A homeowner needs to fill a 5mm+ gap behind bathroom tiles before sealing with silicone, but cannot do a full renovation.
Existing products (backer rod and silicone) are generic and require careful manual application; there is no dedicated kit or easy-to-use product specifically designed for filling large gaps in wet areas before sealing.

The foam expands to fill irregular gaps, and the silicone is formulated for high-humidity environments.
Key Features
- Pre-measured foam backer strip with integrated silicone sealant cartridge
- Applicator gun with precise flow control
- Mold-resistant, silicone-based sealant suitable for wet areas
- Foam expands to fill gaps from 3-10mm
Target Users: Homeowners and DIY enthusiasts performing bathroom repairs and maintenance, especially in older homes with gaps behind tiles.
Revenue Model: $15-$25 per kit (single-use applicator + foam/sealant combo), sold at home improvement retailers and online
