Buying Guide
What grout size does each pen suit?
5mm tips are ideal for narrow lines found in most wall and floor tiles. Wider 15mm tips accelerate coverage on large joints but sacrifice precision. For mixed projects, keep a 5mm pen on hand and reserve the wide-tip pen for broad areas.
Is waterproofing important?
Yes. Waterproof or water-resistant formulas help prevent color washout in bathrooms and kitchens. Consider a pen advertised as waterproof for longevity in damp environments.
How many rooms can a set cover?
Ink coverage varies by brand, but many 7mL pens claim up to 150 feet of 2mm grout. If you’re refreshing multiple rooms, a multi-pack can be more cost-effective and reduce reorders mid-project.
What about tips and replacement parts?
Look for pens that include extra tips or a backup nib. This helps if tips wear down or clog in high-use areas. Proper storage keeps tips dry and ready for next use.
How difficult is application?
Most grout pens are designed for simple “shake, press, draw” operation. Start with a dry, clean grout line, apply evenly, and wipe excess with a damp cloth for crisp edges.
Which product is best for beginners?
A standard 5mm tip pack with a single color is typically the easiest to learn with. It offers controlled lines and clear coverage without overwhelming first-time users.
Maintenance tips
- Allow painted grout to dry fully before cleaning nearby tiles.
- Avoid over-saturating grout to prevent color bleed on adjacent tiles.
- Store tips upright and away from moisture to extend life.
Who should consider these products?
DIY homeowners looking to refresh grout quickly, renters who need temporary or removable solutions, and tile enthusiasts seeking a crisp, retrofitted grout look without professional tools.
