RJ3.07   SHELTERCOATSe

PRODUCT DATA SHEET

DESCRIPTION

 Permeable lime-based materials for conserving or treating limestone, soft brick, calcareous sandstone and porous building materials which contain ingredients similar to the material to be treated.
Sheltercoatse are individually designed to match the material to be treated, and are sacrificial coatings with the primary function of protecting the masonry beneath. Properly applied to appropriate materials they prove durable in sheltered locations.

ENVIRONMENTAL CONSIDERATIONS

 Sheltercoatse are environmentally friendly products made with natural sustainable ingredients. They contain no VOC's, no petrochemical based ingredients, and no lead.
Water based.

USAGE/PURPOSE

 To be used primarily as a surface consolidant to soft, friable or laminating porous limestone. They can also used as a "surface finish" to unify or homogenise the appearance of masonry, especially after lime-based mortar repairs have been carried out.
For internal and external use.

SHELF LIFE

12 weeks. Store in cool environment.

COVERAGE

 Dependent on porosity and texture of surface to be treated, (approx. 2 - 3 square metres/litre/coat).

COLOURS

 Individually made to match colour material to be conserved.

PACKAGING

 5 litre cans and 15 litre tubs.

AVAILABILITY

 Direct from Rose of Jericho. Shcltercoatse are mixed to order.

FIRE RATING

 Non-flammable.

HEALTH AND SAFETY
INFORMATION

 

 Alkali pH 13. Eyes, open sores and cuts, and the skin should be protected. Detailed information is provided in Safety Data sheet RJ 5.03D.

NOTE: Those engaged in the usage and application of this product should ensure they obtain and read the above Data sheet.

Composition.
Non-hydraulic lime putty, stone-dusts, and fine sands, (and occasionally natural pigments). Lactic acid casein, a natural glue derived from milk, is added to improve adhesion and durability as the calcium caseinate formed is relatively insoluble. This does not affect permeability. As casein can promote the growth of algae, an algaecide and anti-microbial agent are added.

PERFORMANCE

Limitations: Do not apply in temperatures of 5ºC or below, or if there is a risk of frost.
As with all lime-based conservation materials, control of the drying process is essential. Protection and regular mist spraying with water to prevent over rapid drying and promote carbonation are necessary. Sheltercoatse carbonate and set by reacting with atmospheric carbon dioxide in the presence of moisture. They should not be allowed to dry before carbonating.

PREPARATION

Sheltercoatse cannot be applied to previously painted surfaces. Remove any existing paint physically if possible. If a chemical stripper is used, it must be properly neutralised as any residue of either stripper and/or neutraliser may affect the performance of sheltercoatse. Sheltercoatse require a surface which is clean and porous. Dusty, friable surfaces should be brushed free of loose particles. Heavily sulphated surfaces should be poulticed. Algae or mould should be treated with a fungicide or algaecide that does not contain water repellents. Always pre-wet the surface thoroughly and again with a mist spray immediately before application.

APPLICATION

Ensure Sheltercoate is within shelf-life period. Thorough mixing preferably with electric whisk is necessary before and during application as the solids readily settle out.
Experienced operatives familiar with the use of lime based materials should be employed. Application is determined by the porosity of the material to be treated and the intended result. Sheltercoatse are often applied in 2 or 3 coats, the first coat being sometimes diluted with clean water for very porous surfaces. Apply by brush, working in thoroughly. Second and third coats can be applied prior to the carbonation of previous coats. Dampen the surface with a mist spray between coats. Often, to avoid a completely homogenous finish, sheltercoats are wiped back from sound surfaces and "high spots" whilst still damp leaving the material in the hollows and pores. Use a sponge, or soft paint brush and the minimum of water.
