Frequently asked questions

If you have any questions not answered below then please do not hesitate to contact us.

Q What is the best temperature to use the kits at ? 

The  optimum operating  temp is 24°c

Q Does the substrate temperature make any difference ?  

Ideal substrate temp would be 25°c

Q What is the lowest temperature the substrates can be ?

We recommend around  10°c this will ensure a bond but above freezing will be ok if tanks are pre conditioned to 24°c.

Q Can the application area be damp or wet? 

No the substrate needs to be dry and free from moisture.

Q Is the froth pak the same as can foam i can buy from DIY stores, if not what is the difference ?  

 Single component foam are mainly open cell foam,  most are not not water resistant and offers poor insulation properties compared to two component systems. One component foams  are also moisture curing and can take anything from 20 minutes to 2hrs to cure dependant on moisture in the atmosphere. Froth Pak  is 97% closed cell foam that uses a mix of two components to cause a exothermic reaction this in turn means foam cures fast at around 40-60 seconds so is suitable for spray applications ect. See Froth Pak operating instructions

Q How long do the guns and nozzles last? 

Nozzles  only last 45-55 seconds once the trigger is de activated if the trigger is activated again within this period you have another 45-55 seconds this is due to the foam curing in the helix of the nozzle , gun and hose sets can last up to 5 tank set changes as long as user instructions are followed and connectors and fitting are cleaned between changes using a suitable cleaning agent/spray. However the gun is a disposable item made from plastic so will wear, even the  most careful user will have to replace the gun at some point. Always keep a check on foam consistency, if this suffers it usually means the gun is wearing or failing.

Q My foam is crunchy in consistency and yellowish why ?  

You have an uneven mix in the product , this quality of foam is running A rich (red)  you are getting a ISO rich mixture. Remove nozzle ,purge the lines ,check streams are even, normally changing the nozzles will solve it , if this persists check temperature of cans ensure valves are open fully. Check condition of gun for damage.

Q My foam is fluffy soft and very White why?  

As answered above you have a uneven mix of foam running B Poly high, replace nozzle, check flow from gun with nozzles removed ensure they are even. This however is more likely if cans are cold especially in winter months. The A side is a heavier thicker material compared to the B. Warm cans to 24° celcius this should solve uneven flow rates.

Q My foam has risen well put then collapsed and turned back to liquid why ?

Your chemical is a either cold or substrate is too cold or you have a blockage on either the A or B component resulting in a one sided mix of chemical.

Q I did not get quoted sq Mtrs from my kit why ?

Yields are manufacturers measurements in optimum conditions customers will not be in optimum conditions . This is why we give a realistic yield of around 10% less than manufacturers estimates. However correct set up is key to ensuring a good yield of foam ,ensure tank sets and substrate are of an even temperature around 25° c, a difference in temperature of either tanks or substrate can give a lower yield  and also a uniform spray is needed  when spraying to result in an even spread of chemical an uneven spread of chemical again will result in a poor yield of foam.

Q I have used my kit but still have material left in the red drum but blue one is empty why?  

This can result  for 2 reasons, firstly tank may not be at correct temperature (cold)  prior to application or secondly you have a slight blockage in the (A) side of gun causing  in a uneven mix of the foam resulting in chemical being left in the red drum.

Q Same as above but I have blue left and no red why?   

as above but blockage will be on the B side.

Q What is the highest temperature the foam will with stand?  

Maximum temperature foam will stand is approximately 114° c 240° f

Q Is the foam fire proof ?

Yes the foam has a B2 fire rating meaning foam resists ignition and has a low surface spread of flame  , the foam would generally smoulder under a flame and self extinguish once flame is removed.

Q Can I inject the foam ?

A depending on where you want to inject the foam it can be done but not without risk to your cavity wall or ceiling if overfilled, we advise calling us first .

Q I have a cpds machine but the flow is very uneven what should I do ? 

Firstly are the tanks up to correct operating temperature (24°c) secondly  do you have a blockage on the gun/hose set ,try removing the gun and purging the lines clean the gun re attach and try flow again, check you have not tilted the machine back with top valves left open resulting in a blockage  of air feed pipes causing low pressure in the tank sets themselves, if this is the case the one way valves and lines will need replacing prior to starting machine again.

Q My cpds machine will not turn on but I do have power going to the machine what should I do? 

check power at fuse box/plug  is transformer a minimum of 3KVA 110v to allow correct operation of the machine, check trip switch on compressor ( refer to users manual) for trouble shooting advise.

Q What is the longest hose I should fit to my cpds ?  

You can fit upto 150ft of hose onto CPDS machine but do not spray above 60 ft high as this could result in a drop in pressure.

Q I am testing the gun with the nozzle off and I am only getting one stream why ? 

You have a blockage in the side with no chemical flow, remove gun/hose set purge the lines and fit a new gun/hose set.

Q I have connected the cpds machine to the 110 transformer but the compressor struggles why ? 

Your transformer is not able to feed both the heater and compressor you need a transformer with a minimum of 3KVA to run machine correctly.
