Floors & skirtings

Clear technical answers — no filler, no invented claims.

• 

  Floors and skirtings: acrylic on top, not underneath

  Under the skirting there is mop water, movement and, on PVC, plasticisers; on top there is paint. That is two different cartridges.

• 

  Movement joints: when silicone instead of grout

  Corners, material changes, large fields and underfloor heating. Cement grout will not give.

• 

  Paint cracking on the skirting: the acrylic underneath is still working

  Craquelure along the joint is usually late shrink or acrylic that cannot take movement, not “bad paint”.

• 

  Underfloor heating: switch it off before you seal

  If you seal an expanded slab, it pulls the joint as it cools; heat also skins the bead too soon.
