Hello, hope you have had a good Christmas. Last year I had about 70sqm of invictus herringbone lvt laid in my kitchen/dining area. The flooring was glued using F Ball Styccobond f48+ high temp adhesive. There are a couple of areas where some small gaps have appeared between some of the planks. These are very small gaps (less than 1mm) but now I've noticed them i can't ignore them. They are not easily visible when looking across the floor and you generally have to be looking for them. I assume this is just seasonal expansion and contraction. The gloor does have ufh and the flow temp does not go above the 27 deg limit. What would be the best product to fill these little gaps? I have come across either the xtrafloor joint sealant or a soudal acrylic sealant. Is there any recommendation as to the best product? Ideally looking for something with a bit of flex to take up seasonal changes. Also, should any product such as this be used when the floor is at its coolest (i.e. ufh off) and thus contracted most? Thanks
