Travis Hansen, 4Evergreen Fabricators in Washington, contacted us with some information about a discovery he made while fabricating Trinity recently.  Their shop uses a CNC during fabrication which relies on vacuum suction cups to hold the slabs in place in during cutting. The vacuum pulls extensive amounts of moisture from the slab where the cups are in contact with the slabs while the rest of the slab is immersed in water.  After the slabs are fabricated and wiped down, the difference in moisture may not be that obvious. The danger then is that when the slabs are sealed, if the moisture has not balanced out, the drier areas soak up more sealer making those spots darker than the remainder of the slab and accentuating the moisture difference. And once its sealed, unlike pure water on an un-sealed slab, the moisture difference does not lighten or evaporate.

Travis found that saturating the slab with water – in his case, lying the slab down flat on a saw table or deck and puddling clean water on to the face of the slab until the entire slab was of the same uniform saturation and then letting it dry out completely eliminated the potential for moisture shadows.

How can you tell if the slab is “evenly saturated”? The drier areas will soak in the water faster than the other spots on the slab so keep applying water until the water is puddled evenly on the face or appears to be soaking in at the same rate everywhere.

This technique will also help if there is an “opposite” condition where a slab has absorbed moisture from a wet object (like laying a slab on top of another slab during drying) and has some shadowing or discoloration.

It is important that if a Fabricator notices any uneven absorption of water on the stone after Fabrication and that it matches equipment or template placements that they do NOT seal the slabs as this will likely enhance those shadows. They should soak the slabs first to balance the moisture and then let them dry before applying the sealer.

**PLEASE NOTE**  Due to the similarities between Trinity and Squak Mountain Stone, please follow the same saturation steps for Squak to prevent shadowing during fabrication.

Houseboat keeps a piece of Seattle history

A returnee to Seattle finds a dilapidated houseboat to love and revive. The remodeled home keeps peace with the city’s waterfront history by using part of the original float in the bathroom and by creating a window in the floor so all can see one of the old float’s logs. A wall of windows keeps light coming in, red cabinets warm up the main living space and remilled fir from the old houseboat’s substructure lines walls. Above it all on the roof, a new deck is just the right space for taking in the marine view.

The slate gray of the Marmoleum floor (in “Lava”) and the Squak Mountain Stone Counters (in “Thunder”) are reflected in the cladding on the ceiling — fir reused from the substructure of the old houseboat, wiped with a bluish oil-based paint to tone down its naturally orange color. The built-in cabinets are by Baywood Cabinets, in “Amber” Plyboo vertical grain bamboo
