As the grout in shower is typically made from cement and sand, it naturally can absorb water. If you’re experiencing dirt, grime and stains in the tiles, frequent changing of the grout, molds in the shower wall, it’s because your shower grout is not capable of resisting air and moisture.
Seal grout in shower
Grout sealant in shower works really well to prevent any potential or severe damage of the grout and tiles. It gives a longer lifespan to the tiles and provides a bright new looking outlook. Moreover, it also resists growing any kind of microorganisms like bacteria or mold from the tiles and walls.
The grout in the shower should be sealed to make it water resistant and to keep the microscopic pores of the tiles from splitting. Molds thrive on moist surfaces, and water can seep into the grout during showers.
Therefore, sealing is also efficient in keeping microorganisms from growing on the shower wall. When new grout is placed in the shower, it is usually advisable to use sealant two or three days later for better locking. Furthermore, using sealant will improve the appearance of the shower tiles by creating a more shiny surface. So the only method to ensure that the tiles last a long time is to seal them.
In general, unsanded grout does not require sealing, but some people like to do so. Cement-based grouts typically require sealant because they have pores that can retain water and weaken the grout over time. Unsanded grout, on the other hand, is made of epoxy or polymer and is non-porous, allowing it to be utilized without sealant. Because unsanded grout is less likely to crack, some people prefer not to add a sealant on top of it to save money.
It’s important to seal new grout. New grout has to dry promptly before it can be sealed. If the new grout is cement-based, it takes around 3 days for it to fully cure before it needs to be sealed to prevent cracking and limit porosity.
To ensure that tile grout lasts as long as possible, it is usually necessary to seal it. Whether to seal the tile grout is up to the owner’s discretion. Cement-based tile grout is more likely to require sealing than synthetic tile grout.
Sanded grout should be protected since it can fade over time and increase the chance of water getting into the grout and dampening the surface. It also raises the possibility of cracks forming in the shower, so it should be sealed.
When to seal grout in shower?
Grout sealing does not have a defined schedule, but the state of the shower wall will dictate when it should be done. If the grout is flaking out and the color is fading, a stain on the shower tiles is the most obvious sign that it’s time to seal it. If the damage to the shower tiles is severe, it is usually recommended to seal the grout once a year. If the damage to the shower tiles is severe, it may be necessary to seal them earlier, usually six months a year.
But if you see cracks in the shower tiles, it’s time to re-seal the grout. Because grout is a porous material, water can easily penetrate it if it is not sealed, causing damage to the shower wall. You’ll need to re-seal the grout if there’s any damage to the outside of the shower wall or mold growth.
How often should you seal grout in shower?
The condition of the grout and the elements used to make the shower grout will determine how often it has to be sealed. Sealing it every year or within six months of the prior time is usually suggested. If the shower is prone to mold growth or displays signs of cracking or flaking, it should be sealed as soon as possible. If the shower grout is composed of cement, it may need to be sealed more frequently, usually every six months.
However, if the grout is made of polymer or epoxy, which is not porous by nature, there is less possibility of water entrapment and dampness. So, waterproofing the shower tiles once a year is a good idea to keep them stain-free. If the shower tiles are not sealed once a year, there is a greater danger of future deterioration and a higher cost of restoring all of the damage.
