I need to re tape and glue my Marauder. I have nowhere warm to do the work. Does this mean it is now too cold to do it this year?

Ideally for standard marine resins you need to be at about 15°C or above. Below this the reaction really will proceed painfully slowly. It's not even a case of it needing to be above 15 just for the start- for thin applications like this the resin won't self heat, so needs kept warm all the way through its cure. ------------- -_ Al |

| Polythene sheeting tents and fan heaters... You do need to be indoors though or the wind will blow the warmth out. |

Inspection lamps of the type with a lamp in a cage can be quite good for this. ------------- If it doesn't break it's too heavy; if it does it wasn't built right |

Do you have patio doors? And an understanding other half? You can see where I'm going with this... ------------- RS600 1001 |

hire some heat lamps from a rental tool shop, works a treat, a few hours with a couple of them doing their stuff will sort it out! ------------- |

Believe me, this option crosses my mind very often, but my life would be forfeit...  ------------- the same, but different... |

you can get epoxy resins that set at lower temperatures from SP or gurit or whatever they call themselves these days i always use a shoe box with the ends knocked out to funnel hot air from a fan heater |

What are these resins? Last last time I spoke to Gurits technical department they would not recomend any resin properties following a cure below 15deg C. Resins generaly provide very poor properties following low temp cures, they can appear to be 'hard' but will still not have the expected mechanical and chemical properties. OP if you want to produce a good quality job wait utill the tempriture rises other wise you may a well use a polyester and save your self money. Mark ------------- Lark 2170 |
