MonoSeal Liquid Waterproofing by Prokol

MonoSeal is a cold applied, pure polymer liquid waterproof coating for roofs, floors, or stairs developed by the Prokol Coating Group in the Netherlands. This hydrophobic solution has been in the industry for over 35 years and developed for long-term, zero maintenance waterproofing applications. MonoSeal has been specially engineered to allow a varied application arena, from repairing in line pipework, roofing, tanking, joint filling, and so on.

The applications are endless. MonoSeal is now available to the open market place and has fast become the number one choice by contractors, building owners, property maintenance businesses, and end-users for all their waterproofing applications, roofing, tanking & structural protection.

The Dutch have lived below the water table for decades and have become experts at managing changing water levels. There are no short-term fixes in this area for the Dutch, so products that are fit for purpose without maintenance are paramount. A common belief there is, “why repair a failing product with the same product?” This leads to a higher cost repeat maintenance situation. Prokol believes in low or zero maintenance solutions, so they engineer their products to outlive the life of the product or substrate it’s applied to.

The Application of Monoseal

MonoSeal is just one part of our full waterproofing range, substrates should be prepared with our fast cure primer, MonoSeal Primer-RW (1 hour cure) – contact us for more information.

To use MonoSeal simply mix part A with part B using a static mixing paddle and stir thoroughly for three minutes until it becomes a homogenous mass. Then pour onto the substrate, using a roller or rubber squeegee, cover the area that requires waterproofing until a minimum of 2 mm membrane has been achieved. Please also note that after 48 hours the chemical window to reapply a second layer of MonoSeal will be closed, so MonoSeal Primer will need to be applied to the existing MonoSeal application to re-open the chemical bond for competent adhesion between the two layers.

You must ensure that any joints and overlaps receive a minimum of a 2mm application for movement. The pot life of MonoSeal is twenty minutes and once mixed in the tin it will go through its cure process. When using MonoSeal on vertical applications or details allow the mixed product to activate for 10 minutes in the tin or simply use our MonoSeal Vertical Detail (Contact us for more information)

The product will become thicker and therefore give a drip-free application. Alternatively, for speed apply the mixed product in two separate thin layer applications, always allow for the upstand applications to continue onto the deck level (whether this is a roof, floor, or stairs) substrate a minimum of 100 mm, this will allow for larger volume tins to be mixed and poured onto the deck and rolled or squeegeed into place giving good even coverage.
