Adhesives and Sealants — FAQ
What's the difference between silicone and stainless steel tips?
Stainless steel scrapes away old, hardened caulk aggressively. Silicone pads shape fresh caulk into smooth beads without scratching surrounding surfaces. Pros need both: steel for removal, silicone for finishing.
How many radius options do I need?
Most contractors use 3-4 radius sizes regularly. A 1/8" radius works for tight corners, 3/16" for standard tile joints, and 1/4" to 1/2" for larger gaps. Kits with 6+ options offer maximum flexibility.
Can these tools remove old caulk?
Stainless steel scrapers excel at removal. For best results, heat old caulk with a heat gun first, then use the steel edge to lift it in long strips. Dedicated removal tools have sharper angles for this task.
Are multi-tool kits worth the investment?
For contractors doing varied work, yes. A 5-in-1 kit replaces $75+ in individual tools and reduces weight. If you only caulk standard tile joints, a single $10 tool may suffice.
How do I clean and maintain my tools?
Wipe silicone pads with mineral spirits immediately after use. Soak steel scrapers in solvent to dissolve buildup. Store tools flat or hung to prevent pad deformation. Replace silicone pads when edges fray.
What's the best tool for window glazing?
The Finish Line Precision tool excels here. Its syringe applicator and micro-fine tips allow precise placement of glazing compound without smearing glass. For large panes, use a flat silicone pad at a 45-degree angle.
