ARDEX SG is a high-performance smoothing agent specifically formulated for use with ARDEX silicone sealants. This professional-grade lubricant prevents silicone from adhering to application tools and surrounding surfaces, ensuring a perfectly smooth, clean, and professional finish for every joint.
ARDEX SG is intended for use during the tooling phase of silicone application. For best results, spray the agent onto the tool or the joint after the silicone has been applied. Important Note: Do not apply to joints before silicone is injected, as this will prevent proper adhesion. Avoid use on porous substrates, such as natural stone or unglazed tiles, to prevent potential staining.
