For pedestrian waterproofing applications, we recommend our rubber aggregate for its resilience, flexibility, lower surface deck temperature, low moisture absorption, and provides an excellent feel and wear.

For a sanded finish on pedestrian decks, we recommend #2/16 deck-coat sand. Its a fine grade which is washed and kiln dried for the best quality sanded finish decks.

For vehicular traffic areas, we recommend the coarser #2/12 deck-coat sand for enhanced wear resistance and greater slip/skid resistance.

Where substrate adhesion is questionable, primers should be used. Primer-733 is an easy to use one-component solvent based sealant primer for metal, wood and coated surfaces. A favorite of many deck waterproofing contractors is Polyprime 2180. Its a 2-part epoxy-polyamine primer. For an easy to use on-component wood and concrete primer, try Primer-722. Uni-Tile Sealer is a two-component, quick drying epoxy-polyamide penetrating primer/sealer which penetrates and seals porous surfaces to improve adhesion -- excellent on concrete and pool decks.

Read all MSDS sheets before using materials. The illustrations below are intended as a general guide and not a replacement for factory procedures. Single component systems need to be applied in warmer weather (60F+ is best). Practice your technique first.

Basic Process for Waterproofing Balconies:

We recommend the Sonoguard deck coating waterproofing system together with rubber aggregate for new applicators. It is easier, faster and less prone to problems than other systems. Rubber aggregate systems have many benefits over sand (greater elasticity of finished system, cooler decks, rubber does not sink into basecoat, topcoats last longer over rubber, ease of repair and touch-ups). On the other hand, sand decks will have a more consistent surface appearance. Troubleshooting Guide.

Concrete Balconies (old or new) (wood decks are below):

1. OLD Decks: Remove and scrape away all old loose or cracked coatings, caulking and sealants. It is especially important to remove ALL silicones or silicone residues.

2. Pressure wash concrete, using 3000 psi minimum washer. Remove all loose surface materials or old coatings and any oil based stains. Let dry 1 to 2 days.

3. Expansion Joints and Cracks: Dynamic Crack Details, , 1-2 inch Wide Expansion Joint Details.

4. Be sure final the concrete surface has some "texture". Smooth surfaces will need to be blasted to create a good bonding surface. As an alternative, you will need to use epoxy 770 primer using a 1/4 inch nap phenolic core roller. (All new concrete must be fully cured before work begins). Primers, if needed, are applied just before base coat and only need to dry tack free. Sonoguard 770 Epoxy Primer Info, 1/4 inch Nap Phenolic Core Roller Cover Info.

5. Caulk and Seal: Prime all metal surfaces using 733 primer before caulking. Use NP-1 or Novalink to fill any big holes or cracks. Let sealant cure 24-72 hours. 733 Primer Info, NP-1 Product Info.

6. If needed in cricket areas, apply 4 inch WEBSEAL at the corners, deck-to-wall interfaces and all other high stress leak-prone areas. Webseal Roller Tool Product Info.

7. Bridge all deep field cracks, joints and flashing areas by apply 4 inch white fiberglass 20 X 20 mesh tape embedded in Sonoguard basecoat or NP1 sealant. Use a 3-course process to hide seams. This is much like taping a drywall joint wherein you taper joint to adjacent surfaces. NP-1 Product Info, Fiberglass Webbing Info.

8. Let NP-1 or basecoat / taped areas cure a minimum of 24 hours.

9. Blow off surface and work area using a high power gas blower.

10. Remove and y skin and pre-mix Basecoat 5 minutes with a drill and mixer. Do not whip air into coating. Apply Sonoguard Base Coat at 2 to 2-1/2 gallons per 100 sq.ft. using a 1/4 inch notched squeegee, then back-roll to smooth out using a phenolic core (solvent proof) 1/4 inch nap roller.

Hint: First apply basecoat to all perimeter edge areas and up the edge of all flashings using a disposable brush. For highly sloped surfaces order "Flash Slope" basecoat to prevent excess running of basecoat.

11. Within about 20 minutes, while material is wet, broadcast rubber granules at rate of ~ 20 lbs per 100 sqft. (fully cover all of base coat with a full layer). Broadcast by throwing it out by hand. Rubber Granule Info. Do not roll after applying.

If Using Stand: A second basecoat must be applied after the first basecoat has cured, and the sand is broadcast into the 2nd layer. Do not put sand into the first basecoat layer. The second layer only needs to be thick enough to adhere sand (about 1 gallon per 100 sq.ft.) Do not roll after applying.

Hint: How to broadcast Rubber or Sand? Toss each handfull up in the air over the area to be covered. It should come down evenly, in the same direction, so there is no angle to to contact. Broadcast until no basecoat is visible. If sand or rubber is wet or sticky, do not apply. Do not roll after application. Let things cure overnight before brooming off excess.

12. Mark off area with Caution tape to keep off traffic during cure periods. Wait 1 to 2 days for cure, depending on heat and humidity. Base coat cure can be accelerated by misting with water. Caution Tape Product Info

13. When you are ready to begin topcoat, broom way excess rubber. Then blow off the rest using a high power gas blower.

14. Remove any skin and pre-mix Topcoat 5 minutes with a drill and mixer. Do not whip air into coating. Top Coat with Sonoguard Topcoat at 1-1/4 gallons per 100 sq.ft. using a phenolic core (solvent proof) 1/4 inch nap roller and roll out of a paint tray, being careful to get the excess of the roller before applying (do not dip in the bucket and roll on, you will apply too thick of coating). Do not apply topcoat with excessive thickness. Pooling areas and too much thickness can result in small blisters on hot days. ALL custom tinted products need TWO topcoats. Standard Sonoguard pre-tinted topcoats will benefit from a second coat. Most Polycoat System topcoats require two coats.

Hint: First apply topcoat to all perimeter edge areas and up the edge of all flashings using a disposable brush. If the top coating has globs in it which do not disappear with power mixing, then strain topcoat through painters sock into the paint tray before applying.

15. Mark off area with Caution tape to keep off traffic during cure periods. Let cure 48-96 hours before traffic (depending on temperature and humidity).

16. If a high traffic system is required, add a 2nd layer of topcoat at the rate of 1 gallon per 100 sq.ft.

Maintenance: Clean using soap, natural bristle scrub brush or street broom and water. To maintain integrity of system, recoat top layer when rubber granules begin to show (~ 5+ years). Street Broom Product Info

Helpful Notes and Hints:

• Remove any "skin" off the top of Sonoguard material before mixing or starting application. Thick skin can be cut with a razor knife and removed in one big piece.
• It is HIGHLY recommended to do a trial area first to practice your technique (an old piece of plywood sheet works good).
• When re-sealing cans, be sure and completely wipe sealing surfaces clean. Otherwise product in this area will cure and permanently glue the lid to the can.
• For both basecoat and topcoat, begin by brushing materials up wall, over Webseal and all around perimeter (do all the detail work first). Then apply material to the field.
• Use vinyl gloves. This material is hard to get off. Use WD40 to remove from your skin. Vinyl Glove Product Info
• Clean-up using Xylene, which you can buy at your paint or hardware store. Remove from your hands using WD-40. Caution: Protect your skin and eyes from xylene.
• If the basecoat has to set for some period before the final topcoat can be applied, cover the deck with 6 mil black plastic sheet. This will protect it from UV damage as well as contamination from other trades. This cost about $1.00 per 100 sq.ft. This investment is more than save in the clean-up needed prior to topcoat.

To Shorten the Deck Coating Process:

Deck coating technicians can save one day of process time by using PC50 accelerator and Polycoat 440 for seam caulking in lieu of NP1. Make a paste of these materials, about 1-2 quart at a time, and 3-course your seams with fiberglass deck webbing as in previous process. This is a process which needs to be practiced before using. Mixing ratio is about 1/2 pint of PC50 to 1 gallon of PC440, depending on cure rate desired and the days temperature. This material can also be poured into low spots to build them up. Let materials cure to tack free before applying base coat layers over the top.

Caution: This seam materials must completely cure before applying base coat over it. In cold weather, it may take a full day or more, even with the accelerant. PC-50 Product Info, PC440 Product Info

Wood Based Decks / Balconies (new balconies):

1. Deck should be constructed of exterior grade plywood, 3/4 inch minimum thickness, tongue and groove, knot free on outside face. Plywood should be screwed down using deck screws. We recommend gluing beam faces before attaching plywood (glue and screw). Deck Screw Product Info, Screwdrivers, Collated/Automatic, Electric.

2. GRIND down or rest all screw heads which are not completely set to deck level. DO NOT hammer them in. This will cause loose decks and seam failures. Also grind any high wood areas (steps) along the seams. Good preparation is the key to good decks.

3. Under all metal, use a bead of NP1 caulking sealant and use NP1 caulking on both the balcony face drip-edge metal to wall interface and deck top interface. Attach all metal flashing (generally its nailed).

Ultra-low rise drip edge is recommended at the balcony edge. High lipped edge metals will cause ponding water along the edge. Clean metal with acetone or xylene and a rag, the apply 733 primer on all metal surfaces immediately before application of NP-1 Sealant or any base coat. ALL metal must be primed. Low-Rise Deck Edge-Metal Product Info, NP-1 Product Info, 733 Primer Info.

4. At all high stress areas, including metal-to-wood interfaces and deck seams, apply 4 inch white fiberglass 20 X 20 mesh tape embedded into Sonoguard Basecoat or NP1 sealant. Do this using a 3-course process (coating, fiberglass, more coating, then feather out) to hide seams. This is much like taping a drywall joint wherein you taper joint to adjacent surfaces. Again, on all metal surfaces, apply 733 Primer before application of basecoat or NP-1. Plywood Seam Details, NP-1 Product Info, Fiberglass Webbing Product Info.

5. Let NP-1 (or basecoat) cure a minimum of 24 hours. It can take 48 to 72 hours in cold or very dry weather. Water mist will accelerate the cure.

6. Blow off surfaces and work areas using a high power gas blower, air or thoroughly broom.

7. Remove any skin (use a gloved hand if needed) and pre-mix Basecoat 5 minutes with a drill and mixer. Do not whip air into coating. Apply Sonoguard Self Leveling Base Coat at 2 to 2-1/2 gallons per 100 sqft using a 1/4 inch notched squeegee. Then back-roll to smooth out the material using a phenolic core (solvent proof) 1/4 inch nap roller. Back-rolling is important. Back-rolling brings air from the surface of the deck to the top of the basecoat so that it can escape, and evens out the thickness.

Hint: First apply the basecoat to all perimeter edge areas and up the edge of all flashings using a disposable brush. For highly sloped surfaces order Slope Grade basecoat to prevent excess running of basecoat. IN COLD WEATHER, DO NOT USE FLASH SLOPE. IT WILL BE TOO THICK (use two thinner coats of self leveling).

Sonoguard Self Leveling Base Coat Product Info, Notched Squeegee Product Info, 1/4 inch Nap Phenolic Core Roller Cover Info, Disposable Brush Info, Mixer Info.

8. Within about 20 minutes, while basecoat material is wet, broadcast Rubber granules at rate of ~ 20 lbs per 100 sq.ft. (fully cover all of base coat with a full layer). (Broadcast by throwing it out by hand). Rubber Granule Info. Do not roll after applying.

If Using Sand: A second basecoat must be applied after the first basecoat has cured, and the sand is broadcast into the 2nd layer. Do not put sand into the first basecoat layer. The second layer only needs to be thick enough to adhere sand (about 1 gallon per 100 sq.ft.) Do not roll after applying.

Hint: How to broadcast Rubber or Sand? Toss each handfull up in the air over the area to be covered. It should come down evenly, in the same direction, so there is no angle to to contact. Broadcast until no basecoat is visible. If sand or rubber is wet or sticky, do not apply. Do not roll after application. Let things cure overnight before brooming off excess.

9. Mark off area with Caution tape to keep off traffic during cure periods. Wait 1 to 3 days for cure (depending on temperature and humidity). Cure can be accelerated by misting water onto surface. Caution Tape Product Info.

10. When you are ready to begin topcoat, broom away excess or loosely attached rubber with a stiff broom. Then blow off the rest using a high-power gas blower.

11. Remove and skin and pre-mix Topcoat 5 minutes with a drill and mixer. Do not whip air into coating. Apply Sonoguard Topcoat at 1-1/4 gallons per 100 sq.ft. using a phenolic core (solvent proof) 3/8 inch nap roller out of a paint tray, being careful to get the excess of the roller before applying (do not dip in the bucket and roll on, you will apply too thick of coating). Do not apply topcoat with excessive thickness.

Caution: Too thick of material or pooling areas and can result in small surface blisters. Apply only enough material to cover the sand or rubber granules, but not to cause material to pool. ALL custom tinted products need TWO topcoats. Standard pre-tinted topcoats will benefit from a second coat. Most Polycoat Systems require TWO topcoats.

Hint: First apply topcoat to all perimeter edge areas and up the edge of all flashings using a disposable brush or mini roller. THEN apply top coating to the center areas. If the top coating has globs in it which do not disappear with power mixing, then strain topcoat through painters sock into the paint tray before applying. Sonoguard Topcoat Product Info, 1/4 inch Roller Cover Product Info, Disposable Brush Info.

12. Mark off area with Caution tape to keep off traffic during cure periods. Let cure 48-96 hours before traffic (depending on temperature and humidity).

13. For custom colors (when using tintable Topcoat with Color Packs) deck surfaces, a second layer of Topcoat is recommended to achieve good color coverage. For white or cream color decks, sometimes a 3rd coat is needed. You will need an additional 3/4 gallon per 100 sq.ft. per coat.

14. If a very high traffic system is required, add a 2nd layer of topcoat at the rate of 3/4 per 100 sq.ft.

15. If you are using TINTABLE or darker color topcoat, apply it in TWO thin coats (allowing it to cure between coats). This provides the best coloration and long term resistance to fading.

Troubleshooting:

The most common deck coating problems and causes are:

Basecoat:

• Poor curing, lumps: Failure to mix thoroughly by power mixer before application; very dry climate (moisture is needed for cure).
• Bubbles: Wet or contaminated deck; extreme hot temperature or deck surface.
• Plywood splits and splinters: Basecoat applied over particle board deck, not exterior grade plywood; plywood was rained on before base coat application.
• Splits: Wood deck nailed not screwed; screws missed joists; too few screws; poor sub-framing (add more or double the joists); plywood was rained on before basecoat application.

Topcoat:

• Lumps: Failure to remove skin before mixing; poor mixing; failure to strain before putting into roller pan.
• Poor Cure: Failure to mix thoroughly with a power mixer; failure to apply topcoat out of a roller pan; too thick of topcoat applied, wrong nap size used (use 1/4 inch nap only).
• Poor Coverage: Failure to apply 2 topcoat layers; too thin of material applied.

See Maintenance and Helpful Notes from Concrete deck above.
