NASH TIMBERS JULY NEWSLETTER
Nash Timbers is in the process of putting together a sample board with a selection of colours to help the client. This is still in progress as we are trying to ensure that when staining timber that the correct stain and finish are used on the correct timber species. We are finding that clients are wanting a certain colour stain and finish but this is not always compatible with certain timber species. Nash Timbers will put together a guideline which outlines the compatibility of timber species, stain and finish. Certain stain and finish increase the tanin released from the timber board which will vary the colour.
NOTE OUR NEW TIMBER DROP OFF SAMPLE POLICY
If timber samples are required, Nash Timbers will drop them off on a Thursday. Please ensure that you get your request in by Tuesday, if staining required request needs to be in by Friday the week before for a Thursday drop off.

2) PROBLEMS THAT ARISE
Send your question and test our knowledge!!!!!
F.A.Q
Does ply expand and contract? YES
Ply is a manufactured timber product which means it has similar properties to timber flooring so it will expand and contract depending on it's moisture content.
OOPS!
The builder has methodically installed his floor as per Nash Timbers recommendations but within a couple of months the floor has cupped.
Why has my flooring cupped I have done everything correctly?
David asked the builder did you test the moisture content of the ply before installing the floor. Unknown to the builder the ply had become wet from a burst pipe in the slab before they commenced work on the site.
If the ply or timber joist are wet it will alter the moisture content in the floorboard which can cause the floorboard to cup.
DO YOU UNDERSTAND THE IMPORTANCE OF USING CORRECT PLY, GLUE AND NAILS?
WHEN YOU ARE GETTING A QUOTE FROM A FLOOR INSTALLER ENSURE YOU ARE GETTING WHAT YOU ARE PAYING FOR.
A CHEAPER QUOTE CAN BE GIVEN AS A CHEAPER ALTERNATIVE CAN BE USED.
WHICH WILL COMPROMISE THE QUALITY OF THE FINAL OUTCOME OF THE FLOOR?
OVER THE NEXT FEW POINTS I HOPE TO GUIDE YOU THROUGH THE MAZE OF COST CUTTINGS THAT CAN BE USED WITHOUT YOUR KNOWLEDGE.
I WANT YOU TO BECOME AN INFORMED FLOOR EXPERT.
1.A moisture barrier to be used on a ground floor substrate as it reduces moisture between ply or timber floor to decrease the expansion and contraction of these products.
If a moisture barrier is not used the cost saving is $3sqm.
2.Carrying flooring and products onto site.
Cost cutting if builder does it saving of $2 per sqm.
3.When using ply ensure that you are using a reputable Ply. a certain Chinese ply can delaminate and very toxic glues are used in the process of manufacturing the sheets.
Cost cutting if using cheaper ply a saving of $1 per sqm.
4.Ply installed by pinning is done usually downstairs, drill into concrete with six and half SDS diameter bit.install with split anchors 75mm long, hammer below surface of the ply, 22 anchors per sheet.
Cost cutting if using only 10 per sheet a saving of $10 per sqm.
5.Ply is installed in a brick pattern, flooring is laid at a ninety degree angle over the ply by using this process movement of the ply is eliminated when the moisture content changes in the floorboard and the ply..
Cost cutting not using brick pattern has a saving of $10 per sqm.
6.Stamp on ply must be visible, as this is the correct face of the ply to adhere floor too.
7.Expansion gaps of approximately from 4mm to 10mm depending on the width of the room and allow for 5mm to 10mm under skirting board. this allows for the expansion and contraction of the ply.
8.If the outside is meeting the inside as example verandah ensure that the builder has installed a damp course.
9.Ply to be flat sanded if floorboards not installed immediately onto ply.
10.When gluing ply must trowel out with 5mm trail & the whole area must be covered with glue. (Recommended glue Shelly's direct stick)
Cost cutting if using only spot gluing a saving of $10 per sqm.
11.If ply is not pinned or glued correctly, the ply will move & it will squeeze which gives a noisy floor & when sanding you get chatter marks due to movement of ply..
12.If ply gets wet due to other trades you must let the floor installer know as the ply sheet might need to be replaced as it may cause the floor to move & glue will not adhere ..
13. When gluing floorboards to joists use a sausage gun with Sika flex to allow for expansion & contraction. If you don't glue joist, when the floorboard expands the nails will move and a space is created because there is no glue and with time the top nails may need to be re punched If a cheaper glue is used with no flexibility same result occurs. Worst of all your client ends up with a squeaky floor! (Recommended glue Sika flex)
14. ND Nails galvanized recommended do not use C BRAND for installing as heads are not big enough.
15. Note the difference of prices of glues per sqm
NO GLUE $ 0.00/ SQM
CHEAP GLUE $1.00/ SQM
MAXIBOND $ 5.00/ SQM
SIKA BOND_T55J FLEX $ 8.80/ SQM
SHELLY'S DIRECT STICK $ 10.00 / SQM
16.NASH FINISHES RECOMMENDS SIKA & SHELLY'S DIRECT GLUE AS WE HAVE CONDUCTED TRIALS GLUING TIMBER TO CONCRETE & THESE PRODUCTS HAD THE BEST RESULTS.
17.Nash Timbers tips on achieving a high quality outcome for installing a floor
A Ensure that you get a break down on cost for installing a floor.
B Ensure the correct ply, glue, nails are been used and correctly.
C Ensure correct species is used with finish.
D Ensure correct width & thickness is suitable for site.
E. Ensure no moisture is present under floor.
F Ensure not to spill water on floor.
G.Better outcome if you use the same installer and floor finisher (One company).
Finally the Perfect Plywood designed for under Timber floors.
Ever heard of the saying “A chain is only as strong as its weakest link”?
This principal is no different with the Timber Floor you specify. Many Builders & Architects continue to risk laying expensive floors on cheap, inferior plywood. At a glance, ply woods may look the same but many are produced using poor manufacturing techniques and cheap glue lines. This can easily cause delamination after a year or more resulting in expensive repairs or replacement of the entire Timber floor.
For peace of mind it’s as simple as Evaply, the Plywood that comes with a
100% manufacturers warranty against Delamination.
Using an A-Bond waterproof, boil-proof glue, Evaply is the highest quality Plywood available in C/D grade 12mm, 15mm & 18mm (2400mm x1200mm).
For that extra protection Evaply also have Termite-Treated Plywood available in all 3 sizes.
At Nash Timbers we only specify Evaply for our Projects because we care that the job will last. For more information on the product please contact us.
