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.
