Rockcote Marble

Rockcote Marble is a blend of selected marble and coloured pebble aggregates set in a 100% acrylic binder providing a protective and highly decorative finish for all masonry walls and ceilings. This product is suitable for both interior and exterior applications.

COMPOSITION

The acrylic binding system has been specifically developed to enhance the natural beauty of the selected aggregate and provide a long lasting, weather resistant, non-yellowing finish. A powerful fungicide is incorporated to inhibit defacement by mould and algal growth.

PERFORMANCE & PROPERTIES

Rockcote Marble is a flexible, long lasting, hard wearing coating, suitable for high traffic areas.

Colour Range

Available in a range of coloured aggregate consisting of marble chips and/or graded river pebbles of various sizes & colours. These may be blended to achieve the desired colour & effect. It is important to note that as colours change from different areas of the quarry where the natural stone is found, samples and all materials for a project should be ordered at one time, as subsequent batches may vary slightly in colour. Rockcote cannot accept responsibility for colour variances if this ordering procedure is not observed.

Size Range

Rockcote Marble is available in 2 basic chip sizes; 0.5 - 1mm and 1.5 - 3mm. The smaller size yields a “tighter” finish and in the larger size the individual chips are more defined. Care must be taken when requesting samples and ordering product to ensure the required chip size is specified.

Limitations

Rockcote Marble is not suitable for floors or fully submerged areas as some whitening may occur. It should be noted that the colour range is restricted to the aggregate available. Refer to previous note in “Colour Range”.

Note: As Marble Trowel-On is made-to-order, the lead time from order confirmation to the final product is dependent on the type of chip and availability of stock. Lead times can vary between three to six weeks.

SURFACE PREPARATION

All surfaces should be clean, dry and free from form release oil, grease or loose material. As some marble is slightly translucent, the surface must be an even colour before applying the marble. To achieve this, Rockcote Hi Opacity Primer is tinted to a colour matching the marble finish to be used. Apply 1 or 2 coats as required to achieve an even coloured background. For white Marble it is essential that a clean, even white background is achieved.

Concrete

Form joints & other surface imperfections should be patched using Rockcote Skimcote to achieve a flat, even finish before application of the Rockcote Primer. With white Marble and other lighter colours, Hi Opacity Primer is required to achieve a suitable background.

Bricks & Blockwork

Brick & block walls should be rendered using either Rockcote Skimcote or Rockcote Quick Render to achieve a straight flat surface before applying the Rockcote Hi Opacity Primer & Marble Finish.

Cement Sheeting

Cement Sheets should be fixed to the wall as per the manufacturers instructions. The joints are then set using the Rockcote Jointing System (refer Application Specification: Jointing System – Fibrous Cement Sheet )
Rockcote Polymer Render is then applied to the entire wall using a steel trowel and finished with a plastic float. A coat of Hi Opacity Primer is then applied (refer Surface Preparation).

COVERAGE
