Cut asfa in the easiest way...

[Crebel]

How to cut (kapa) asphalt easily and neatly?

The circular saw shreds the edges, cutting by hand is too slow. Scoring with a knife on the asphalt side and breaking works okay, but it would be a stretch to say the edges are tidy.

Does anyone have better tips?

Decent edge = fogsvans. I personally cut most of it with a knife.

I mostly used the hand circle.
Well, the edges were hardly as nice as the factory-made ones but I didn't really care, and the blade looked terrible afterward.

Nah, I don't have any better tips. :blushing:

Something like this might give nice cuts... d^_^b

As I mentioned, too lazy for a handsaw !
A jigsaw from the asfa page was what finally turned out to be good enough for me...

Hi

There are blades for Jigsaws... Might work if you don't feel like doing a few strokes with the handsaw

Best regards, Wasa

The hand circle set to the minimum cut depth and support plate works fine with it.

Hand saw set to the smallest cutting depth and the support plate works fine with that.

Should one use a blade with few, or many teeth?

For asphalt. Many.

But in my opinion, a jigsaw is easiest if you don't have access to a good table, because then, as tossegubben wrote, the circular saw is absolutely the best.

Tried different methods when we were building. The one we settled on was using the jigsaw.
Insert an old blade, take the angle grinder and grind off the teeth from the sides, so it becomes like a knife (or buy a ready-made one).
The best thing about this method is that it doesn't create dust when sawing.

If you start with taping and then saw, it frays much less. Then it's fine with the circular saw.

 

[Tossegubbe]

Haven't noticed any direct difference but sharp teeth and support are important.
That is, I take a piece of form-ply or thick masonite, fully raise the blade and attach this piece of board under the table on the circle and plunge cut through it with the smallest possible depth to get through the asfan and then screw to the depth stop.

In hindsight, I can add that a utility knife with a new blade became the favorite. Sometimes I cut from one side, turned it over and cut from the other, sometimes I just cut from one side more times. The cleanest cut, no dust, and if the asfa boards are stacked with the asfa side down so you don't score the asfa layer in the next board, you can use the stack of boards as a workbench.

to take a circular saw? well, you'll damage it very easily and a blade costs money...
the easiest in my opinion is to take the drywall knife.
as simple as that....

This is an old thread, but I wanted to thank you for the tip on using a jigsaw! The board was purchased at Byggmax, I took a regular blade and sanded off almost all the teeth. The result was very good! The cut surface is what you see. I ran it without support behind.
