The city said its test patches of methyl methacrylate, or MMA, for street lines are holding up well.

The city used the material, which is more weather resistant, along a section of Pembina Highway by Bishop Grandin about two years ago.

It said the lines are still firmly adhered to the surface.

City official Wes Delaney said the only problem the city is having with the material is that dirt becomes embedded and dulls the brightness.

But he said that once the MMA is cleaned, it returns to its bright, white colour.

Delaney said that the cost difference between the oil-based paint typically used and the MMA material is significant.

He said oil-based paint costs about 10 cents per metre, while MMA material is around $6 per metre.

He said the material would be good for certain areas of the city where high traffic volumes cause significant fading of paint.

But Delaney said it wouldn't be necessary for all city street lines.

On Tuesday, the city applied another test patch of the material along Pembina.

Promark Line Painting laid down green stripes to mark the bike lane.

Delaney said the bright green colour will be noticeable for cyclists and drivers.
