Pre-selected area 1 under shade where Mold & Mildew are most likely to grow.

High human traffic area is where dirt and grime are trapped within the wood

panel crack lines. This photo clearly reveals a mixture of both dirt and

mold/mildew accumulating onto surface resulting in darkening aging look. Pre-

water test shows water absorption into wood surface and spreading out in less

than 5 mins.

Day 1 – 25/02/14 Sanding of surface spreading 7 panels to remove top surface

dirt/grime and mold/mildew of which reveal the hidden wood color from within.

The area within the 2 white tape is to be cleaned with oxidizing agent only and no

pre-sanding to contrast further on 2 method statement before Seal Once

application.

After sanding and brushing away the wood dust, the inner brown wood color

came out.

NB: The 8th panel is untreated of any kind to create a differentiating line from all 7

panels and the “2 panels”.

Day 1 – 25/02/14 Light cleaning the panels surface by brushing method and

ensuring the surface is wet thoroughly for oxidizing agent to breakdown any

balance efflorescence.

Day 1 - Special Cleaning on particular spot without sanding test.

Day 1 - 15 mins of oxidizing reaction to remove aged dirt from within.

Day 1 - 15 mins of chemical reaction to remove aged dirt from within by applying

Concrete Masonry Cleaner

Day 1 - Cleaning by rinsing water till no soapy texture on all wood panels.

Day 1 - Allowing the cleaned panel to dry partially within 1 hour before Seal Once

application.

Day 1 - Seal Once 1st Coat at 1030hrs

Day 1 - Seal Once 2nd Coat at 1045hrs. Thereafter allow up to 24 hours of curing

time before water beard test.

Day 2 – 26/02/14 After Cleaning and Seal Once effect on wood panels. Spraying of

mist over treated surface for pre-test at around 10am before noon actual test.

NB: Circle area are the 2 panels without sanding but using only oxidizing agent for

cleaning before applying Seal Once 2 coat.

Water bead test at 12noon and results are satisfactory. More uniform rich wood

color is achieved from this experiment.

Pre-selected area for treatment by consultant

Day 1 – 26/02/14 Cleaning of 12 panels using Concrete Masonry Cleaner and

rinsing after 15mins of oxidizing reaction to remove dirt/grime/mold/mildew.

Day 1 – 26/02/14 Seal Once 1st Coat at noon time

Day 1 - Seal Once 2nd Coat at noon time

Day 1 - Seal Once 3rd Coat at noon time after panel shows high absorption rate.

Allow up to 24 hours curing time before water bead test next day

Day 2 - 27/02/14- 1200hr noon first round water bead test. Cleaned panels reveal

natural brown color restored versus extreme right new installed dark brown panel

of lesser wood grains and crack lines.

Day 2 - 27/02/14- 1210hrs noon second round water bead test result at random

drops.

Extreme left panel is untreated surface but cleaned with Seal Once Concrete

Masonry Cleaner and no sanding but brushing to remove dirt/grime/mildew.

Day 2 - 27/02/14- 1230hr noon result shows water beads still remain on treated

surface except a few weak points showing deep cracks on affected wood panel

surface.

Solution: Apply onto weak points if necessary to further strengthen the panels.

Untreated surface revealed high absorption rate after just 20mins. (Circle)
