Mapei Primer 3296

Available as 5kg or 10kg tubs

WHERE TO USE

Primer 3296 is used to consolidate and improve the surface characteristics of weak, crumbling and dusty substrates. Also suitable for external use to consolidate the surface of cementitious sublayers, render, masonry built from solid bricks, sandstone, tuff and limestone and cement/lime building mortar. Some application examples

▪ Surface consolidator for cementitious render, tuff and sandstone.

▪ Impregnator to eliminate dust from old masonry, vaulted ceilings, etc. and exposed brick masonry.

▪ Primer for skimming cementitious-based and lime-based skimming and smoothing compound.

▪ Dust-repellent consolidator for cementitious surfaces.

▪ Surface consolidator for dusty screeds before installing wood flooring with vinyl adhesive.

▪ Surface consolidator for substrates before carrying out strengthening work and applying waterproofing products to improve their adhesion.

▪ For internal use as an impregnator for cementitious grout lines with dusty surfaces to reduce their porosity and absorption.

TECHNICAL CHARACTERISTICS

Primer 3296 is an acrylic polymer-based water-dispersion micronized primer, which gives it its high penetration characteristics, even on surfaces with low porosity. Primer 3296 consolidates surfaces and eliminates dust and powder on substrates, giving them good mechanical strength. If it is used as a primer for self-levelling smoothing products, it reduces the formation of pinholes, prevents the product from drying too quickly, helps it to level off and improves its bonding properties to the substrate. Primer 3296 is an odourless, non-irritating product in water dispersion, suitable for application in areas where there are people present. Substrates consolidated with Primer 3296 are not damaged by climatic attack (rain, humidity, sunlight etc.), and the consolidation effect makes them even more long-lasting.

RECOMMENDATIONS

▪ Do not use Primer 3296 on surfaces which are not absorbent.

▪ Do not use Primer 3296 on damp surfaces or on surfaces subject to rising damp. PRIMER 3296 Dust-repellent acrylic primer, consolidator and adhesion promoter in water dispersion for masonry, render and screeds and when carrying out strengthening and waterproofing work.

▪ Do not use Primer 3296 in such an excessive quantity that it is not absorbed by the substrate, in order to avoid the formation of a surface film.

▪ If wooden flooring is being laid after treatment with Primer 3296, use only vinyl adhesives (such as Adesilex LC/R). This product is not compatible with two components adhesive and one component polyurethane adhesives.

▪ If Primer 3296 is applied in excessive quantities, check the moisture content of the substrate with a carbide hygrometer before proceeding with subsequent bonding and/or smoothing.

▪ Do not apply Primer 3296 on anhydrite-based substrate.
