Rockcote PM100

Rockcote PM100 is a pre-blended polymer modified cement render manufactured to exacting specifications from high quality materials. PM100 only requires the addition of clean water and mixing before application. PM100 is suitable for machine application or traditional Hawk and Trowel hand application.

Properly cured PM100 exhibits minimal drying shrinkage and is a reliable surface for over-coating with acrylic textures and paints.

Rockcote PM100 meets the requirements of the professional tradesperson and the demands of modern construction materials and methods.

PERFORMANCE & PROPERTIES

Rockcote PM100 is manufactured under controlled conditions. Consistent quality is assured.

Composition

Rockcote PM100 is composed of high quality, washed and graded sand, Portland Cement conforming to Australian Standard 3972 and proprietary additives. Application properties, adhesion, water resistance and consistency of product blend are all superior to site blended sand and cement render.

Time and Cost Savings

PM100 is quicker to apply than standard cement render. Rockcote PM100 requires less clean up and greatly reduced curing time before the application of finish coats. Under normal conditions, the application of Rockcote acrylic paint or texture coatings may be commenced two days after PM100 has dried if the PM100 is fully cured and moisture content of the PM100 is less than 15% WME. ^ Rockcote PM100 should not be left uncoated for an extended period of time and should be painted with an acrylic primer or Rockcote Armour as soon as practicable within 28 days after being fully cured.

Rockcote PM100 is suitable for machine application, which can further increase the speed of application.

Water Resistant - Rockcote PM100 is water repellent, reducing the risk of efflorescence or rising damp.

Adhesion – adheres well to standard and difficult masonry substrates such as bricks, concrete blocks, Hebel, Off-Form Concrete and specified lightweight building substrates (see Rockcote Application Specifications).

APPLICATION

Surface Preparation

• Rockcote PM100 should only be used over dimensionally stable masonry substrates.
• All surfaces must be clean and free from dirt, dust, oil, grease, silicone or loose materials before application.
• Large hollows and deviations in the surface are first filled and screeded with PM100 prior to application of the final coat
• Dry masonry surfaces must be wetted with clean water. Do not apply PM100 until the wet look has receded and the surface has absorbed the free water.
• Low suction substrates such as smooth concrete or smooth bricks should be treated with a “key” coat prior to the application of the render after being cleaned. The key coat is prepared by mixing PM100 into slurry with 25% Acrybond in the gauging water and applied to the wall with a spray-gun, sponge, brush or roller. This coating should be allowed to dry for 24 hours before applying thePM100.
• Over highly porous surfaces such as (A.A.C. Hebel), seal first with one coat Rockcote Acrybond mixed with an equal part of water to control suction and improve adhesion.

Rockcote PM100 can be applied by traditional Hawk and Trowel or machine (See table).

It is important to mask up all surrounding surfaces before rendering to avoid contact with PM100 especially aluminium window frames and glass.

Acrylic Finishing Coats

Rockcote PM100 has been specifically formulated without the addition of hydrated lime and is readily over coated with acrylic paints, texture finishes and lime washes after 48 hours if properly cured and containing less than 15% WME moisture content.

Before application of acrylic texture finishes the dry PM100 surface should have moisture content of less than 15%WME and be sealed with one coat of Rockcote Masonry Primer, Hi-Op Primer or EcoStyle Sealer/ Undercoat.

LIMITATIONS

• Should not be applied over cement sheet or previously painted surfaces not specified by Rockcote.
• Should not be applied in temperatures below 3 OC or in very hot and windy conditions or above 30 OC.
• Protect from freezing temperatures for 24 hours after application.
• Protect from heavy rain for 8 hours after application.

STORAGE, SAFETY and HANDLING

Refer to Rockcote MSDS for PM100

• Rockcote PM100 must be kept dry during transportation and storage.
• When working with Rockcote PM100, observe the usual precautions for handling cement based products.
• Avoid inhalation of the powder, prolonged skin contact and particularly eye contact.
• If contact occurs, flush thoroughly with clean water.
• Wear protective clothing to minimise skin contact and wear goggles where spatter is likely.
• Where spills occur, sweep up dry material or soak up liquid spillage with sand/sawdust and remove to suitable disposal.
• Clean up equipment and area with water. Do not permit run-off to sewer, storm water or open bodies of water.

The application of Rockcote PM100 is a specialist procedure and should only be carried out by a skilled and experienced applicator.
