Using the Right Caulk for the Job

Welcome to our easy guide on how to use caulk or sealant! Our Technical Services team is here to guide you through several important considerations for using caulk for different areas in your home.

Consideration 1: Drying Time

When choosing caulking, the drying time is crucial to consider. Faster-drying caulk is ideal for quick return to service and immediate use, while slower-drying products allow more time for application and smoothing. Understanding these differences helps ensure a successful, long-lasting seal for your home improvement projects.

How Long Does Caulk Take to Dry? 

The drying time of caulk depends on the type of caulk and the ambient conditions during installation. Always apply caulk within the recommended temperature range, typically between 40°F (4°C) and 90°F (32°C). 

• LATICRETE^®  Premium Acrylic Caulk: Sets in 48 hours and fully cures in 2 weeks.
• LATICRETE LATASIL™ 100% silicone caulk:  Sets in under 20 minutes and fully cures in 24 hours. For continuous water submersion (like pools or fountains), allow 4 days to cure and use LATASIL 9118 Primer. 

Consideration 2: Job Type

Different projects require specific caulk types for optimal performance, such as choosing an anti-microbial caulk for bathrooms or flexible silicone caulk at corners and changes of plane. Selecting the right caulk ensures durability and effectiveness, tailored to the needs of your specific task.

How to Caulk a Shower or Bathtub

When caulking around a shower or bathtub adjacent to tile or stone, the first step is choosing the right caulk for the job. We recommend LATASIL 100% Silicone Caulk.  After you’ve chosen your caulk, follow these best practices for a smooth, professional look:

1. Select a 100% Silicone Caulk: A 100% silicone caulk is best for caulking bathtubs and showers offering the greatest durability
2. Clean the area: Remove all dirt, dust, and old caulk from the joints.
3. Tape the joint: Apply masking tape to each side of the joint to ensure a clean, crisp line and prevent caulk from spreading onto surrounding surfaces.
4. Apply the caulk: Fill the joint completely with caulk.
5. Smooth the caulk: Use a gloved finger or a smoothing tool to even out the caulk within 5-7 minutes.
6. Remove the tape: Immediately after smoothing the caulk, remove the tape and allow the caulk to dry.
   

Conclusion

Understanding the proper application and curing times of different types of caulk is essential for successful installations in areas like bathtubs and showers. Whether you choose LATICRETE Premium Acrylic Caulk for interior projects or LATASIL 100% Silicone Caulk for moisture-prone areas, following specific preparation and application guidelines ensures optimal performance and durability. By adhering to these practices, you can maintain the integrity of your installations and achieve professional-looking, long-lasting results.
