Application Advice

Preparation of substrates

Brush the petrous/ceramic elements with a wire brush, to get a good adhesion surface, eliminating the disaggregate materials or that may damage the adhesion of the new mortar.

Wash the elements with pressurized water jet, while trying to minimize the action on masonry joints, avoiding removing the mortar.

Preparation of mortar

REABILITA RJ 35 should be mixed using continuous mixing equipment. In equipment without automatic water dosing, mix REABILITA RJ 35 in the proportion of 5.5 to 6.0 liters of water for each bag of 30 kg.

In equipment with automatic water dosing, adjust to the minimum water flow to get a good workability.

Application

After mixing, REABILITA RJ 35 should be applied manually, using appropriate equipment, to fill correctly the gaps in the joints between the masonry elements to treat.

If necessary, make an initial filling of cavities in the masonry with small pieces of ceramic mixed with the mortar. In this case, the work should be done in two steps so that the first layer of the mortar applied hardens with enough consistency for the effect.

Restrictions

REABILITA RJ 35 should not be applied in room and substrate temperature below 5ºC and above 30ºC. It has a curing time of 28 days.

In hot and/or dry weather, or in case of substrates exposed to the direct action of solar rays, previously wet the substrate beginning the application when it looks dry. In these conditions, proceed with daily watering of the executed surfaces, for one week, to keep the renders permanently moistened.

In the presence of strong wind, the application may cause cracking in the render. In this case, protect the walls to minimize the effects of the wind.
