Frequently Asked Question's

Q.       Why use PTT trims or angles on corners when rendering?
A.       The PTT Trims help to form the corner and keep it straight and protects the edge from damage.

Q.       Doesn’t it take longer to render a house when you have to put the trims on?
A.         No once the trims are in place you can get a perfectly straight edge to finish too using  the correct amount of render.

Q.       Why use PVC Trims or angles on corners when rendering?

A.        Because PTT PVC Trims are impact resistant they will protect corners from being chipped when hoses etc. get pulled around corners.

Q.       What about rust on the Trims?

A.        Because PTT Trims are made from PVC they don’t rust.

Q.       Won’t the trims breakdown in the sun?
A.        No because PTT Trims are UV stabilized and are made using a special PVC formulation.

Q.       Why do the PTT trims have an anchor cap edge?

A.        The anchor cap helps to lock the render and trim together.

Q.       Why do the PTT trims have triangular cut outs?
A.        The triangular holes allow for greater compound / cement adhesion between the substrate the trim and the render.

Q.        Why do you have a tearaway strip on the L-Bead?
A.         The tearaway strip helps protect the substrate it is adjoining.

Q.         What is a starter trim used for?

A.      They are used as a base for polystyrene & Hebel type sheeting  products and you can fix them to a wall and place the sheeting inside making it easier to get a neat finished edge as well as protecting the sheeting and managing water penetration

Q.      Doe’s PTT have a trim I could use for curved walls?
A.         Yes the code is 42-REA90-2.5 – the render archway trim is suitable for all arches, curves and can bend to form a circle.

Q.      Can you get custom made lengths?
A.         Yes PTT can make to order any length – the only limitations would be the size of the carton, and timing (if we can work it in with a production run).

Q.        Is there a trim to finish against a different substrate e.g. fibre cement against brickwork?
A.         Yes the code is 42-RTLB-2.5 – The render tearaway L-Bead / stop bead is perfect where there are 2 different substrates and the tearaway strip protects the foreign substrate until the render has been applied and can be removed when finished.

Q.        Is there a trim with a longer leg?
A.         Yes the code is 42-RE-01 – The large anchor cap render external trim has a 52mm leg and is great if you have rough edges to cover or require a thicker build of render. It will take 4mm-12mm of render and is suitable for the traditional sand & cement render.

Q.        Do you have an expansion joint?
A.         Yes we have designed a unique expansion joint trim that has a 2.5 & 3.5mm build on 1 side and 6mmm on the other side. It has a fully UV stabilized PVC centre with the characteristics of rubber which allows for both expansion & contraction and there is no need to fill in the gap with anything,

Q.         How can I finish around windows & sliding glass doors when I am using polystyrene sheeting?
A.      There are 2 products 1. Render Reveal Trims for the sides of the windows and Render Sill Trims for the sill(this has an industry standard 15°) both are made to suit 3.5mm & 6mm render builds and when installed correctly form a perfect surface to finish with a render texture paint.

Q.        Do you have pre meshed trims?
A.         Yes the codes are 42-RMESH for a 2.5mm build (usually used on fibre cement) and 42-RMESH-3.5 for a 3.5mm build (usually used on polystyrene).

Q.        Is there a trim that will take a bit more render than the 3.5mm but not as thick as the 6mm?

A.         Yes the code is 42-RE-4.5 – the 4.5mm anchor cap render external trim is a new addition to our range that will suit your needs.
