Termination to adjacent flat roof detail As with all details, make sure the area is clean and free of loose debris. A minimum 50mm overlap onto the adjacent waterproofing material is required. Apply Bonding Adhesive to the back of the membrane and also the deck… Note: Bonding Adhesive is now dark green in colour. Mate the membrane to the deck once the adhesive has become tacky. Then create a straight edge on the membrane using a crayon and cut away any excess material along the line. Apply a bead of Water Block sealant underneath the edge of the membrane. Secure the termination bar to the deck with All-Purpose fasteners. The Water Block sealant will squeeze out from the termination during

External corner detail using SA flashing The external corner is a common detail and is dealt with as follows:   Offer the membrane up to the base of the upstand and fold back enough material to get the 4” roller in to apply the contact adhesive onto the deck, the upstand, and also on the back of the membrane. Note: Bonding Adhesive (contact adhesive) is now dark green in colour.   Once the contact adhesive becomes tacky, roll the membrane towards the base of the upstand, pushing right into the angle change to eliminate any tenting. Mark a line with the crayon, at 45º from the corner. This will create the resulting V-shape on the upstand. Cut down the marked line

Fit an External Corner Using Quickseam Formflash In this installation guide, we will demonstrate how to handle an EPDM external corner detail using Quickseam Formflash. Step 1: Offer the membrane up to the base of the upstand and fold back enough material to get the 4” roller in and apply the contact adhesive onto the deck, the upstand, and also on the back of the membrane. Note: Bonding Adhesive (contact adhesive) is now dark green in colour. Step 2: Once the contact adhesive becomes tacky, roll the membrane towards the base of the upstand, pushing right into the angle change to eliminate any tenting. Step 3: Mark a line with the crayon, at 45º from the corner. This will create

Installing EPDM on Perimeter Walls and Internal Corners Once the main field sheet is adhered, the perimeter walls can be dealt with. In this step-by-step guide, we will demonstrate how to install EPDM membrane to the perimeter walls and internal corners of your flat roof project. These are potentially vulnerable areas of the roofing and are where water is most likely to cause damage if the installation is not fully watertight. Creating a perfect seal will give you the best chance of successfully realising the full potential and longevity of EPDM roofing. With the membrane 150mm away from the perimeter wall, apply the bonding adhesive to both the back of the membrane and to the area it is

How to Fit EPDM 6” Cover Strip Join In this installation guide, we will demonstrate how to install an EPDM 6” Batten Cover Strip Join. Step 1: Make sure that the contact adhesive is used on both the back of the membrane and deck surface to secure the edges. Note: The Bonding Adhesive (contact adhesive) is now dark green in colour. Step 2: With the membrane now adhered to the deck, lay the tape in situ evenly across the join Step 3: Outline with a crayon where the edges of the tape lie. This gives a guideline for you to apply Quickprime Plus. Make sure that the crayon marks extend beyond the edge of the tape around 20mm each side.

How to Make an EPDM Join with 3” Seam Tape In this installation guide, we will demonstrate how to handle a join using the 3-inch seam tape. Step 1: Ensure the leading edge overlaps the lower sheet by at least 100mm, and has a straight edge along the entire length of the seam. Step 2: Position and mark the sheet with a white crayon. The line should 18mm from the leading edge of the overlap, all the way down the seam. An 18mm timber batten is a useful tool for this. Step 3: Flap the leading edge away from the line. It may be necessary to keep it secured with various items so it will not flap back onto

EPDM Shed Roof Kit Installation Guide How to Fit an EPDM Shed Roof Kit In this guide, we will demonstrate the application process for fitting your PermaRoof EPDM shed roof kit. Our shed roof kits include everything you need to replace the covering on timber shed roofing. Fast and easy to apply, ideal for DIY. Your EPDM kit should be applied to a clean, dry and dust-free surface for the best results. Carefully prepare your shed roof by fully removing the old covering and any oil or grease spots. NB Timber shed battens are not included as a part of the EPDM roofing kit. You may choose to purchase new battens or conserve the old ones (if they are

Mechanically fixed application It is always preferable to remove the existing waterproofing from the main part of the roof, but if you are satisfied the roof deck is in a sound structural condition, only the perimeter edge waterproofing, upstands and loose materials, e.g, felt chippings, have to be removed. Once the remaining surface has been properly swept, the geotextile undercushion can be laid onto the roof surface. This protects the membrane from the potentially rough substrate.   At all perimeter edges and upstands, the RUSS (Reinforced Universal Securing Strip) needs to be mechanically attached to the substrate for the membrane to adhere to. The geotextile undercushion must be secured underneath these strips using V-plates and All-purpose fasteners. It is important

Fully Adhered EPDM Application Once the substrate in properly prepared, the EPDM membrane can be laid out onto the roof and positioned. Make sure enough membrane overhangs the roof perimeters and upstands, allowing to be trimmed later. When EPDM membrane is laid in-situ, it can take around 30 minutes to relax. In cold weather conditions, this waiting time will be extended and any folds that are sometimes present in the membrane can take longer to dissipate. The membrane is applied from the centre of the roof out towards the perimeter edges. At these edges and upstands, fold excess membrane back onto the roof. This ensures any wrinkles are removed, making the membrane easier to apply. Then fold the sheet
