Oatey HARTUBSEALWHT Water Based Siliconized Caulk White 5.5 Fl-oz Tube

Product Description

The Oatey HARTUBSEALWHT is a water based siliconized caulk designed for sealing and weatherproofing applications across a wide range of surfaces. This product comes in a 5.5 fl-oz tube and delivers a white, paste-form sealant that bonds to brick, ceramic, vinyl, aluminum, wood, glass, china, and metal. It is a trusted choice for plumbers, HVAC technicians, and general contractors who need a reliable, flexible sealant that performs on multiple substrates without requiring solvent-based cleanup. The water based formula keeps VOC content low at just 37 grams per liter, making it a suitable option in environments where air quality and compliance with low-VOC regulations matter. Siliconized caulks like the HARTUBSEALWHT combine the flexibility and moisture resistance associated with silicone with the easy application and paintability of a latex-based product. This makes it well suited for use around tubs, sinks, plumbing fixtures, window frames, door casings, and other areas that are exposed to moisture or temperature changes. The caulk dries to the touch in as little as 30 minutes, allowing work to continue without long wait times. Full curing takes 72 hours, after which the sealant reaches its final strength and flexibility. With a flash point above 93.3 degrees Fahrenheit and a flammability rating of 1, this product is considered low-hazard for storage and handling in standard trade environments. The white color blends cleanly with bathroom tile, trim, and plumbing fixtures, making it a practical finish-quality sealant for residential and light commercial jobs. Professionals who work on bathroom remodels, fixture installations, or general weatherproofing projects will find this caulk to be a dependable, multi-surface solution that is easy to apply and clean up with water.
