Sand Topping

SGM Sand Topping is a professional-grade, ready-to-use sand and cement mix crafted specifically for surface repair and preparation tasks. It serves as a dependable solution for patching concrete, filling cracks, and topping uneven areas between 0.5 and 2 inches in depth. Beyond mere repair, it can function as a solid mortar base under ceramic tile or dimension stone, ensuring a strong and stable foundation for installations.
What makes Sand Topping particularly valuable is its simplicity. The mix is pre-blended, meaning no need for tedious measurement or mixing of separate components. Installers only add clean potable water, typically between six and nine pints per 60-pound bag, to achieve a plastic, trowel-ready consistency. This streamlined process reduces jobsite waste, lowers labor time, and delivers consistent quality with every application.
Before applying Sand Topping, surface preparation is essential. Substrates must be clean and free of foreign matter, grease, paint, and oil to ensure adherence. When applying over existing concrete or masonry, a concrete bonding agent should be used first to improve mechanical bonding. Installers should also avoid covering expansion, cold, or control joints, and adhere to TCNA Handbook method EJ171 for detailed installation guidance.
Coverage is efficient: one 60-pound bag covers approximately 14 square feet at half-inch thickness. Cure times vary based on ambient conditions, so care should be taken to allow appropriate drying before proceeding with further work. Cleanup is effortless, tools and hands can be washed with warm, soapy water while the material is still fresh.
Safety is critical when handling cement-based products like Sand Topping. The mix becomes alkaline on contact with water and contains free silica, which poses inhalation risks. Installers must avoid skin and eye contact. Eye exposure should be addressed by flushing with water and seeking medical attention. To minimize silica dust inhalation, use a NIOSH-approved respirator. These precautions ensure safe handling and regulatory compliance.
The shelf life for Sand Topping is up to 12 months when stored in unopened, properly maintained containers, offering flexibility for inventory and project planning. SGM stands behind the product with a one-year warranty from the date of manufacture, covering materials that do not perform as intended under normal use. Claims require written notice and samples of the product in question.
In the hands of professionals, SGM Sand Topping is more than a patch, it is a high-performance surface preparation tool. Its versatility makes it suitable for quick fixes or complex substrate rebuilding. When used correctly, it helps create flat, smooth bases essential for durable tile or stone installation. Contractors can trust that the quality of this pre-blended mix supports precision, efficiency, and long-term results.
