Red Seal Carpenter Practice Exam

Before installing resilient flooring, it is important to make sure the sub-floor is completely smooth with no bumps, grit, or debris that could show through the finished flooring. Option B is incorrect because particle board is not a suitable sub-floor material for resilient flooring. Option C is incorrect because it suggests using plywood that is not the correct thickness. Option D is incorrect because it mentions using nail/staple, which are not recommended for installing resilient flooring. Overall, Option A is the correct answer because it specifically addresses the need for a smooth sub-floor before installation.
