I need to repair some water damaged areas due to poor flashing. To bond new OSB to the EPS foam, what construction glues can I use? In my area I have acess to Liquid Nails ( LN-950 , LN-903, PL 300 Foam Board ). It is my understanding that a Non Solvent glue should be used. In a call to R-Control, PL Premium was recommended, although both of these are not recommended for Polystyrene. I hope someone can give some good advise on this subject. THANKS.... |

You have it right. Use a poly-urethane glue and make sure the glue doesn't have a solvent in it. |

You have it right. Use a poly-urethane glue and make sure it says solvent free.
Panel manufacturers use moisture curing/air curing poly-urethane adhesives to bond the skins (metal or wood) of their panels to their foam cores (PU or EPS). The glue is viscus, translucent-brown and looks like maple syrup. It has hardly any odor to it because it has no solvent in it to off gas and is basically liquid plastic. It is unbelievable sticky stuff will bond just about anything to anything and cures very quickly.
'Gorilla Glue' brand will work, but a no name cheaper brand with the above characteristics will work too. |

You know, I've never used PL Premium in that application before, so I don't know. But I read the product literature and it states not to use it on polystyrene, which indicates to me that it must have a substance in it that is a solvent or acts like a solvent. I read further and found it did have a petroleum distillate in it. You see, even a small amount of solvent because it is trapped in a confined space, not open on the surface and therefore concentrated will offgas and melt the foam. I would pick a product that says solvent free to be sure. Gorilla glue qualifies, but pick any poly-urethane glue that says solvent free or doesn't list any petroleum based substances in it. |

If you need to adhere a skin to EPS, then I would say not. From the Loctite product page:
http://www.loctiteproducts.com/p/pl_ca_prem_adv/overview/Loctite-PL-Premium-ADVANCED-Polyurethane-Construction-Adhesive.htm
Not Recommended For
* Polystyrene Tub Surrounds
* Polystyrene, polyethylene or polypropylene

I never gave Gorilla Glue a thought, since most of my experience was with gunnable type construction glues in a tube. But in thinking about it, I believe better coverage would be achieved by using Gorilla Glue and spreading it across the entire area. Any additional comments or tips on this subject would be appreciated. |

The glue cures in the presence of moisture. So, if you apply it on a day when the air is very dry, it may not cure properly. Read the instructions for the glue, but lightly misting the glue with a spray bottle could improve and speed up the curing time. Once you spray it or if it's a humid day, you have to move quickly.
Yes, a liquid glue that you pour on like syrup might be more useful to you than a stiffer glue that is designed to hold a bead in terms of coverage. |

I bought 4 inch eps factory cut to a 24 ft diameter circle. My sales person I could bond the osb to the foam with Elmers carpenter glue. She also said any water soluable glue will workI
I plan to use the 24 ft diameter ppanel as the sub floor ffor my Yurt in alaska.
Any comments on Elmers carpentry glue would be appreciated. I will vacuum bag the panels |

I will vacuum bag the panels so if your OSB gets wet or moisture it will delaminate. Water proof glue is what is needed , typicalyl polyurethane that is water activated |

Just glueing OSB to EPS foam does not make a SIP. SIP skins are bonded to foam cores 'under pressure' to create a 'stressed skin' panel, which is another name for SIPs. The stressing (bonding under pressure) maximizes the structural performance of the the materials. You need to use the glue that EPS core panel manufacturers use. EPS core panel manufacturers use moisture curing polyurethane. An off the shelf brand of this type of glue is 'Gorilla Glue'. |

Regarding this topic, I was told by a SIP installer that a glue such as PL-300 wouldn't be a structural glue for this type of repair and that we would need to use what the manufacturer uses (a $500/pail glue). Is this true that PL wouldn't work? Is there a glue you could buy at Home Depot or Menards that would work? Thanks |

Try looking into a low-expansion foam adhesive, rather than a "gunnable" type like you mentioned. One brand is Ener-Bond. Screws onto standard foam applicator gun, it is EPS-safe and can bond even wet/frozen lumber. The key to this product is to allow it to bond under pressure.
PM me if you want more info. |
