Advantage of Stucco Grout over other cement-based grouts

  • First stucco finish grout of high quality with a high content of calcium carbonates.
  • Best to use for industrial-grade tiles, paver tiles with wider joints.
  • Guaranteed for quick filling of joint up to 12 mm. on the floor & on the wall.
  • Suitable for filling joints in all kinds of ceramic & vitrified tiles & stone including a mosaic.
  • Best of workability, cleaning, and smooth glossy finish.
  • Very high quality of Iron oxide and color stability.
  • High compressive, abrasion & water resistance among polymer class of grout.
  • No water curing requires.
  • Suitable for external & internal.
  • Available in a wide range of 12 colors or more.
  • High coverages with best of performance even in fine joints.
  • Economic & best value using Wallnut Stucco as tile grout.
  • Very low VOC and suitable for green building credit points.
  • it's different from epoxy grout, polymer tile grout ensures color quality. Polymer tile grout is cement-based with added polymers that are activated once they come in contact with water. The chemical reaction increases the grout’s water, abrasion, and chemical resistance and adds an incredible amount of strength.
  • Polymer tile grout is a single component material that is completely stain proof. polymer-based grout is not recommended to be used with pebbles, Should not be used in submerged water or anywhere with high steam.
  • High-traffic residences
  • Commercial spaces
  • Kitchen counters and backsplashes
  • Entryways
Suitable materials for grouting:
  • All types & sizes of ceramic & vitrified tiles.
  • All types & sizes of ceramic & glass mosaic.
  • All types of natural and recomposed stone.
  • Large-format tiles slab of all types.
Surface Preparation:
  • First, check that tiles or stone are fixed properly and are not sounding hollow. In case sounding hollow, the first repair or replace the area.
  • Ensure that joints are clean and free from all foreign material such as oil, grease, dust, etc. In case the dust or cement particles are stuck inside the joint, use a vacuum cleaner or blower to remove the same. The Grout remover tool also can be used in case old grout to be removed.
  • In case working on external façade or on floor joints, avoid applying grout on hot surfaces. First, let cool the surface of tiles or stone and don’t work under direct sun. A hot surface may compromise the final performance grout. In case of high absorbent tiles or stone surfaces, before starting the application, first, apply the grout color in a small test patch area. In case discoloration of the surface occurs, then consult Wallnut technical representative and stop the application.
  • In case tiles or stone are rustic in nature and having uneven surfaces, it is possible that grout residual will remain on the surface while final cleaning. It is better to avoid applying grout on the entire surface area. In this case, edges of tiles or stone can be masked by applying suitable masking tape and can be removed post-cleaning of grouts. 
Mixing:
  • Mix Lite Joint Grout With approx. 2.75 L / 10 Kg. of clean water. Use slow speed electric stirrer for mixing to have desirable results. Manual mixing can compromise the performance of grout and color can be uneven on the final surface.
  • Adjust the water quantity as per ambient temperature and dryness of the surface and joints. The final mix must be a workable paste.
How to apply:
  • Spread the grout evenly on the surface of tiles or stone to cover the area.
  • Once the grout is spread, fill the joint tightly using rubber grout float. Keep the rubber float diagonally to the joint and apply a 45-degree angle to have a perfect filling.
  • Once all the joints are filled properly, remove excess grout if any from the surface of tiles or stone.
  • Leave the grout for surface touch dry. Once the top surface of grout becomes semi-dry, apply all over the surface cleaning sponge using very little water. Use the water only enough to wet the surface area. Apply the sponge in a circular motion all over the joints. Finish the joint smoothly and evenly. (In case excess water is used, it is possible that pigments from the top surface are washed away and the final color of grout may be affected).
