On aconstruction or renovation site, thequality of thesubstrate determines the durabilityof all the finishes thatare applied to it. Paints,wall coverings, or decorativecoatings requireflat, sound, and homogeneous surfaces. It isprecisely to meet thisrequirement that Parexlanko — a brand of theSika group — has developed the 102Lankomur Ragrepar, a walllevelling compound in paste form recognized andused for over 40 years onprofessional sites.
Its formulation based on synthetic resins,mineral fillers, andadmixtures gives it a creamyand stable texture, readyto be mixed with a binder — Portlandcement or plaster — without any additionof water. Once the mixture is made, thepaste takes on the colour of the binder used,ensuring visualand mechanical homogeneity with the substrate. Its opentime when mixed with Portland cement is1 to 2 hours depending on the temperature,allowing the applicator the necessary timeto workcomfortably.
The application capacity of the 102 Lankomur Ragreparranges from 1 to 10 mm in thickness. Thiswide range makes it the ideal toolfor addressing various and sometimes pronouncedsurface defects: blisters, gravel nests fromsegregation,non-flush formwork seams, oreven irregularities in flatness oncast concrete walls andundersides of slabs. Its grain sizeof less than 0.40 mm ensures asmooth and even finish,ready to receive thefinal coating.
The application processis accessible and quick. Usinga stainless steel trowel orby mechanical spraying for large surfaces,the product is applied in twominimum passes: a firstto fill and correct thedefects, a second toperfect the finish. The time towait between the two passes is3 to 4 hours at +20 °C. Theremarkable glide quality of theproduct reduces physical effort andexecution time evenon large-scalesites.
- Adjustable thickness from 1 to 10 mmto adapt to all levels ofdefects, from simple irregularities tospot fillings of significant blisters.
- Perfectly smooth finishthanks toa grain size of less than 0.40 mmand optimal glide quality withthe stainless steel trowel or bymechanical spraying.
- High adhesion on concretegreater than 1 MPa at 28 days inPortland cement mix for areliable and durable bond on allacceptable substrates.
- Versatile for indoor/outdoor:walls, ceilings, cast concrete, prefabricatedcellular concrete panels,plaster, brick tiles — a single product for awide variety ofsubstrates.
- Ready-to-use paste without adding water,taking on the colour of the binderused after hardening forhomogeneous integrationinto the substrate.
- Professional product Parexlanko (Sika group) a must-have referencefor concrete substrate preparation forover 40 years.
