Weiss Cosmofen RM SP-710.110 White PVC, uPVC Window, Door, Dent or Crack, Impact Resistance Repair Mass Kit 19 Grams

Easy to use and an excellent product. Fixed my patio door perfectly. Hardens quickly and made the fix simple.

Does the job, but overpriced for the amount you get.

This product does what it says but what it doesn't tell you is that when you mix the Hardner in the small tub as per the instructions it sets solid in about 1.5 to 2 mins. The heat that's generated in the tub is remarkable. The end result was that I managed to fill 24 3mm holes in a conservatory with about 3 seconds to spare before it went solid so at least half the contents went in the bin as a lump of plastic. It does a good job of filling the holes and set very hard but at £17 total cost it's ridiculously expensive.

I needed to fill a couple of screw holes in a UPVC window frame that had become too large when the previous screws became damaged after they had loosened causing the window to jam shut. I was able to fix the holes & re-drill with the correct size screws so now the window works fine. I didn't pour all of the fluid into all of the powder as suggested in the instructions. I estimated 50% of each and was able to carry out a another small repair. Get everything ready for the job before mixing as it goes off quickly

Only problem I had was that you have to use all of it in one go. No tool for proportional mixing.

Used to repair cracks in UPVC doors.Mixes readily and easy to apply though as others have noted it does go off quick, so you can't hang about!Rubbed down with wet&dry paper on a block and it looks great,even if I say so myself. I can see the colour is slightly yellower than the white of the door but I think unless you were looking for it you wouldn't notice. Certainly less noticeable than the cracks.

Damaged my pvc window frame mixed up the product and filled the hole rubbed down finish was great well pleased

Had to repair cigarette burn in window frame,what a amazing finish.Definitly use it again.
