Many conditions can cause colored grout to become shaded where some areas match the intended colors yet other areas have varying shades from lighter to darker. This irregularity upon drying of the grout can occur with any cement product and is affected by job site conditions, finishing techniques, and uneven dry conditions. To achieve an approximately uniform colored joint, it is necessary to install grout with a consistent technique for the entire installation. The following steps should be adhered to in order to minimize grout shading:
- Cleaning tile surface and grout joint during installation eases grouting preparation.
- Wait a minimum of 24 hours after tile installation prior to grouting.
- Remove all spacers and keep the width and depth of all joints to receive grout uniform. Remove excess mortar sticking up through grout joint.
- If grouting one area in more than one day plan so that the work both starts and ends in an inconspicuous area.
- Mix grout with the recommended quantity of water and mix to a thick “peanut butter” consistency. Grout mixed too wet can exhibit more shading.
- Let grout slake for 10 minutes prior to use. Add only a small amount of water at this time if necessary to achieve a workable consistency. Do not re-temper the mixture after this point.
- Working time is approximately one hour.
- Keep amounts of mixing water consistent from batch to batch.
- Mix at low speed or by hand. Mixing under high speed can entrain air which can result in weakening the grout mix, create voids and visible pinholes.
- If the face of the tile is very absorptive either dampen the surface with water or use a sealer or grout release agent on the surface of the tile.
- When grouting, fill the joints until flush with the surface leaving no voids. Remove excess grout from the tile with the grout float.
- Allow the grout to become firm in the joint before surface cleaning.
- Remove excess grout from the surface with a slightly dampened cloth or slightly dampened closed cell sponge. Use the least amount of water possible as additional water can cause shade variations and efflorescence.
- To promote curing use Proflex Pro Paper over the installation. Do not use plastic film or printed paper. Do not allow portable heaters to directly effect the surface.
- After 10 days a mild solution of cleanser may be used to remove grout residue. Do not use acid cleaner on the following grout colors: Blue, Mint.
- Do not seal joints for a period of 30 days after installation.
- Though shade variation will subdue over time, the following steps can be used to mitigate minor differences. A mild solution of grout cleaner can be used to remove efflorescence and even variations. The use of a good sealer can improve overall joint appearance and will reduce variation.
- For larger variations, a Grout Colorant may be used to both stain and seal the grout.
- Always test cleaners, sealers and stains in an inconspicuous area first to determine the affect on the installation.
- For maintenance cleaning, use cleansing chemicals designed for certain installations that do not contain strong acid concentration.
