4.4 L (1.2 US gal) of clean, potable water / 30 kg (66 lb) bag

Between 5 °C (40 °F) and 30 °C (86 °F)

Approx. 5.3 m² (57 ft²) per 30 kg (66 lb) bag, applied at a thickness of 3 mm (⅛ in). Coverage rates may vary according to the profile of the surface to be covered.

Mix and substrate temperatures should be maintained between 5 ºC (40 ºF) and 30 ºC (86 ºF) for at least 24 hours prior to and 48 hours after.

MIXING:

Start by pouring 4.3 L (1.2 US gal) of clean, potable water per 30 kg (66 lb) bag in a clean container. Gradually add the dry ingredients while mixing with a drill fitted with a mortar-mixer. Mix for about 4 minutes, making sure to scrape down the sides of the container to obtain a homogeneous mixture with a slightly flexible consistency. If the mixture is too thick, add a little water at a time, taking care not to thin it out too much [the maximum amount of water is 4.4 L (1.2 US gal) per 30 kg (66 lb) bag]. The consistency of the product applied may vary according to weather conditions and the porosity of the surface.

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. Some very porous concretes may require several applications of water to ensure complete saturation.

• Placing: Application to clean, sound, concrete blocks and poured concrete, proceed to Surface Preparation 1. Application to loose, unsound or painted concrete and wood surfaces, proceed to Surface Preparation 2.
• Surface Preparation 1: Application to clean, sound, concrete blocks and poured concrete. Thoroughly saturate the area to be parged and remove any free standing water. Some very porous concrete may require several applications of water to ensure complete saturation. After mixing apply Sable Marco® Parging Pre-mix, by trowel, to a damp surface not exceeding 13 mm (½ in) in thickness. If a greater thickness is required, rough-up surface with a coarse broom and allow to harden for 24 hours before repeating process.
• Surface Preparation 2: Application to loose, unsound or painted concrete and wood surfaces. 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 Sable Marco® Parging Pre-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 13 mm (½ in) in thickness.

FINISHING:

To obtain a smooth surface, we recommend using a wooden, magnesium or aluminium float. To obtain a textured surface, use a broom or brush.

Curing involves maintaining the right temperature and humidity levels. Wait for the new material to set, until the surface is hard to the touch. Then keep the material damp or cover it with a polyethylene sheet to prevent the mixing water from evaporating for at least 3 days. Protect from frost for at least 24 hours.

 Clean all tools and equipment immediately after use with water. Once hardened, material can only be removed manually or mechanically.
