The Seal Around the Edge

A narrow line of silicone around a bath. A cracked grout joint in the shower. A gap behind the kitchen sink. Small details that are easy to overlook until water begins reaching places it should never go. The Seal Around the Edge takes readers inside the everyday world of silicone, caulk, grout and the joints that help protect a home. With clear explanations and practical guidance, Etienne Psaila explores how these familiar materials work, why they fail and how to recognise when a simple repair is appropriate. Discover the differences between sanitary silicone and paintable caulk, understand why grout is not waterproofing, and learn what matters when removing old sealant, preparing surfaces and applying a controlled bead. From bathrooms and kitchens to window frames, doors and exterior joints, the book explains the importance of adhesion, movement, moisture and choosing the right material. Just as importantly, it reveals why some gaps must remain open and why a fresh line of silicone cannot solve every leak. Written for homeowners, DIY beginners and anyone who wants to understand the small barriers around a property, this is a practical guide to making better maintenance decisions, avoiding common mistakes and knowing when professional help is needed.
