Saturated Surface Dry & Grout Placement

Surface Preparation

Surfaces to be grouted should be clean and free from rust, dirt, grime, oil, curing compound and any other contaminants that will inhibit the bond of the cementitious grout. Determine method of placement and form area to be grouted. All forms should be sprayed with a SpecChem form release agent prior to placement. Forms should be caulked at all seams. Surface should be saturated surface dry (SSD). Remove excess or ponding water prior to placing grout.

Mixing Procedures

Add the appropriate amount of clean, potable water for the batch size and then add the dry grout. Mix for a minimum of 3-4 minutes. Small quantities of grout can be mixed with a “drill and jiffy mixer.” Larger quantities should be mixed with a paddle blade mortar mixer. The mixed grout should be transported to the grout head boxes are typically used for flowable or fluid grouts, while dry pack grouting does not require a head box.

Placing Procedures

Place all grout from one side to assure complete filling of the space being grouted. If necessary, use a rod or strapping to assist in placement of large or difficult applications. If pumping grout, pumping should be continuous and uninterrupted.

Curing Procedures

All grout must be cured immediately following placement. Grouts may be cured by ponding with water, covering with wet rags or burlap, or applying a SpecChem curing compound such as Cure & Seal 25, Cure & Seal WB, or SpecRez.
