## Description

Liquid Rubber Foundation Sealant is a coating that is easily brushed on and cures into a waterproof membrane. It can be used in many applications where you need to create a watertight seal. Foundations, ICF's, Basements, Shower Liners, Deck and Fence Posts, Planter Boxes, Metal, Wood, Concrete and more. Use Liquid Rubber Seam Tape or Liquid Rubber Geo-Textile to bridge seams, joints, vents, protrusions to create a long lasting repair or rejuvenation. Apply when the temperature is above 10C/50F including overnight temperatures. Apply to a clean, dry surface free of anything that would hinder adhesion. Typically cures within 24-48 hrs. Do not freeze. Store in a warm area. Do not apply in wet conditions or if rain is forecasted within 24 hrs. Not meant as a constant walking surface or for long term exposure to UV. Coverage - Flat/Ponding Surface - 15 sq ft/G per coat. Apply 4-5 heavy coats to achieve a 60-80 mil. (1.5-2.0mm) membrane. Vertical Surfaces: Exterior - 20 sq ft/G per coat. Apply 3-4 heavy coats to achieve a 40-60 mil. (1.0-1.5mm) membrane. Interior - 50 sq ft/G per coat. Apply 2-3 heavy coats to achieve a 20-30 mil. (0.5-0.76mm) membrane. Apply next coat when dry to touch and nothing is wet underneath; tacky is okay. Generally 4-6 hrs between heavy coats. Amounts vary depending on surface roughness. Use all material up to achieve a long lasting membrane. Avoid hot, direct, intense sunlight during application. Remove Painters Tape while still wet. Clean Up - Use soap and water or mineral oil to clean skin.

## Questions & Answers

**Q: will this work on a pond?**
A: Yes, as a matter of fact I just redid my riverbed and the pond with concrete and then applied a couple of good coats of the liquid rubber using the last coat to adhere the rocks and it is beautiful and is holding the water perfectly'

**Q: What's the lowest temperature to apply this product ?**
A: I don't think the temp affects the function of this product as it does not have a " Do not allow to freeze " requirement. It doesn't really dry as it remains pliable like rubber. I would however heed the suppliers advice and try not to apply it below 5c/40f if possible.

**Q: Approximately how many square feet will one 5 gallon bucket cover?**
A: 100-125sq ft at a 60mil thickness. 
 Bought 5, 5gal buckets to do 580sq ft of foundation and had about 1/2 gallon left over at an average of 60mil thickness.

**Q: can i use in wood? i want to do wooden pots**
A: Yes, you can use the Liquid Rubber Foundation Sealant in wooden pots or planters.  Please see the Liquid Rubber USA site for more specific application info.
