apel All Purpose Clear Silicone Sealant Waterproof - Durable Clear

In this review of the apel All Purpose Clear Silicone Sealant Waterproof, the bottom line is simple: it is a versatile, weatherproof 100% silicone caulk best suited for home DIYers and trade users who need a clear, flexible seal for indoor and outdoor gaps. The single biggest reason to buy is its combination of true waterproofing and UV resistance, which keeps seals clear and stable over time. The product is low odor and high viscosity, making it easier to apply on vertical surfaces without runs, and it is rain ready within 24-48 hours when clamped while curing.

Key Features

• 100% Silicone: Provides a weatherproof, flexible bond that resists yellowing and holds in place without shrinking or cracking.
• Low Odor: Formulated to avoid strong chemical smells so it is more comfortable to apply in enclosed spaces.
• High Viscosity: Thick consistency allows neat application on vertical surfaces without dripping for better control.
• Outdoor Safe: Designed to resist UV degradation so seals remain clear and durable when used outside.
• Easy Cleanup: Excess sealant can be removed with mineral spirits for a cleaner finish after tooling.
• Multiple Applications: Works well around sinks, showers, windows, and tile borders but should not be used on mirrors.

Who It's For

This clear silicone sealant is aimed at homeowners, handypersons, and contractors who need a reliable, flexible sealant for general-purpose indoor and outdoor sealing tasks. It is particularly useful where a transparent finish matters, such as glass, tile borders, and clear caulking lines around fixtures.

Those who require larger cartridge volumes per project or need a mirror-safe product should consider alternatives, since some buyers reported smaller-than-expected tube fill and the manufacturer explicitly warns against use on mirrors. For heavy industrial sealing tasks with specialized requirements, a product with different additives may be preferable.

Pros & Cons

Pros

• Strong adhesion and flexibility from a 100% silicone formula that resists cracking.
• Low odor makes it more suitable for indoor use than many solvent-heavy sealants.
• High viscosity leads to controlled application on vertical surfaces without sagging.
• Weatherproof and UV resistant, so it does not yellow quickly when used outside.

Cons

• Some customers found the cartridges partially filled or smaller than expected, which affects value for money on larger jobs.
• Not recommended for mirror installation, limiting one specific use case.
