Grout Stain FAQ

Q. What are some of the benefits of Spectrum’s Grout Stain?


Q. Can I change the color of my grout?

A. Yes. Spectrum’s Grout Stain allows you to easily change and rejuvenate any existing grout color.

Q. If my grout joint is a dark charcoal color, can I change this color to a light off white color?

A. Yes, because Spectrum’s Grout Stain penetrates it has tremendous hiding power to change dark colors to a light color. If the color change is extremely drastic (black to white), two applications maybe necessary. (Note: the second application may appear painted on, as it cannot penetrate like the first coat.)

Q. If my grout joints were previously sealed with a grout sealer, can I still use Spectrum’s Grout Stain?

A. Yes. Spectrum’s Grout Stain will adhere to any grout joint that has been sealed with a water based grout sealer. However, this may look as if it were painted on. Spectrum recommends the use of a grout sealer stripper before staining; this will open up the pores of the grout and allow the grout stain to penetrate for a “natural” look.

Q. What kind of stripper do I use to take the sealer off my grout joints for Spectrum’s Grout Stain to work correctly?

A. All grout sealers are different, but the base for each is generally a solvent or latex/acrylic. This determines what will break down the sealer to open the pores of the grout. Spectrum recommends contacting the sealer manufacturer for the correct sealer stripper.

Q. If I remove the grout sealer, do I loose my protection from soil or spills that may cause a stain?

A. No. Spectrum’s Grout Stain has the ability to change/rejuvenate colors and seal at the same time. Most grout sealers on the market today promote resistant to staining, giving the homeowner a small window to clean up spills or soils before it actually stains. Spectrum’s Grout Stain penetrates in to create a durable layer of protection that prevents soils and spills from absorbing into your grout joints. By using neutral based cleaners, common household spills can be wiped away leaving the grout looking like the day it was installed.

Q. On what applications can I use Spectrum’s Grout Stain?

A. Spectrum’s Grout Stain can be used in interior or exterior applications on Portland cement or epoxy-based grouts. Some surface areas for example are floors, countertops, bathtubs, showers, fireplaces, bars or any where grout joints are placed. (Note: Epoxy-based grouts are nonporous, Spectrum Grout Stain may look painted on.)

Q. Do I need to worry about staining the tile or walls with Spectrum’s Grout Stain?

A. Caution should always be taken to make sure ceramic or stone tiles are not susceptible to staining. Always do a test in an inconspicuous area to determine any issues. We do recommend that you use a low adhesive tape on all baseboards, walls etc. before applying Spectrum’s Grout Stain.

Q. Can I use Spectrum’s Grout Stain around or in pools and spas?

A. No. The UV rays and the severe environment that chemicals create in the water of pools and spas are generally too harsh for any grout stain.

Q. Can I use Spectrum’s Grout Stain on the grout joints of natural stone installations?

A. Yes. Care should be taken here. Stones and granites can be porous and should be sealed before any grout stain is applied. In addition, the polish on some stones or granites can be affected from the scrubbing in the application. Spectrum recommends that a test area be done in an inconspicuous area prior to use to determine proper use.

Q. Do I need to clean my grout before applying Spectrum’s Grout Stain?

A. Spectrum recommends that the grout joint be clean, dry and free of any dirt, grease or oil before applying the Grout Stain. Any neutral based cleaner will work to achieve this (scrub brush may be necessary).

Q. Can I use Spectrum’s Grout Stain over newly installed grout that has mottled in color?

A. This is a common problem in the grout industry and Spectrum offers a quick and inexpensive cure to this issue. With this in mind, though, Spectrum recommends you wait a minimum of 14 days after the installation to allow for sufficient hydration of the grout joint.

Q. If I don’t like Spectrum’s Grout Stain color I applied, can I stain over it?

A. Yes. Spectrum Grout Stain can be applied over itself to change an already stained color. Just remember, it may look painted on and if you are going from very dark to very light you may need to apply twice.

Q. How do I clean cured Spectrum’s Grout Stain off a grout joint if a mistake is made?

A. Any paint stripper for latex based paints will break down Spectrum’s Grout Stain. A gel type stripping product is recommended for accurate application, but use caution as paint strippers can cause harm to some surfaces. “Fully read and understand the instructions and hazards on any paint stripper product”.

Q. Is Spectrum’s Grout Stain a water clean-up product?

A. Yes. Water or water combined with a neutral based detergent works well to clean any application tools.

Q. What is the recommended application temperature for Spectrum’s Grout Stain?

A. For best results, apply Spectrum’s Grout Stain when temperatures are above 40°F and rising, but not above 95°F.

Q. How long does it take for Spectrum Grout Stain to dry?

Q. How long does it generally take to complete a Spectrum Grout Stain project?

A. With Spectrum Grout Stain's ease of use, most projects are completed in one day.
