QUIKRETE Mortar is not suitable for horizontal surfaces; It lacks the strength to withstand even foot traffic. For your application, we recommend QUIKRETE Sand/Topping Mix #1103. This high strength mortar can be placed in a thin bed and can accept rubber stamping.
QUIKRETE® Greencore Type S mortar is suitable for all above grade load bearing assemblies requiring a Type S mortar. Please consult local building code to determine whether your application requires a Type S masonry mortar.
No, QUIKRETE® Mortar Mix Type S should not be used inside the firebox. Portland cement, the base material out of which standard mortars are made, can degrade in temperatures as low as 200 degrees F. Because of this, products used within the firebox of a fireplace, or near high temperatures, should be made of refractory cement, which is designed to be able to withstand exposure to high temperatures, rather than Portland cement. For repairing damaged firebrick and tuck-pointing damaged fireplace mortar joints, you may consider QUIKRETE® Fireplace Mortar (No. 8620-21). For new installations of fire bricks you will want to purchase the specified refractory mortar.
We recommend QUIKRETE® Sand/Topping Mix (No.1103) with QUIKRETE® Concrete Acrylic Fortifier (No.8610) replacing half of the required water content for the mortar base for a tub. ANSI 108.1 provides application and material requirements for shower pans and bathtubs. It is critical that the subfloor / structure underneath be rigid. Please consult and follow local building /plumbing code requirements, which typically require the installation of a waterproof membrane. Type S Mortar should not be used for shower pans.
