• Excellent adhesion.
• Stable supports.
• Mortar of semiflexible behavior in comparison to a traditional mortar.
• Application in interiors and exteriors.
• Water-proof.
• Permeable to water vapor.
• Resistant
• Easy mixing and application.
• MORCEM® DRY SF PLUS is in conformity with the requirements established in the Royal Decree 140/2003, whereby there are established the sanitary criteria of the quality of the water of human consumption.

Durability

Carbonation rate.

Through tests carried out at the Eduardo Torroja Institute of Construction Science in accordance with standard UNE EN 12390-10 - Determination of the resistance to carbonation of concrete at atmospheric levels of carbon dioxide over a period of one year, Morcem Dry SF Plus has been found to have a carbonation rate (K) of 2.08 mm/year^0.5 in the case of samples subjected to freeze-thaw testing with thermal shock and immersion in a saturated solution of de-icing salts, and a carbonation rate (K) of 0 mm/year^0.5 (no carbonation profile) in the case of samples not subjected to freeze-thaw testing with thermal shock and immersion in a saturated solution of de-icing salts.
These values can be incorporated into models for estimating the corrosion service life of reinforced concrete elements and used to calculate the depth of carbonation using the expression: P = K * t^0.5, where ‘P’ is the depth of carbonation expressed in mm, “K” is the rate of carbonation expressed in mm/year0.5 and ‘t’ is the time expressed in years.

Suitable Substrates

• Concretes, prefabricated blocks of smooth concrete and fillings rich in cement. The supports must be resistant, stable, healthy and  clean, exempt from powder, remains of gratty, organic products, etc.
• In case of heat, wind or on very absorbent supports, we should dampen the support and expect to the disappearance of the water dusting.
• Supports that are not subject to large movements.
• Damaged concrete and cracks must be repaired previously with MORCEMREST® RF 15 or MORCEMREST® RF 35.

Application Procedure

• Mix mechanically component A powder with 3/4 parts of component B liquid. Then add the remaining liquid component and then mix until the dough become homogeneous.

Recommendations

• Do not apply below 5 ° C or above 30 ° C.
• Preferably do not apply with risk of frost, rain, strong winds and direct sunlight; or protect it.
• To ensure the impermeablity, the minimum thickness must be 2 mm.
• At critical points of the impermeable element , it is recommended to arm the coating between the two coats with a strip of squared thin mesh, MESH DRYPOOL or GEOTEXTILE PU (100 gr)
• It must place as carefully as possible, avoiding bags or folds in the armed one. The unions of the armed one will be realized for overlap with a minimal width of 5 cm.
• The union between wall-wall, wall-floor, wall-cell recommended the application in the form of half-round 5 x 5 cm MORCEMREST RF 15 or MORCEMREST RF 35.
• Consult the Technical Department for any application not specified in this datasheet.
• For all information regarding to the safety in the handling, transport, storage and use of the product with the version updated of the Safety sheet of the product.
