Help with a Krick Paula IV How to glue Hull to Deck ABS
« on: February 25, 2024, 04:52:24 pm »

I need Help with a Krick "Paula IV". On how to glue the Hull to the Deck ABS. I've seen people suggest MEK And Plastruct Bondene (for styrene to Styrene and ABS to ABS) What's the working time for MEK? How do I get it in between the 2 surfaces which are about 1 1/2" in height. Same question with using Plastruct Bondene. Working time is seconds. I understand epoxies won't hold over long periods of time???  Epoxies have a longer working time that I can apply 1st to both surfaces then I can join the deck to the hull with clamps. Once I get deck and hull joined it will be very difficult getting into hull area. Thank you.

Hold on a second.
MEK got a mention in this thread as a volatile solvent which can be thickened to make pvc & abs welding glue.
The jobs in that thread required a runny solvent or solvent evaporating glue.  If MEK is not in a binder it needs a needle applicator, used from the fridge and treated with due care.

MEK is found in the two pvc/abs pipe cements in the photo. The volatility allows the cement to dry in seconds and the pipes used almost straight away.

I typed it into word and copied it to here and i get this showing up. I don't know what is happening? also it will not let me attach a photo? What is best way of joining the deck to the hull? how do I insure the plastrtut for ABS to ABS gets inbetween both joints that is about 1 1/2" high and around the whole hull. will be hard to get into the joint from inside, I have clamps about every 1 inch holding it in place. Lets see if this works this time

The liquid glues you mention will wick in to the joint through capillary action, that is, once the two surfaces are clamped together, the glue can be applied along the top edge and will run in. However, this will not provide a 100% bond across the entire faces of the parts. Back in the day of HFM kits, the manufacturer would recommend plastic kit tube cement which could be applied to one surface, then the joints brought together and clamped. The slower drying time of this type of adhesive would prevent the glue joints drying out too quickly, and allowing better penetration of the joint.


As mentioned above, plumbers pipe joining adhesive should do this, as will UHU Plast or a similar tube rather than liquid adhesive.


I would use a combination of both, thicker tube glue for the majority of the joint, and the liquid glue to penetrate the top join line and weld it.

Robbe Pull a II & III I do believe is vac formed from ABS, so the adhesive of choice is always, Stabilit Express
.... expensive but always works.

Having mucked about with quite a bit of glue recently:

https://youtu.be/XKck8lIeBLM?si=lCWQwQjmF_CEd4lK

a. I Strongly recommend testing glues out thoroughly before committing to the actual joint!
b. Not all glues are anything like what they say they are,
c. there are TWO types of plumber pipe solvent - one for ABS, one for PVC!
d. I found the Wickes PVC pipe solvent doest work on ABS
e. glues can age and lose their strength,
f. plastics used in the kits aren't always the same from kit to kit! ( but not Robbe )

MEK can be thickened to create a thicker glue, gap filling
- Add sanded / shredded / tiny off cuts of the hull into a glass bottle, add MEK & and wait for it to dissolve.

Thank you all. I ended up using Plastruct Bondene for ABS and Styrene with a syring and thin capilary tube . seemed to work any ways.

Stabilit is basically Balsa Cement. Just goes to show the search facility is under used. Nearlly sure there is a Plastic to Plastic adhesive chart on T'internet?

I wouldn't consider Stabilit Express to be mere 'balsa cement'. I have used it in the past, it is a very strong two part adhesive but not an epoxy. it consists of a viscous liquid and a powder, which are mixed together before use. It is particularly useful for bonding to polyester based glass fibre, as epoxy does not adhere well to that type of glass fibre.


I haven't see it on sale for quite a few years, but there is a similar product available from de-luxe materials that smells the same and does the same job. [size=78%]https://deluxematerials.co.uk/collections/all-products/products/fusion[/size]

Stabilit Express is nothing like balsa cement. It is a two part Acrylic adhesive. The DeLuxe Materials version is Fusion

Balsa cement is a one part cellulose based adhesive.

Profuse Agopolies, an age confusion, UHU Hart recommended for Gropener ABS kits is Balsa Cement. Search comment still good though.

Yes, this is a thing, strange as it seems. But UHU Hart is indeed good on ABS construction. As a side note I also found that the old Robbe kits that used plura plastic in their builds responded very well to cyano adhesives that did seem to etch in to the plura (Robbe three point hydroplane builder, then crasher speaking from experience.. the glue joints held even if the hull didn't!).

Can anyone define:  "Plura plastic" ?

Here's an adhesive that seems to work well on most hard plastics, including ABS.  Price is a bit better, too. https://www.ebay.co.uk/itm/164763714599
