How to seal tile grout in a shower step by step
1: Work in a safe and well-ventilated area
Before starting the sealing, make sure that the shower or bathroom is well ventilated.
We also recommend that you wear personal protection equipment including gloves, eye protection and suitable vapour mask.
2. Apply the shower grout sealer
Shaking the can well before use, now spray approximately 25 to 40cm from the tile and grout surface.
Apply the product evenly with sweeping side to side, up and down motions to the grouting.
Make sure any overspray is wiped off the surface of any tiles or sanitary wear with a damp cloth as you go along.
Do not allow the sealer to dry on these surfaces and it will make it more difficult to remove.
3. Let the shower tile grout sealer dry for up to 2 hours
Let the grout sealer dry in the shower for one to two hours.
4. Test an area using water droplets and apply second coat
Once fully dry do a test area after application using water droplets. If the water droplets are absorbed within 60 seconds, then apply a second coat repeating the same application process.
5. Let dry for at least 8 hours
Finally let the shower wall or floor grout to dry for a minimum of 8 hours before getting this area wet and using the bathroom again.
