Question 1

What kind of caulking gun do I need for the 600ml bag, and is it messy to use?**

Accepted Answer

You'll need a standard **sausage or bulk cartridge caulking gun** (not a standard tube gun). To prevent the common issue of nozzle clogging, we recommend cutting a smaller tip than you think you need, using a consistent pressure, and capping the nozzle immediately after use. A little prep goes a long way for a clean, professional finish.

Question 2

Is this sealant truly waterproof and mold-resistant for shower and bathtub use?**

Accepted Answer

Yes, the ILLBRUCK LD702 is a waterproof acrylic sealant suitable for wet areas like baths and showers. It contains fungicides to resist mold and mildew. For optimal performance in constantly wet, high-humidity environments, some professional users on forums suggest a 100% silicone sealant may offer longer-term flexibility.

Question 3

Can I paint over it, and how long should I wait before doing so?**

Accepted Answer

Absolutely. A key benefit of this acrylic sealant is that it can be painted over with most water- or solvent-based paints. For best results, ensure the sealant has fully cured. We recommend waiting **at least 24 hours** before applying paint, especially in cooler or more humid conditions where curing can take longer.

Question 4

The product title says "White." What shade of white should I expect?**

Accepted Answer

This sealant dries to a bright, clean, modern white. It's perfect for matching contemporary fixtures and new installations. If you are sealing older fixtures with a cream, almond, or off-white tone, it may be visually noticeable. For an exact match to older colors, you may want to plan on painting over it.

Question 5

How does this compare to more common tube sealants from hardware stores?

Accepted Answer

The 600ml bag format offers better value per ounce for medium to larger projects. In terms of performance, based on aggregated user reviews, it provides **superior adhesion and a durable, non-yellowing finish** compared to many basic acrylic caulks. The main difference is the application system, requiring the right gun. If you have a very small job, a standard tube might be more convenient.
