 The Liquid Cladding System

Code mark
The Liquid Cladding System is a comprehensive water entry prevention system for walls, specifically designed for all types of monolithic clad residential, industrial and commercial buildings. The System is Code Marked for a series of specific processes beginning with Moisture testing and the determination of rot or mould through to the application of membranes and the installation of Wi-Fi sensors.

The Liquid Cladding System is based on the simple premise that if the damaged areas can be identified and repaired, the integrity of the cladding is re-instated, your home is made watertight, then you no longer have a “leaky” problem.

The Liquid Cladding System is the world’s first integrated system for protecting and monitoring cladding performance against moisture ingress. Systems developed in New Zealand with the expertise of UK and USA chemists and scientists.

Finding out if your house is watertight

Not all building reports are equal
The engaging of a company to look over your building has often resulted from issues you or others have found in your building. You may be recommended to a particular company to carry out a report. Not all companies have your best interests in mind and not all reports are aimed at serving you. Often a report will create anxiety and fear. The key questions you must ask are;

  • Does the report indicate temperature and relative humidity readings at the time of the test
  • Does the report show evidence of the moisture readings?
  • Does it explain the equilibrium moisture content expected, based on the environmental readings, what should it be?
  • Is there a Baseline reading – what is the moisture content of a known dry area in a room?
  • Were non-invasive or invasive readings taken?
  • Were there thermal images to show the readings?
  • Are recommendations aimed at more reports to be done… or a course of action to repair the problems found?

At no time are generalised assumptions made, guesswork or blanket decisions reached to carry out re-cladding on a building.

Making your house watertight

It doesn’t have to be “leaky” to benefit from the System

1. Preventative

You can benefit by using the Liquid Cladding System even when you don’t have a leaky home. Prevention is always the best thing. We are now told some of the texture cladding systems were not designed to last longer than 20 years. By applying the Blue Barrier Total Building Envelope Wrap you re-instate the existing cladding’s integrity; its strength, its durability. The superior qualities of this product alone virtually creates a “new” cladding. Along with a purpose-designed Link Primer and New Zealand’s best, tested Elastomeric Coating, proprietary made for the System, the cladding effectively is new!

2. Repairing and Cladding Re-instatement;

The repairs on the exterior can be sealing around the window surrounds, panel joints, corners and cracking. It may be necessary to re-texture these repaired areas. Prior to this it may be necessary to remove areas of damaged framing. A lot of the time this can be done from the interior, but if sections of the cladding need to be removed, these can be rebuilt and the cladding re-textured. All risk areas are then gapped using the Blue Barrier Flashing sealant.

There are 2 choices at this point; the application of a full Blue Barrier Wrap prior to top-coating or if this is not required due to the existing claddings condition, then just the top-coating can be applied. Read more – (link to monolithic specialists) But it is recommended to do the full system and get the full benefit of a fully integrated and monitored system that carries the comprehensive Warranty.

3. Future-Proofing Maintenance

Seamless Coatings Ltd join with Building Science and ABEP to offer a comprehensive maintenance programme as part of the Liquid Cladding System. A requirement of the 10 year Warranty, a simple house wash is scheduled every year. It makes sense…if you wash it, the coatings will last longer. At the same time the LCS representative will inspect the cladding to see if there may be any issues.

If issues are found these can be addressed early to avoid damage occurring. If problems are found that are due to our workmanship these will be rectified at no cost.

Liquid Cladding System is the only system that provides an ongoing performance guarantee providing peace of mind to home owners at a price they can afford.

Liquid Cladding System- the products

What makes the system so good

The system employs all of the processes indicated above. The application of the Blue Barrier Wrap is one big key factor to the exterior coatings. It is a liquid membrane based on STPE technology (silyl terminated Polyether) which has been around for 25 years and mainly used in the US and Europe in the construction and residential industries.

Because of its strong bond to almost any surface, even in wet conditions, it lends itself to many applications, more commonly used as a liquid applied air and moisture barrier at the pre- cladding stage of new buildings. It is code marked for this application in NZ and being specified by Councils on projects currently.

Its uniqueness is its ability to breath. Waterproofing is generally designed not to let water in or out. If a wall coating prevents the interior to expel the normal build-up of condensation, this is what can contribute to the building structure to rot. Blue Barrier won’t let any water in but allows vapour out.

This is breathability.

This factor alone is paramount for the cladding issues of Monolithic houses, and in the past, has been problematic in most other coating systems.
The next most important attribute is flexibility. The Blue Barrier products have 300% elongation. That is like wrapping the house in a tight, flexible, rubbery skin!

With all the areas fixed, the cladding is ready for top-coating. Liquid Cladding System has developed its own Link Primers and Elastomeric top-coats that are compatible with the Blue Barrier and better than any equivalent product on the market. It makes sense that the flexibility achieved by sealing cracks and joins is continued through to the top layer. In NZ conditions, flexibility is vital.

With many of the leak problems originating from the deck areas, it is vital that these are rectified with better products. Fibre-glass mesh systems, although still an approved system, consistently fail to perform on ply substrate decks, where movement of the sheets create ripples and in time split leading to moisture ingress.

The FFR-K1 liquid membrane, also from ABEP, is designed specifically for flat areas; decks, roofs and internal gutters. The Kevlar-infused membrane adheres to almost all materials, is flexible, fully appraised and comes with a 20year global warranty.

What does the Liquid Cladding System Cost?

An approximate example comparison

Picture1

All of the homes we are asked to apply the system we come and do a full itemised quote addressing all the waterproofing areas, decks, flat roofs and of course the cladding. There may be re-texturing to do also. Scaffolding and clear wrapping may be necessary to add in. The Moisture technician addresses the testing and monitoring costs which can vary dependent on each individual projects requirements, but this is generally included. If only the moisture testing is done this and the Report is billed separately.
