Hi friends, I am making a scratch build boat useing foam board.
But there is a two problem ,,...
1) how to join am board ?
2) how to give a  finishing touch? Useing putty or any other material

first of all if u want to join it use fevicol.and to give finishing touch use sand paper

Cyano is  good for foamboard...
otherwise araldite klear

hie......though im nt...a pro.....i wuld recommend u araldite or fevitite from a hardware store.......and other option is fevicol marine.......but u have to be a bit patient as it takes sometime to dry.. .....btw..happy builduing and oll d best

regards,
sahil

one more thing about finishing sniore......i use...a three level......finishing 1st i use a 90 grit sandpaper for rough shape and then.....i use 220 grit fr smoothering and 320 at last for final touch...also......keep in mind...the place which are to be sanded acc to the plan....keep some more margins....as improper sanding...may result in....unbalanced sides as wel as affects the looks....hope i helped uh

Hi,
Thank you friends for your suggestion .
But araldite  will eat foam  or not ...
And yeah it take soo much of time to dry  
Any other  option for joining.. fast and quick..

araldite klear takes 5 minutes to dry...no it does'nt eat foam...
it has a slightly fishy smell when drying...

feviquick or cyano does eat some foam but if its foam board ( paper backed foam) then its ok

broo....itold bout fevitite.....its similar to araldite

try flex kwik, cheaper then fevi quick, and safe for foamboard, I use the same

This will eat foam.. how did you use this in foam?

Post a pic of foam you are using

Yes arun bhaiya is right it flex kwik does eat up foam.

Though i found that it becomes like medium CA  after expiry date and can be used
on depron for joints which dont require high strength.

It doesnt react as fast after expiry date but hardens and gives same clear hard residue. So can be used for general purpose use on depron. But only after expiry date when it has turned into Medium CA consistency.


Instead of araldite klear i suggest bondtite same thing minus the smell but gives a bond of same strength if not greater.

Still I never try flex kwik on foam board.. I always use hot glue and fevicol marine..

Atlas Van Lines???
Good choice...

Yup... Topalle...
Thank you..
