Prepare Surfaces and Select Caulk

What happens here

Before beginning the caulking process, ensure all previous surface preparation work is complete. This includes spackling any nail holes or imperfections in the baseboards and walls, and then thoroughly sanding those spackled areas until smooth. The speaker emphasizes sanding spackle *before* applying caulk to avoid damaging uncured caulk. Next, select an appropriate caulk for the job. The video demonstrates the use of 'Big Stretch' caulk, which is highly recommended for baseboards, especially in older homes where walls and floors may not be perfectly square or plumb. Its flexibility and low-shrink properties allow it to effectively bridge wider gaps without cracking over time.

Goal: Ensure surfaces are ready and the appropriate caulk is chosen for optimal results.
