Preparation & Application

Substrate Preparation
Remove loose material and old coats mechanically or with a water pressure jet. All loose and friable material should be cut back to a sound level.

Preparation
Keim Restauro Fuge is to be mixed only with clean cold water, approximately 5lt per 30kg. For larger quantities use stirring machine or mixer. After a ripening period of 5 minutes the mortar should be of light flow properties. For moulding silicate resin moulds should be used.

Application
Press the prepared joint mortar firmly into the joint with a jointing tool. The new joint material should not be smoothed at the surface. For flush joints, Keim Restauro Fuge should be applied proud of the stone surface and any excess then removed with a palette knife during setting.

Application Conditions
Ambient and substrate temperature above 5°C and below 30°C. Do not apply in direct sunlight or onto sun-heated surfaces, nor if it is raining or if there is an immediate likelihood of rain.

Consumption
Approx. 0.2kg per linear metre for a joint depth and breadth of 1cm x 1cm. Determine actual consumption by tests on trial areas. Consumption rates are offered for guideline purposes only. Actual rates are the responsibility of the applicator. Project specifications should be referred to for specific rates.

Cleaning of Tools
Clean tools with water immediately after use.
