Product Description

Phoscrete FORMULA-3 PRIMER

Phoscrete F3-Primer is a two-part cementitious MPC (Magnesium-Phosphate-Cement) concrete repair mortar composed of magnesium oxide, potassium phosphate, and aggregates (Dry Mix) that must be mixed with pre-measured Phoscrete Primer Activator.

Phoscrete F3-Primer is very rapid hardening with high-early strength gain, allowing fast completion of concrete repairs. It mixes to a putty consistency, is easy to apply by hand as a scrub-coat and is easy to trowel to a ¼ inch (½ cm) thin layer.

Phoscrete F3-Primer is recommended as a pre-treatment when installing Phoscrete Formula 1 (F1) for concrete repairs when the substrate contains reactive aggregates (notably limestone), and in high stress environments when maximum bond strength is desired & is ideal for preparing substrates for vertical, overhead, and horizontal concrete repairs, including expansion joints.
