Hi Tim,

I’ve just noticed on my first worktop mitre joint, the colour fill has come out in two places. I’m not sure how to fix this – more permanently.

Please advise.

Sorry Avart but you’ll have to elaborate on the problem.

Personally I don’t use colorfill preferring instead silicone but I am aware that any joint has to have consistency in applying sealant to be effective.

Hi Tim,

OK, I did use silicon sealant inside the mitre join area and then joined the two worktop pieces together (biscuit joint).

Now obviously, when the worktop bolts were tightened the joint gap between the two worktop pieces became zero gap, but on the top laminate surface there was still a 1mm gap. This had

to be filled with something and i chose Colorfill to match my worktop colour. The deepness of the gap is very shallow as you can imagine so the Colorfill appears to have little

ability to hold on to the surface, hence the Colorfill has come out twice after wiping the worktop after food preparation etc.
(I hope this is making sense, but if not, i’m happy to have another go)

Please advise what i can do to keep the Colorfill in or or solution from here.

Thanks.

Avtar,

To make certain that the laminate forms a tight joint you must ensure that the tops are sitting level on the units. Sometimes laminate tops have a tendency to sit unevenly and again

this happens with certain makes yet not with the more reputable names. A worktop will belly if not stored correctly prior to fitting and again this will culminate in the scenario you

have experienced.

Too late now, I know, but to overcome this you should have bevelled the joints slightly prior to applying silicone and tightening to ensure the laminate forms a tight joint.

It seems that the problem you are now encountering is that colourfill will not adhere to silicone which effectively, you are expecting it to do.
You must either discover a way of removing some of the silicone in order for the colourfill to adhere to the chipboard, fill the gap with a similar coloured silicone or remake the

joint. Not impossible if you can fit a sharp blade into it to cut the silicone but not the option I guess you wished for.

I understand what you are saying, but i cannot see any slightest hint of bellying, they do appear to be quite flat/level at

the join.

However, i think the silicon you describe may be the problem – that it is too close to the top surface of the join and thus not allowing anywhere for the Colorfil to grip on to.

I will have a closer look at this and will report back when i find a result that works.

Thanks Tim for your help.
