100% silicone white sealant AX25WH 10.3 oz

100% Silicone White Sealant For Nonporous Surfaces

100% silicone white sealant in a 10.3 oz cartridge from the Axiom 25 line provides a dedicated option for sealing and fastening on nonporous materials, so installers can handle solid surface and similar jobs with a single consistent product. This silicone sealant is described as a silicone seal in white, which gives a neutral, job-site friendly color that blends into common bath and kitchen applications. The sealant is specified for use with all solid surface products, engineered stone, cultured marble and other nonporous surfaces, tying directly into typical fabrication and installation workflows around countertops, surrounds and vanities. As a silicone sealant product class, it is purpose-built for sealing joints and seams rather than acting as a general-purpose adhesive, which matters when clean, flexible joints are required on finished surfaces.

Key Silicone Sealant Details For Trade Work

• This Axiom 25 silicone sealant is specified for use with solid surface products, engineered stone and cultured marble, so fabricators can carry one white silicone across multiple premium surfacing lines on a project.
• The formulation is 100% silicone, which provides a pure silicone joint where that material type is required or preferred in bathrooms, showers and kitchen areas.
• The sealant is noted for use on other nonporous surfaces, letting installers bridge between sheets, trims and panels without changing sealant families.
• Once cured, the silicone is highly resistant to ultraviolet light, ozone, moisture, mildew and extreme temperatures, so exposed or wet-area joints maintain their function in service environments.
• The cured seal remains flexible and accommodates joint movement of plus or minus 25 percent, allowing for building movement and thermal expansion at seams around tubs, showers, windowsills and countertops.
• The product is not paintable and requires painting surfaces before sealing, which keeps the silicone itself acting only as a sealant and avoids later coating steps on the cured bead.

Installation Use Around Baths, Showers And Tops

This Axiom 25 silicone sealant is described for sealing sheets and strips for bathtub and shower surrounds, so installers can run continuous beads at vertical and horizontal seams where water exposure is routine. The same product is specified for fastening and sealing windowsills, providing a way to both secure components and close gaps around those sill areas. It is also indicated for fastening and sealing side and backsplashes to kitchen countertops and vanities, tying splash pieces to solid surfaces while closing joints against moisture. Because the silicone is stable through freeze and thaw cycles, it supports storage and transport conditions that may move between cold and warmer spaces before use, which is important on jobs that work through varying seasons.

Where This Silicone Sealant Excels In Use

Applications On Solid Surface And Nonporous Materials

This silicone sealant for solid surface is specified for use with all solid surface products, so it aligns directly with common shop-fabricated counter and splash systems. The same product is also specified for engineered stone and cultured marble, extending coverage across a range of cast and composite surfaces often found in baths and kitchens. Because it is also indicated for other nonporous surfaces, trades can use one silicone bead type as they transition from solid panels to trims, surrounds and similar components. The described uses include sealing sheets and strips for bathtub and shower surrounds, which matters when cladding wet walls where a tight seam helps control water. It is also called out for fastening and sealing side and backsplashes to kitchen countertops and vanities, letting the same material perform both bonding and joint sealing at these transitions.

Sealant Performance That Supports Joint Movement

This flexible silicone joint sealant remains flexible once cured, so the bead can move with the surrounding substrates instead of becoming rigid at joints. The joint movement rating of plus or minus 25 percent means the cured seal can accommodate expansion and contraction around tubs, showers, windowsills and countertops. Because the cured product is highly resistant to ultraviolet light and ozone, it is suited to joints that may see daylight exposure at windowsills or near exterior openings. Its resistance to moisture and mildew once cured supports use in bathtub surrounds, shower areas and around kitchen and vanity sinks, where damp conditions are standard. The sealant is also highly resistant to extreme temperatures once cured, which helps maintain joint performance when surfaces warm from sunlight or cool from ambient conditions. Freeze/thaw stability described as stable further supports handling, storage and use across changing temperatures on and off the job.
