We all started down stairs in the classroom today.We have started our next assessment which is sealants,These are;Sillicone,Glues,Paint.Sillicone can be used on

-Metal Roofing.
-Flashings and downpipes.
-Lap joins in zincalunme,colourboard and other bhp decorative sheet metal.
-Skylights and extraction units.
-Air conditioning.
-Sheet metal.
-Aluminium,Brick,steel and Concrete.

Paints stop timber and sheet metal from rusting or rotting in weathered condtions over time.If timber is cut and the insides are exposed then paint,(primer) is then used to seal the timber to prevent moisture and rott from weaking the structural intergrity of the materials used on the job.

Sillicone basically fills gaps where water can have access to on the outside of the house.For roofing,under ridge caps and flashings for fireplace flues.This stops the capillary action,keeping the inside of the house safe from water.

After the classroom session we continued on with the build.I got stuck into the weather boards on 2 sides of the house,Cut lengths at 1955mm for one width of the house.Primed up the ends then put the boards up to the line on the building paper.Grabbed a level and sat that on top of the board then moved the other end to the correct height and nailed them off with the finishing air compressed gun,We nail the boards to each 600mm center stud.One half of the class went ahead and got into the scaffolding exercise that is required for an assessment.I will be doing that later on in the week.Mostly all the boards are up around the house now,We are ready to install flashings to the tops of the windows.One side of the house has been put on hold as the meter box needs to be put up on the house,once that has been sorted we should have it all done and ready to move on to roof iron.
