DRAINING anti-damp mortar
Breathable anti-damp mortar
with salt-retention capacity: DRAINING
Breathable anti-damp mortar
Immediately after installing MURSEC ECO to treat rising damp, and without waiting for the wall to dry, the walls can be rendered with DRAINING anti-damp mortar, which significantly speeds up the drying process and prevents the effects of salt crystallisation.
1
Paint after 15 days
DRAINING mortar can be applied immediately after installing MURSEC ECO and can be painted after 15 days using breathable paints.
2
Highly breathable
The micropore network allows moisture to evaporate from the wall. We do not work by sealing or waterproofing, but through diffusion and permeability.
3
Salt-resistant
Its internal structure is designed to retain hygroscopic salts. This helps prevent flaking and efflorescence typically caused by saltpetre.
4
Cost-effective shipping
DRAINING POWDER is shipped in 200-gram bags. Ideal for minimising transport costs. Simply mix it with Portland cement and sand.
Our experience speaks for itself
DRAINING mortar: a complete solution
Our partners can take care of the entire drying process, providing a complete and definitive guarantee. No excuses.
Microporous DRAINING mortar replaces existing render that has already been damaged by moisture and salts, allowing moisture to escape from the wall.
DRAINING anti-damp mortar has exceptional properties and can be applied to stone, brick, concrete or any surface other than lime, plaster or cement mortar.
DRAINING mortar is available in different formats:
– DRAINAGE POWDER (200 g sachet): Ideal for minimising transport expenses and reducing costs.
– BLANC DRAINING (25 kg bag): Quick-setting, ideal for painting after 2 weeks.
– DRAINING CAL (25 kg bag): NHL 3.5 lime-based. Ideal for buildings of historical value.
– DRAINAGE EXTRAFINE (15 kg bag): extra-fine 2 mm float finish
DRAINING POWDER is the best option for most of our partners, as we can ship it easily and at a lower cost. Simply mix the 200-gram bag of DRAINING POWDER with 25 kg of sand and 6.25 kg of cement. The mix will allow you to render 1 square metre while retaining all the breathability properties of DRAINING mortar.
DRAINING mortar is the ideal complement to the MURSEC ECO system. It is recommended to replace the existing damp render with microporous DRAINING mortar from the outset. Bear in mind that once the moisture level in the wall has decreased, any damp render that has not already been replaced with DRAINING mortar will also need to be replaced. Accumulated hygroscopic salts retain moisture and can even absorb humidity from the air.
Immediately after installing MURSEC ECO, and without having to wait for the wall to dry, damp-damaged walls can be rendered with DRAINING dehumidifying mortar.
DRAINING mortar allows the wall to dry and prevents the effects of salt crystallisation. The wall can be painted after 15 days using a breathable paint.
On our video channel, you will find practical tutorials explaining how to replace the render step by step.
