Make Roads and Streets
Sections marked “A” and “B” in Fig. 58 require a piece of 1/4" Foam Sheet placed
between the tracks as a level foundation for the road.
1. Notch Track-Bed 3-1/2" wide for the 1/4" Foam Sheet pieces. Follow the same
steps used for placing Hydrocal Inclines. Notches should be centered on the
road path.
2. To size the Foam to fit tightly between the two sets of track, press a piece of
Foam Sheet gently down on rails to make an impression
(Fig. 65)
.
3. Using a hobby knife, cut approximately 3/16” inside the impressions and trim
for a close fit.
4. Test fit and trim if necessary. Use Foam Tack Glue to glue in place
(Fig. 66)
.
Repeat Steps for section “B.”
5. At the low end of the Inclines, begin laying Paving Tape along outside edge of previously drawn lines to create a form
for the road when pouring Smooth-It
(Fig. 67)
.
6. Make roads a section at a time. Mix appropriate size batches of Smooth-It according to package instructions.
7. Starting at the low end of the Inclines, fill road forms with Smooth-It and use the Spreader to level evenly with top of
Paving Tape
(Fig. 68)
. Work efficiently, Smooth-It has a 15 minute working time.
8. Following the street plan
(Fig. 58)
, lay strips of Paving Tape along outside edge of lines defining streets
(Fig. 57)
. Street
edges need to line up with the roads leading into an area. Mix an appropriate size batch of Smooth-It. Pour immediately
and use the Spreader to smooth level with top of Tape.
9. Let all roads dry completely (approx. 30-40 minutes), fill any holes with Smooth-It and sand smooth with fine grade
sandpaper.
10. Remove Paving Tape.
Add Curbs, Sidewalks and Foundations
1. Place a new strip of Paving Tape on top of street edges where you want curbs, sidewalks and building foundations. Then,
place two strips of Paving Tape parallel with outside of edge of street, not wider than 4". This will elevate the area above
the street.
(Fig. 69)
2. Mix another batch of Smooth-It. Pour and use the Spreader to smooth level with top of Tape.
3. If it is necessary to make a building foundation wider, stack two strips of Paving Tape parallel with the edges. Prepare
another batch of Smooth-It and pour between existing foundation and Paving Tape. Spread smooth with the Spreader.
4. Let dry 30-40 minutes, then remove Paving Tape. When completely dry, sand smooth with fine grade sandpaper.
