Chalk building protection

This case study shows how Cook Group specified a unique paint coating to offer long term protection to a 200 year old chalk building

 Chalk Building Protection System 

The Property

The property is a detached mainly random chalk & lime mortar construction house, converted from 3 old farm worker cottages. The property is situated next to a busy A road in a very exposed position in East Yorkshire

The Problems

After a severe winter the chalk stone was deteriorating quite rapidly, the existing paint coating was failing. surface spray, road salt & other pollutants were damaging the building during wet weather also.

Our Brief

The property owners called us in after recieving poor advice from non specialist contractors (they shall remain nameless!) who could only think to cover the building in a cement render and then paint it with masonry paint! The owners wanted to preserve the building, make it look better and do it cost effectively! So our brief was simple - design a system that was better & cheaper!

Our solution

Our solution was simple, gently clean down the existing stone, carry out sympathetic stone & pointing repairs using reclaimed chalk and a lime mortar, consolidate the random stone construction where necessary using a specialist pourable grout. Then  apply a specialist coating system called the MC Betonflair system.

The MC Betonflair protection system is a water baes pure acrylate that is specifically designed for use where road salts & other pollutants can be an issue and importantly is also open water vapour diffusion, this means that whilst protecting the structure from frost, penetrating damp & road salts it also allows the walls to 'breathe'. This is extremely important for buildings built using lime mortar and particularly chalk!

Another benefit is that the Bentonflair system lasts far longer than traditional masonry paint coatings.

Saving the best till last, our system was less than a third of the price others had given for rendering the property!

Result

The result is a happy client & a protected property that won't need painting for years to come.

The MC betonflair system is one of many in our inventory to offer unique & cost effective solutions to individual building problems.

Betonflair can also be used very effectively on concrete, render & masonry structures
