Installation Tip: Smart Brush Selection To Reduce Solvent Evaporation

Solving the problem of Solvent evaporation

What is solvent evaporation 

Solvent cement and primers that experience prolonged exposure to air are prone to dry out/evaporate quicker than sealed units; reducing reusability & Increasing installation costs. 

What can we do about it 

 

Smart brush selection and corrected can opening/resealing can go along way to preserving your cans opened shelf life. lets discuss in more detail both oprtions

1. Smart Brush Selection

Select a brush to seals the tin

During the cementing process, sealing the solvent tin between each joint reduces air exposure and evaporation of the solvent.

The simplest method of achieving this;  insert your swab or dauber back into the tin during the curing process. The IPS daubers and swab are designed to fit the tins forming an airtight seal, whereas a flat brush will not offer this functionality ( shown in the image below). 

Swab vs brush

Select the correct size applicator for your pipework

It is also important to select the correct IPS dauber or bush for your application as most joint failures are caused by the insufficient application of cement. 

The correct size will allow you to apply the solvent or primer in the most efficient method, not only reducing the exposure time of the solvent tin but allowing you to complete t the cement joint before the solvent begins to cure. remember the hotter the temperature the less time you have to complete the joint. this may be of critical importance on a hot day with 4″ and 6″ pipe where you may only have 30 seconds to complete the application.

That said, sometimes brush selection just comes down to personal preference, meaning flat and round brushes are acceptable – just remember to seal the tin when you are finished.

2. Correct Opening & resealing of solvent cans

Solvent tins that are opened and resealed correctly can have a potential usage time of up to 6 months. Conversely, deforming the lid with pliers will prevent you from resealing correctly; leading to dry out.  

Avoid this by using the Easy Twist Can Opener
