We'll cover choosing the right grout, prepping the surface, steps for the repair process, tips to make the job easier, and common mistakes to avoid. With the information in this article, you'll be able to breathe new life into your shower and make it look brand new.
Choosing the Right Grout
When repairing cracked grout, it's important to choose a grout that matches the existing color and texture. The two main types of grout are sanded and unsanded:
- Sanded grout contains fine sand particles and is best for wider grout lines (1/8 inch or larger). It provides a rough texture that holds firmly in place.
- Unsanded grout has a smooth finish and is ideal for narrow grout lines. It resists shrinking and cracking.
For showers, most experts recommend sanded grout because it stands up well to moisture. An epoxy-based grout is another excellent option, especially for frequently used showers. Epoxy grout is more durable, stain resistant, and waterproof.
Take a look at the existing grout color and texture before purchasing materials. Having an exact match will provide a seamless finished look.
Preparing the Surface
Before applying any new grout, it's important to make sure the surface is clean and ready. Here are the key steps:
- Use a grout saw or grout scraper tool to remove all loose, cracked, or crumbling existing grout. Remove it down to the bottom of the grout line.
- After removal, thoroughly vacuum up any debris or dust left behind in the grout lines or tile crevices.
- If there are any remaining stains or discoloration, apply a mild acid-based cleaner to the grout lines. Let it sit briefly before rinsing.
The goal is to get down to a sound, clean foundation so the new grout bonds well. A surface free of contaminants will help your finished repair last much longer.
Tools You'll Need
Having the right tools on hand will make grout repair go faster and smoother. Here are the must-have supplies for DIY grout repairs:
- Grout in the matching color
- Grout float for application
- Grout saw or scraper
- Shop vacuum to clean surface
- Mild acid cleaner (if needed)
- Grout sponge
- Two buckets - one for mixing, one for cleaning
- Old rags or cheesecloth
- Rubber gloves and safety goggles
For epoxy grout, you'll also need the epoxy resin and hardener. Gather all materials and tools beforehand so they're ready to go.
Step-by-Step DIY Repair Process
Once you have the right grout and supplies, you're ready to move onto the repair process. Follow these key steps:
Step 1 - Remove Old Grout
Use your grout saw or scraper to remove all of the old, damaged grout down to the bottom of the grout line. Try to remove it evenly across all grout lines. Take your time to do this thoroughly, as it's the most important prep step.
Step 2 - Clean the Surface
After removal, vacuum all the grout lines and crevices to remove dust and debris. Then use a mild acid cleaner if needed to remove any remaining spots or stains. Rinse thoroughly with clean water.
Step 3 - Mix the New Grout
Mix up a small batch of your new grout per the manufacturer's instructions. Only mix up what you can use in 30 minutes. Don't let premixed grout sit too long. For epoxy grout, carefully measure and mix the resin and hardener as directed.
Step 4 - Apply the New Grout
Use your grout float to apply an even layer of grout over the entire surface, forcing it down into the grout lines. Hold the float at a 45-degree angle and apply in a scraping motion. Completely fill the lines and spread smoothly.
Step 5 - Wipe Away Excess Grout
Let the grout sit for a few minutes until a haze forms on top. Then use a damp grout sponge in a circular motion to wipe the excess grout off the tile. Rinse out the sponge frequently. Use as little water as possible.
Step 6 - Let the Grout Cure
Allow grout to fully cure according to manufacturer directions before using the shower (usually 24-72 hours). The longer you allow curing, the stronger it will be. Avoid moisture during this time.
Tips and Tricks for Easier Repair
Follow these handy tips and tricks for a smoother grout repair process:
- Work in manageable 3-4 foot sections so grout stays workable.
- Take your time applying grout to fill all voids and gaps.
- Don't overwork the grout or remove too soon. Let it set up.
- Consider sealing the grout after repairs for added moisture protection.
- Choose epoxy grout if the area will get wet often.
Common Grout Repair Mistakes
Avoid these common missteps when tackling DIY grout repairs:
- Not fully cleaning the old grout before application.
- Applying grout unevenly or not packing it firmly into gaps.
- Not allowing the full curing time before exposing to water.
- Using too much water when mixing grout.
- Forgetting to seal the grout after repairs are complete.
Renewing the grout in your shower is a straightforward DIY project that can give your whole bathroom a facelift. While cracked, stained grout can make a shower look dingy, fresh grout lines look crisp and clean.
