View delivery optionsView product description
For bedding seams, mouldings, rails, window and door frames and many other types of covered joints in portable buildings, caravans, holiday homes,
boats, freight containers and transport vehicles.

Soudal Butyrub is a Polybutene Based Non Setting Mastic which forms an elastic tight skin that can be painted over after 24 hours.

Surface preparation: All surfaces must be clean, dry and free from frost, grease and loose materials. Apply primer if required. In situations where an
especially neat finish is required, use masking tape to cover the face edges of the joint and remove immediately once tooling has been completed
Cut the top of the screw thread off the cartridge and screw on the nozzle. Cut nozzle to correct diameter for joint size. Apply using a skeleton or powered gun
into the joint ensuring good contact with surfaces.

Application temperature range: +5ºC to +30ºC
Curing: Seamseal CV cures by evaporation of solvent. Full cure normally occurs in 2-4 days. Rate of cure will depend on thickness, ambient temperature, joint size and design. Lower temperatures and drier conditions will result in a slower rate of cure.
Priming: Primers are not normally required for good adhesion to most metals.
Shelf life: 12 months when stored in cool, dry conditions.
Skinning time: Does not skin. The surface of the sealant will appear dry to the touch after several days but will remain pliable beneath the surface.
Working time: Approximately 20 minutes.


  • High performance bedding sealant with a solvented release curing system.
  • Good adhesion to a wide variety of surfaces, especially coated metals.
  • Excellent application characteristics either with hand applied or air operated
  • Easy to tool and clean off using Hodgson’s Caravan Sealant Cleaner.
  • Does not form a skin but leaves a dry surface which remains pliable after
  • Excellent weather resistant properties.
  • Good performance in low movement joints.

Does What It Says

What is there to say about a sealant? It does what it says.


4 star review(4/5)
This Hodgson Mastic Non-Setting Caravan Sealant was easy to apply and went on where I wanted it to thanks to the nozzle - some nozzles are too big, but not this one. I was very pleased with the price and it was an excellent purchase. My only concern will be its longevity, but that is something I can only wait and see on that.

Great Sealer

worked perfectly, you do get sticky using it so lots of white spirit and gloves

Non Setting Mastic

Bought this to seal shower and sink. Expected smaller tube in 2 aspects, I misread ad' had to borrow industrial sized gun, but will come in handy again. Just the job.

Non Setting Sealant

5 star review(5/5)
Ideal product for sealing around components that penetrate the shell of the caravan. I used it on a replacement water housing and around the fridge vents. The component can be removed and repositioned. The cartridge is about 20mm longer than the standard DIY cartidge. I had to chop 20mm off the tube to be able to fit it into my DIY dispenser.

this is an excellent product and gives a very good seal on all joints bought the Carafax sealant to reseal joints on motorhome panels, and find it easy to use.


5 star review(5/5)
The carafax sealant arrived quickly and was put to good use when i fitted a new vent in my van. The sealant consistency is excellent and the screws pulled down nicely to allow the sealant to do it's job. This is incredible value sealant which made a refreshing change.

Caravan Non-drying Sealant

5 star review(5/5)
all though I have not yet used these tubes of sealer I have in the past and find them very good, one tip is to put the tube in a bowl of hot water as in cold weather there harder to squeeze in the gun.


5 star review(5/5)
It does what it says on the tube.

Caravan Mastic Sealant

5 star review(5/5)
arrived fast, found it to be horribly gooey, sticky, in fact PERFECTLY SUITED to sealing damaged panels on this old caravan ---- some left so used on open cille joints on an old Triumph Stag -- IDEAL. Now wondering wether this is ok as anti-nagging device for 'er indoors ?? maybe not, far too useful in my workshop. Forget Screwfix & B&Q, These are my prefferred suppliers in furure

3 FAQs on the Soudal Butyrub Non-Setting (Permanently Plastic) caravan sealant (White)


I have a 7 year old Dethleffs advantage motorhome with Heki 3 plus skylight which has just started leaking slightly. Having looked at your technical drawings it looks as if the only sure way to solve the problem will be to remove it completely and reseal. Am I right in this assumption and if so is this as straight forward as it would appear? I am a bit concerned that removing the old sealant may not be easy. Could you please advise: 1. what I am likely to need to remove the old sealant 2. what sealant should be used 3 there also appears to be a rubber seal beneath the other frame - will this need replacing at the same time? 4 can i get all the required parts from you? Thanks in advance for your help


This is a straightforward job providing a non setting sealant was used during manufacture. Once the fixing screws have been removed then the frame should lift away from the roof of the vehicle. The ease with which it lifts will depend upon the sealant used. We recommend using a non setting sealant when replacing such as our ref. 205932. The old sealant will need to be removed with a chisel type tool.
The rubber seal should not need replacing unless it is cracked.


I asked for advise on which sealant is recommended for Seitz S4 windows when fitting a new rubber outer frame to outer wall seal on my caravan. On 10th. August & 29th August 2013. I have not yet received the Seals ordered from yourselves. But I would appreciate an answer to my question, as I do not wish to use a wrong Sealant for this situation. Many Thanks.

We would normally use a non setting mastic such as the Carafax IDL.


Hi I have just purchased a REMIS 400 skylight from you, can I use Sikaflex 512 as a seal between the skylight and the roof
by Tony Taylor


Yes you can but it is not easy to remove should you need to change the rooflight in the future, We normally use a non setting mastic such as Carafax IDL.
