUMALASTIC range and combined it with BANDTEC if used outdoors , (see BANDTEC technical data sheet)
• Do not add any cement, sand or any other substances that may affect the features of the material.
• The leak test can be carried out after 4 hours.
• Please check with the Technical Department in case of any other application that may not be shown on the Technical Data sheet.
• For any further information regarding  safety, transportation, storing and use of the product, please check the updated version of the Safety sheet of the product.
