Working in hot conditions

The primary concern during hot weather is the evaporation of water from

the mortar and a reduced board life. If sufficient water is not present, the

bond between the mortar and brickwork may be reduced. Readymade

tubs should be kept covered and all material, equipment and mortar

boards kept in the shade at all times. Tubs and mortar boards should also

be rinsed with cool water before they come into contact with the mortar.

Under hot, dry and windy conditions bricks and blocks should be laid

more rapidly after placing the mortar. It is also recommended that newly

laid masonry is protected against rapid drying by covering with

damp hessian or similar sheeting in extreme conditions.

Working in cold conditions

Mortar strength generally occurs at temperatures over about

4C. Therefore it is recommended not to lay masonry when the

temperature falls below this as the characteristics may be affected,

especially during periods of freezing conditions.

Mortar tubs should be adequately covered to provide protection against

rain, frost and snow. During prolonged periods of very cold weather, it is

best practice to store the material away. Do not use mortar that contains

ice particles or lay mortar on frozen surfaces.

All bricks and blocks should also be adequately covered to provide

protection against rain, frost and snow. Masonry that is saturated should

not be laid, or when there is a danger of freezing.

As mortar hardens more slowly in cold weather, all newly laid masonry

should be covered to provide protection against rain, frost and snow.

Unless the work is protected there is always the risk that water in the

mortar and masonry will freeze. If there is any danger of this, then

consider using an insulating layer like hessian or quilting, which should be

kept dry by covering with waterproof sheeting. Position the protective

covers away from facework to avoid sweating and consequent staining.

Secure the covers to prevent them from being dislodged by wind and

allow the masonry to dry out before removing.

Readymade mortar is manufactured from computerised weighing systems,

under carefully monitored conditions to ensure optimum quality. Both

the finished product and all component materials comply with relevant

British Standards.

Durability

The controlled production of Readymade results in an extremely

durable product. The range also demonstrated superior resistance to

penetration by rain water, which can greatly prolong the life of your masonry

construction.
