Additional information

Technical Characteristics

Product based on high-strength cement, selected aggregates and special additives, pigments, and synthetic resin.

Advantages and Uses

  • High hardness.
  • Intense colour.
  • Easy to clean.
  • Fine texture.
  • Low water absorption.
  • Resistant to cracking and abrasion.
  • Suitable for interior and exterior use.
  • Compatible with radiant heating floors.

Suitable Substrates

  • Empty joints must be dry and clean throughout their length and depth.
  • Grouting should be done at least 24 hours after bonding on walls and 48 hours after bonding on floors.
  • Before starting the application, PROTECMOR temporary sealer protects porous and non-porous ceramics from potential pigment stains.
  • Do not apply on top of gypsum, plaster, anhydrite, or any other substrates with high content of sulphates, or in contact with water or moisten with high content of sulphates.

Application Procedure

  • Add water (28–35%) and mix manually or mechanically until a consistent paste is obtained (not liquid).
  • Let the paste rest around 5 min. then mix again.
  • Working in small areas, fill the joints with a rubber trowel or rechargeable gun, compacting the material firmly.
  • The application should be done diagonally across the joints, pressing the mixture onto them and removing excess material.
  • Allow the material to dry slightly for approximately 20–30 minutes. When the paste becomes opaque, the surface can be cleaned using a hard sponge, slightly dampened.
  • Only when the product has hardened in the joint, polish the surface with a clean, dry cloth to remove any remaining dust.
  • Let it dry for 24 hours before normal transit.
  • If the ceramics get stained, you can use DESMOR cleaning product as long as it does not damage the ceramics, taking care not to touch the joints (refer to the product instructions).
     

Recommendations

  • The durability of ceramic installation can only be ensured with proper planning. Therefore, we recommend consulting the current national standards in each country, such as the UNE 138002 standard in Spain, which provides specifications for material selection, proper planning, use, and installation, to achieve the required levels of quality, performance, and durability.
  • It is recommended that the grout joints between tiles comply with the requirements set out in Section 7.7 of standard UNE 138002. For interior applications, a joint width of ≥ 1.5–3 mm is recommended, and for exterior applications, a joint width of ≥ 3–5 mm, depending on the type of installation and the longest side of the tile being installed. 
  • Do not apply the product under 5ºC nor above 35ºC temperature.
  • Do not apply under the risk of frost, rain, heavy wind, or direct sun light.
  • Do not use in expansion joints or those subject to structural movements in the construction.
  • In the case of highly absorbent tiles or remarkably elevated temperatures, before filling the joints, dampen them with clean water by passing a wet sponge over them, avoiding water pooling inside.
  • Grouting should be done at least 24 hours after bonding on vertical surfaces and 48 hours after bonding on floors.
  • Joints should be dust-free, free from adhesive residues, and have a uniform depth, at least 2/3 of the total thickness.
  • Do not use on surfaces subject to rising damp.
  • Avoid adding excessive water as it may reduce the final performance of the grout.
  • Do not clean ceramic tiles or mosaic tiles with strong acids or other harsh chemicals, as this may affect the grout colour and reduce its final performance.
  • Fill the joints when the floor or render is completely dry.
  • Do not clean the joint with strong acids or similar substances as it may affect its colour.
  • For renovation work, completely rake out the joints before application.
  • Avoid cleaning with excess water or while the material is still fresh to prevent carbonation and surface tone variations due to pigment dispersion.
  • In areas subject to frost or extreme temperature fluctuations, MORCEMCOLOR EPOXY is recommended.
  • It is important to respect the mixing water quantity, as an excess can promote the appearance of efflorescence on the grout surface and reduce its final performance.
  • Avoid cleaning with excess water or while the material is still fresh to prevent carbonation and surface tone variations due to pigment dispersion.
