Installation - Best Practice Procedures

Whether you are installing a decorative corner bracket, external handrail panels or right through to a complete verandah, there are guidelines to carefully consider which will determine the life span of the project.

In my 20 years + associated with the Building Industry l have had the opportunity to see first hand projects that have stood the test of time and those that have failed within the first 2 years of installation. The end result is simple – the amount of care and knowledge associated with procedures undertaken in the preparation prior to installation is very important and could save you $000’s in the long run. With so many alternative products available on the market today you must take the time to educate yourself before rushing into it. Knowledge is a wonderful thing and 9 times out of 10 it’s free.

All products have key features and benefits; it is simply knowing which product is best suited for a particular job to give you the best end result. One example of such a product is sealants; with so many types of sealants available at our disposal they all have different application purposes. By simply reading the label carefully information such as recommended use and key features and benefits should be clearly labelled on each product. If still unsure of which product best suits your requirements seek professional help by asking one of the sales staff for advice.

For external application, one product that we have used with successful results for gapping has been H.B.Fuller Caulk in Colours ™ Acrylic Sealant. Some benefits are as follows:

  1. Mould and mildew resistant.
  2. Flexible; +/- 20% joint movement capability.
  3. Won’t crack, peel or split over time.
  4. Dries ‘true’ to wet colour.

Caulk in Colours ™ sealant is a flexible, water based acrylic joint sealant for use in sealing expansion and other joints in residential construction work and tiling.

There are other quality brands on the market with similar principles; you just need to do your homework before proceeding. A simple inexpensive product such as this could be all the difference that is required to prevent the process of wood rot occurring.

It is CRITICAL that all exposed end grain timber that has been docked as well as any type of rebates used be LOSP treated using Protim XJ, Quantum AQUATEC or DIMENSION 4.

Pre prime using only quality assured oil based primers before installation.
It is also highly recommended that you liberally apply a quality grade Acrylic sealant such as Fuller Caulk in Colours around the edge of the join before installation. The correct result should be one that the sealant should work its way out around the join. Simply apply a damp cloth and wipe clean any excess sealant for a clean finish.
Use only H3 class screws and nails for all external applications to prevent corrosion.

Avoid all types of rebates on all external timber projects. They are more harmful than good. Rebates only provide catchment areas for water and dust. A lethal combination, over time will ultimately lead to the process of rot.

Verandah Posts:

  1. Cut Post to desired length.
  2. Check out top square section to allow for fascia beam.
  3. LOSP treat both exposed ends including check out section for fascia with a pre treatment.
  4. Use only quality assured oil based primers and liberally coat post all over before installation.
  5. Apply Gripset 51 (Waterproof bitumen rubber membrane) to the underside of your post before you attach to post stirrup.
  6. Liberally apply a quality assured acrylic sealant along the inside edge of the checked out section on the post. Approximately 5mm right around all top and bottom edges. When the fascia beam is attached make sure that all gaps are completely sealed. Wipe clean with a damp cloth and prime the join when the sealant has set. Finish with 2x top coats of a quality assured premium grade acrylic paint.

Gable Finials:

  1. Mark and check out the back of the gable finial which will sit recessed into the gable barge board approximately a third of the way in.
  2. Liberally LOSP treat this recessed section on the back of the finial with a quality assured pre treatment.
  3. Use only quality assured oil based primers and liberally coat gable finial all over before installation.
  4. Liberally apply a quality assured acrylic sealant along the inside edge of the checked out section on the gable finial. Approximately 5mm right around all top, side and bottom edges. When the gable finial is attached make sure that all gaps are completely sealed. Wipe clean with a damp cloth and prime the join when the sealant has set. Finish with 2x top coats of a quality assured premium grade acrylic paint.

Arches, Fretwork and Handrailing:

  1. Sit the panel between the desired openings. Mark all 4 corners for plum fit and dock ends accordingly.
  2. Liberally LOSP treat all 4 exposed end grains with a quality assured pre treatment.
  3. Use only quality assured oil based primers and liberally coat all 4 ends before installation.
  4. Liberally apply a quality assured acrylic sealant along the inside edges of all 4 ends of the panel. Approximately 5mm in from the edge right around. When the panel is attached make sure that all gaps are completely sealed. Wipe clean with a damp cloth and prime all 4 joins when the sealant has set. Finish with 2x top coats of a quality assured premium grade acrylic paint.

Window Canopies:

  1. Mark and check out the cross rails to the required length of the window canopy.
  2. Liberally LOSP treat all exposed check outs on the cross rails with a quality assured pre treatment.
  3. Use only quality assured oil based primers and liberally coat window canopies, cross rails and fascia completely before installation.
  4. Attach your window canopy end panels to the house wall by preferred method ie. Dyno bolts if the canopy is being attached to a brick wall.
  5.  Liberally apply a quality assured acrylic sealant along all inside edges of the checked out cross rails and on the join where the fascia rail is to be attached approximately 5mm in from the edge right around. When the cross rails and fascia are attached make sure that all gaps are completely sealed. Wipe clean with a damp cloth and prime all joins when the sealant has set. Finish with 2x top coats of a quality assured premium grade acrylic paint. 

Important Notes:

Always make sure when you are attaching a fascia beam to a verandah post that both surfaces making contact are pre primed before joining them together. In fact this principal applies to all external timber projects. Failure in doing this is ultimately asking for problems sooner or later.

If water is exposed to any unprimed natural end grain timber that is low enough to the ground, water is absorbed into the timber.  This is very common on verandah posts. If left unattended over time the process of rot will occur and you will only notice it when it is too late. The process of rot works from the centre of the post outwards. You will notice the surface paint on the post bubbling which ultimately results in the replacement of the post.
It is very important when installing verandah posts that you have good clearance off the ground. Wind flow is very important after a heavy rain which will dry the timber eventually. The worst possible scenario is to have a post directly on the ground or very low to the ground and sitting in a puddle of water.

Regular maintenance checks should be carried out at least quarterly keeping a close eye on any movement especially in the sealed joins between two timbers. If you notice the sealant has opened up and created a gap simply reapply the sealant immediately and re paint. By carrying out inspections on a regular basis not only do you avoid the possibility of an expensive repair job or replacement part of but the time taken to fix the problem is simple yet quick. The worst thing anyone can do would be to delay any repair work and forgetting about it.

Another important note to remember is that all paints are bio degradable. Although some paints have a guaranteed life span under perfect conditions unfortunately Mother Nature is not so forgiving.
A simple method to check how your paint is holding up is to run your finger along the surface. If you notice a chalky substance on your finger this is a good indication that a re paint is near approaching. This chalky film is what we call oxidation. This is usually the first sign indicating that the paint’s chemical structure is starting to break down. Another sign to look out for is if fine hair line cracks are starting to appear on the surface of the paint. A simple light sand wiping off any dust with a damp cloth and re applying another premium acrylic top coat or two is all that is required.
