Mapei Ultracolour Plus Grout – 5kg

Description

Ultracolor Plus forms a grouting mortar with the following characteristics:

• water-repellent and droplet-effect;
• uniform colour and free of staining since Ultracolor Plus does not produce efflorescence
• colours resistant to ultra-violet rays and atmospheric agents
• short waiting time before cleaning and easy finishing
• ready for light foot traffic and for use after a short period of time
• smooth, compact finished surface, with low water absorbency for easy cleaning
• shrinkage compensated, therefore free from cracks
• optimum resistance to abrasion, compression and flexural strength, even after freeze/thaw cycles
• good resistance to acids with pH > 3

APPLICATION PROCEDURE

Preparing the joints

Grouting may take place when the adhesive is completely set. Make sure that the waiting times indicated in the technical data sheets are followed.
The joints must be clean, free of dust and empty down to at least 2/3 of the thickness of the tiles. Any adhesive or mortar which has seeped into the joints while laying the tiles must be removed while still fresh. With very absorbent tiles, high temperatures or windy conditions, dampen the joints with clean water.

Preparing the mix

While stirring, pour Ultracolor Plus into a clean, rust-free container containing
22-26% by weight of clean water.
Mix the grout with a low-speed mixer to avoid air entrainment, until a smooth paste is obtained.
Let the mix stand for 2-3 minutes, and stir again briefly before use.
Use the mix within 20-25 minutes of its preparation.

Applying the grout

Fill the joints with the Ultracolor Plus mix using a special MAPEI grout float or rubber squeegee, without leaving any gaps or steps. Remove any excess of Ultracolor Plus from the surface, by moving the float diagonally to the joints while the mix is still fresh.

Finishing

When the mix loses its plasticity and becomes opaque, which usually takes place after 15-30 minutes, clean off the excess Ultracolor Plus with a hard, damp sponge (e.g. a MAPEI sponge), working in a diagonal direction to the joints. Rinse the sponge frequently, using two different containers of water: one to remove the excess mix from the sponge, and the other, containing clean water, to rinse
the sponge. This operation may also be carried out with a machine with a sponge belt or rotating disc.
When the mix is partially set, after
50-60 minutes, a damp Scotch-Brite® sponge or an abrasive felt disc may be passed over the joints to even out the surface.
If the cleaning operation is carried out too soon (the mix is still too wet), some of the mix may be removed from the joints.
If grouting is carried out in extremely hot, dry or windy weather, we recommend that dampen the joints filled with Ultracolor Plus are dampened after a few hours.
Damp curing of Ultracolor Plus improves its final characteristics in all cases.
Final cleaning of the powdery film of Ultracolor Plus from the surface may be carried out with a clean, dry cloth.
After the final cleaning operation, if the surface still has traces of Ultracolor Plus due to incorrect application, it may be cleaned down with an acidic cleaner (e.g. Keranet), by following the relevant instructions, at least 24 hours after grouting the joints. Only use Keranet on surfaces which are resistant to acid, and never use it on marble or limestone material.

SET TO LIGHT FOOT TRAFFIC

Floors are ready for light foot traffic after approx. 3 hours.

READY FOR USE

Surfaces grouted with Ultracolor Plus may be put into service after 24 hours. Basins and swimming pools may be filled up 48 hours after grouting.

Cleaning

Tools and containers may be cleaned using plenty of water whilst Ultracolor Plus is still fresh.
