ANSWER. ANSWER - It is possible to grout over existing grout if there is enough depth to do so. 1/8 inch depth may or may not be adequate depending on the type of grout used. A latex modified grout may work, but you have to properly clean the existing grout to ensure the new grout adequately bonds.
What's more, if water or grit gets into the joints of the tile, it can lead to serious problems. At this point you may wonder if a complete re-grout is necessary or if it would be possible to simply put new grout over old grout. The answer is, yes, it is possible to put new grout over old grout.
Regrouting a shower is more cost-friendly than replacing shower tiles entirely. It's worth regrouting a shower that needs a little TLC because grout helps protect your bathroom from mold and mildew.
ANSWER. ANSWER - It is possible to grout over existing grout if there is enough depth to do so.
If you try adding new grout over your old grout, the new mixture will not properly adhere to the existing grout or tile edges, leaving your shower open to water damage.
Do I have to remove all old grout before regrouting? Yes and No. If the old grout is mouldy, cracked and discoloured you can invest in the best grout cleaner to see what the grout looks like after cleaning. If a clean makes little difference it makes sense to remove as much grout as possible.
Shower regrouting done by a professional company will typically take a day to each shower and the cost can range from $900 to $1800 depending on the skills of the contractor, the materials used and the size of the shower.
Regrouting costs depend on the size of your shower. On average, expect to spend $10 to $25 per square foot if you hire a pro. The standard shower stall is 36-by-36 inches with a height between 72 and 80 inches. Tub-to-shower conversions are around 36-by-60 inches.
Cracked and dirty grout does not mean you have to pull all the tiles off the wall and start from scratch – replacing the grout alone is actually a relatively quick and simple job.
The grout should be dug out a minimum of 3mm deep (preferably deeper) so that new grout can have a firm base and a larger surface area of the sides of the tiles to adhere to.
When Should You Regrout Your Tile? Grout doesn't last forever. You can expect a lifespan between eight and sixteen years. Its lifespan will vary depending on how you treat your shower.
Moisture and direct water contact contribute to grout deterioration over time, and eventually, the tiles will crack. This is why you should consider regrouting shower tiles every six months. This is a quick and budget-friendly fix that can restore your bathroom's previous glow immediately.
Is Regrouting Difficult? Regrouting a bathroom shower or tub stall may seem difficult, but it really is just grunt work. The process is relatively simple and an entire shower regrout can usually be finished in about a day – even by someone who has never grouted tile before.
Yes, really! Re-grouting your tiles is an affordable and quick way of bringing your kitchen or bathroom back to life. Our easy-to-follow guide will show you just how simple it is to re-grout your existing tiles and freshen up your space.
Regrouting is a two-step process by which you first remove the hardened old grout from the seams, or joints, between tiles with an oscillating tool and some manual scraping. Then, you mix up some new grout and apply it to the tile with a grout float and clean it up with a sponge.
Manual tools can be used with a scraping, chipping, or sawing motion to cut through the hardened grout, but if you don't want to spend a lot of time and energy, you can also use an electric grout remover, rotary tool, reciprocating saw, or an oscillating tool.
