Instruction guide and tips for resurfacing masonry walls using Sakrete Parging Mix.

How to Resurface Masonry Walls

Concrete blocks and poured concrete walls normally have a rough texture and require parging in order to create a smooth appearance.

SAKRETE Parging Mix is a pre-blended, ready-to-use, cernent mixture with superior bonding, specifically designed for finishing concrete blocks or poured concrete walls, above and below grade.Use to level imperfections up to 10 mm (3/8 inches) deep.Just add water and apply with a trowel.

Uses

For parging smooth and leveling imperfections on concrete blocks or poured concrete walls, above and below grade.

Use to level imperfections up to 10 mm (3/8 inches) deep.

lt may also be used on painted concrete and wood surfaces.

PROCEDURES: Mix and substrate temperatures should be maintained between 5 °C (40 °F) and 30 °C (86 °F) for at least 24 hours prier to and 48 hours after.

 STEP 1: Surface Preparation: Surfaces to be repaired must be structurally sound and clean. Remove all delaminated or unsound concrete by chipping with a hammer and chisel or using a stiff wire brush. Clean the area to be repaired with potable water, leaving the concrete saturated but free of standing water. Sorne very porous concretes may require several applications of water to ensure complete saturation.

APPLICATIONS TO CLEAN, SOUND, CONCRETE BLOCKS OR POURED CONCRETE

STEP 1: Thoroughly saturate the area to be parged and remove any free standing water. Sorne very porous concrete may require several applications of water to ensure complete saturation. After mixing apply SAKRETE Parging Mix, by trowel, to a damp surface not exceeding 10 mm (3/8 inches) in thickness. If a greater thickness is required, rough-up surface with a coarse broom and allow to harden for 24 heurs before repeating process.

STEP 2: Finishing: lt is recommended to use a wood, magnesium or aluminum float trowel for a smooth surface.For a textured surface, use a broom or brush.

STEP 3: Curing: Allow newly placed material to set until surface is hard to the touch. Then keep material damp or cover with plastic to prevent evapouration of mix water for at least three (3) days. Protect from freezing for at least 24 hours. 

APPLICATIONS TO LOOSE, UNSOUND OR PAINTED CONCRETE AND WOOD SURFACES

STEP 1: Mechanically fasten galvanized, diamond-wire mesh to surface. Wood surfaces require 6.8 KG (15 lb) of asphalt-impregnated building paper under mesh. Dampen exposed concrete.After mixing, apply initial layer of SAKRETE Parging Mix, by trowel, level with mesh surface. Rough-up surface with a coarse broom and allow to harden for 24 hours. Then, thoroughly saturate the area with clean water and apply a finishing layer to a damp surface not exceeding 10 mm (3/8 inch) in thickness.

STEP 2: Finishing: lt is recommended to use a wood, magnesium or aluminum float trowel for a smooth surface.For a textured surface, use a broom or brush.

STEP 3: Curing: Allow newly placed material to set until surface is hard to the touch. Then keep material damp or cover with plastic to prevent evapouration of mix water for at least three (3) days.Protect from freezing for at least 24 hours

Tips for working with SAKRETE Parging Mix:
  1. Apply to a damp surface.
  2. Applications should not exceed 10 mm (3/8 inches) in thickness.
  3. Cure after applying by keeping damp for 72 hours.
  4. Use proper safety equipment (i.e. safety glasses, gloves, etc.).
