Consider the weather |
The right sequence | |
| Now you have assembled all the materials, tools and equipment you need, the final consideration before beginning your roofing job is the weather. Try to ensure that the weather will be dry all day and if possible conditions warm. | It is advisable to plan the sequence of your roofing job to ensure that you have the right materials at the right time. If in doubt read these instructions through completely first noting down the sequence in which you will use these materials, | |
| Temperature awareness | Guard rail warning | |
|
The Coldseal
material is easiest to work at a temperature over 10 deg. C. If it
is difficult to achieve this temperature whilst working on the
roof, it is recommended that the material be stored in a warm
environment for 24 hours prior to use. If it is necessary to work on the roof in cold weather, then the gentle warming of the adhesive side of the felt with an electric hot air paint stripper or similar (not a naked flame) will help the adhesive properties of the material. If temperatures become extreme it is advisable to postpone the project until more favourable temperatures pertain. |
For roofs above 2 metres high it is essential that a safety guard rail be erected around the perimeter of the roof. At this height ladders should be fixed to the guard rail and secured at the foot to prevent slipping. | |

| Make good and mend. Inspect the conditions of the existing roof structure and deck prior to commencement of roofing. Make any structure repairs that are necessary and ensure that the surface area of the roof is free from obstructions, smooth, clean and dry prior to the commencement of the project. | ||

STEP 1. Preparation and Priming Page 7 of fixing manual |
||
| Quicktrim Preparations | ||
|
|
Provide a softwood timber batten
50mm x 25mm mechanically fixed to the roof perimeter. The batten
should be flush with the surface of the deck. There is no need to
install separate timber check kerbs or angle fillets. Where applicable, cut to length and fix the Drip Edge backing plate to the external face of the batten (flush with the top) with pins provided, through the pre-drilled holes as required. |

Fig. 8 Preparation & Priming |

| For simplicity, these instructions deal with flat roofs for garages and extensions. | Prime surfaces | |
|
New Roofs For new roof structures, first ensure that materials used are suitable for the purpose. Please refer to pages 4 and 5 of this guide for information about suitable materials for roof structures. Existing Roofs. For an existing roof, where the material needs replacing, strip off all old roofing felt and covering, fill knots, large holes and gaps in the timber or other material deck surface. Flatten or cut of any projections that may interrupt or interfere with the smooth line of new roofing material. |
Prime all deck surfaces to receive
the Coldseal membranes using the Coldseal SA Primer. Prime all
walls up to and including the chase following the instructions on
the Coldseal S A Primer can. NOTE: The Coldseal SA Primer is not a waterproof coating for flat roofs; it is only preparing the deck surface to receive the Coldseal Underlay. Using other primers may result in incompatibility with the Coldseal Underlay |
