Description

A dry levelling and porous based render based on hydraulic trass lime powder, frost resistant sand and additives. Porosan Compensating Render is used as a base render for renovation of interior and exterior salt-damaged rendered surfaces as part of the Porosan restoration render system.

Keim Porosan Equalising Render (also known as Ausgleichsputz) is WTA-certified, mineral base render with high salt retention capacity and has automatic air entrapment properties ensure high porosity resulting in high diffusion rate and good drying capacity.

Preparation & Application


Substrate Preparation
Existing salt laden render should be removed to a height of approximately 800mm (very important) above the visible damage until the load bearing masonry is reached. Rubble containing salt should be removed immediately.

Remove brittle joint mortar to a depth of at least 20mm, worn out stones should be replaced. Masonry should be thoroughly cleaned without water (e.g. with wire brush), afterwards the dust should be removed (with compressed air, etc.)

A roughcast key coat of KEIM Porosan Trass Cement Render should be applied in the form of a grid in order to establish a good bond between non-absorbent masonry and the KEIM Porosan Trass Restoration Render/Compensating Render. The masonry should still be clearly visible after the roughcast coat has been applied. A setting time of 1-2 days should be observed.

Application
A 35kg sack of KEIM Porosan Compensating Render requires approximately 6-6.5 litres of water and yields 30 litres of wet mortar.

KEIM Porosan Compensating Render should be mixed with clean water until it has a thick, stable consistency. Small quantities can be mixed with a motorised mixer. For larger quantities mixing pumps may be used. Free fall mixers are unsuitable. Avoid very long mixing periods.

Irregular masonry should be prepared with one layer of evenly applied KEIM Porosan Compensating Render, the Compensating Render should have a minimum thickness of 10mm at the weakest point. Deep holes should be sealed with KEIM Porosan Compensating Render prior to treatment.

The surface should be scraped off and roughened while hardening.

Setting Time
KEIM Porosan Compensating Render should be allowed to set before KEIM Porosan Trass Restoration Render is applied, for 1 day per mm thickness.

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
1 bag (35kg) = approximately 30 litres of wet mortar, yields 1.3m² of render surface with a thickness of 20mm, equivalent to approximately 27kg/m² of dry mortar.

The stated consumption values are for guidance and depend on the nature of the substrate and the application method. Exact consumption values can only be determined by trials on the substrate.

Cleaning of Tools
Clean tools with water immediately after use.
