MasterSeal P688 RC

Rapid-curing polyurea concrete primer for internal and external use A waterproofing membrane applied to concrete without first using a suitable primer will not achieve a sufficiently strong bond, leaving it liable to delaminate in the future. MasterSeal P688 RC is a rapid-curing, solvent-free, low-viscosity polyurea resin-based primer that readies concrete to receive a waterproofing membrane in the least possible amount of time. Where to use MasterSeal P688 RC? MasterSeal P688 RC is a two-part primer formulated for mineral substrates such as concrete and cementitious screeds before applying MasterSeal waterproofing membranes, MasterTop flooring systems and MasterEmaco repair mortars. It can be used inside or outside. A functioning, proven damp proof membrane must be installed under on-grade concrete. What makes MasterSeal P688 RC different? This rapid-curing primer is suitable for internal and external applications and can be overcoated after just 30 minutes. Its low viscosity makes it easy to apply by roller or squeegee. MasterSeal P688 RC has excellent penetration properties, sealing pores, capillaries and cracks. It provides an excellent bond to the concrete substrate and can be used as a scratch coat.

MasterSeal P 385

A three component epoxy-cement primer for the application of MasterSeal epoxy, polyurethane and polyurea membranes on humid mineral absorbent and non absorbent substrates What is MasterSeal P 385 and where is it used? Masterseal P 385 is a primer to be applied on humid concrete substrates prior to the application of resin based MasterSeal coatings and membranes. Masterseal P 385 is mainly used as adhesion promoter for membranes and coatings. MasterSeal P 385 is also used as leveling coat for rough substrates. MasterSeal P 385 in combination with MasterSeal membranes is used in waterproofing and protection of water retaining structures like reservoirs and tanks in waste water treatment plants, in industrial installations like secondary containment, pipelines and process areas, etc MasterSeal P 385 is a special primer for use on damp substrates. MasterSeal P 385 shows excellent adhesion on absorbent and non absorbent substrates. MasterSeal P 385 is applied easily using a brush, or a trowel. MasterSeal P 385 has high permeability to water vapor and once hardened withstands high hydrostatic pressures. Which are the benefits of MasterSeal P 385 for you? Humid concrete substrates can be treated with MasterSeal P 385 without the need of drying. Fully bonded MasterSeal membrane systems prevent the water circulation between the layers even if there is a leakage, helping its detection, localization and repair. MasterSeal P 385 ensures the adhesion of the waterproofing membranes on concrete and other mineral substrates even non absorbent. MasterSeal P 385 prevents blistering and pinholes in hardened membranes. MasterSeal P 385 homogenizes substrate absorption, and levels the substrate roughness, reducing membrane consumption. Fully certified product according EN 1504 part 2 that ensures consistency in performance.

MasterSeal P 681

A special primer for the application of MasterSeal waterproofing membranes on steel (not stainless) substrates What is MasterSeal P 681 and where is it used? MasterSeal P 681 is a special primer for use on steel (not stainless) prior to the application of MasterSeal polyurea, polyurethane or epoxy membranes in waterproofing systems for roofing or parking decks. MasterSeal P 681 is a pigmented, solvent free, two component epoxy resin based primer, with corrosion protection properties MasterSeal P 681 is an essential part of the waterproofing toolbox system for roofs and for parking decks MasterSeal P 681 shows excellent adhesion on steel substrates, and can be applied both on horizontal and vertical substrates MasterSeal P 681 conforms to the EU directive 2004/42/EG (Deco-Paint directive) and contains less than the maximum limit of allowable Volatile Organic Content (VOC). Which are the benefits of MasterSeal P 681 for you? As part of the toolkit primers for the MasterSeal waterproofing systems for roofs and parking decks, MasterSeal P 681 complements the other MasterSeal P primers to ensure the adhesion of the waterproofing system to all substrates. Fully bonded membrane systems prevent the water circulation between the layers even if there is a leakage, helping its detection, localization and repair. MasterSeal P 681 ensures the adhesion of the waterproofing membranes on steel (not stainless) substrates. MasterSeal P 681 solves the adhesion problem that normal primers experience with the low porosity and roughness of steel surfaces.
