Self levelling mortar

Hydraulic mortar defined by resistance or dosage. Capable of flowing and covering any part or corner of the surface to be levelled, solely as a result of its weight, without causing any segregation. It is manufactured using cements, siliceous or calcareous sands focused on a specific use, water, fibres and specific additives.

The material is transported to the site in a concrete mixer truck and laid by means of a pumping system by specialised Molins staff.

Field of application

The main applications of this mortar include regulating bases and screeds and the levelling of surfaces.
Compatible with thermal and acoustic insulation.
Suitable to restore old or poorly maintained paving.

We have more specific formulations of self-levelling mortars, depending on their use:

- C12: regulation bases for floorings made of floating parquet, wood, ceramic products and stone.
- C20: glue-down parquet flooring, underfloor heating, carpets, vinyl flooring, micro-cements and glue-downs that require greater resistance. Post-application surface treatment is recommended.
- C25: compression layers during the recovery of slabs. Each case will be studied to adapt the product to the project’s characteristics and the customer’s needs.

Benefits

Easy to application.
Daily performance: 400 m2.
Curing time: 48 hours.
No on-site stocks of cement and sand bags.
No need for cranes or forklifts.
Controlled dosage.
Optimal planimetry of the paving.
Full use of the material.
As it is pumped, no on-site waste (pallets, plastics, etc.) is generated.

Application system

Cleaning of the support before the mortar is laid: remove curing products, release agents, dust, paints, oils, etc.
Laying of the level reference points using laser technology.
Placement of a perimeter decoupling device.
Pumping and spreading of the mortar.
Compaction and deaeration of the paving.
Removal of the surface film and dust by mechanical means.
The drying time depends on the dampness of the base and the environmental conditions, which are determined by the nature of the material to be applied and the thickness of the application.
If adhesives or glues are used, the mortar surface must be brushed by machine or with a spiked steel brush when laying the final coating. At the contractor’s prior request.
The paving should not be overloaded in the early stages.
Please contact our sales manager for the planimetry requirements.
