Treating a heavy tarred chimney

T P Chimney Sweeps have been treating a chimney with a level 3 tar buildup using cre-away tar remove.

Creosote comes in 3 stages:

Stage 1: Black dust or fine black powder

Stage 2: A harder rock-like substance

Stage 3: Tar Tar is viscous and sticky before finally hardening with a glaze like appearance, it is a highly concentrated fuel which can easily catch fire resulting in a potentially devastating chimney fire.

So what are the reasons for creosote forming in the flue? - Burning of unseasoned wood. Your wood should have less than a 20% moisture content before it is burnt.

- Incomplete combustion (slumbering/cutting off air supply).

- Inadequate air supply for the fire.

- Cold or uninsulated chimney.

Stage 3 creosote build up can only be effectively removed by chemically treating the problem.

We use a a treatment called Cre-Away, the powder has four components that safely modifies glazed tar.

It reacts with the tar and chemically modify it changing into a substance that can be more easily removed by our rotary power sweeping.

So, how does this work? - A reactive agent neutralises the acidic creosote making it less flammable in your chimney and less corrosive to metal components. - A dehydrator adsorbs the moisture and oils contained in the different forms of creosote. A combustion inhibitor helps reduce the chance of chimney fire. - A magnesium catalyst helps break down stage 3 creosote Tar when the flue is heated.

The photos shows the Creaway product having absorbed into the tar and then easily removed by our power sweeping equipment.
